#  1. Introduction.

The principal aims of the NE-CAT collaboration are the design,
construction and operation of undulator and bending magnet-based beam
lines for biological crystallographic data collection. Said beam lines
will be highly automated, possess high brilliance and narrow band pass
suitable for optimized MAD crystallographic data collection.

The resulting beam lines will be used mainly in support of NIH National
Centers for Research Resource (NCRR)-funded core scientific
collaborations. The core scientific collaborations involve a wide range
of structural interests including: biological signal transduction, DNA
transcription (initiation and regulation), cell cycle regulation, virus
structure and function, protein folding and protein synthesis (ribosome
structure). NE-CAT will also reserve a portion of operational time to
support biological crystallography by independent researchers.

The main technological challenge of the NE-CAT NCRR proposal is the use
of the tandem-offset undulator concept to increase the number of
concurrently-operating undulator beam lines at a single APS sector. Beam
line construction will be split into four phases, summarized in Table
1.1.

The following list details the overall performance goals for all 4
sector 24 beam lines:

1)  Phase I: "Pass-Through" Undulator Beam line. The first beam line
    developed (using the upstream, outboard-projecting undulator) will
    consist of a single optical train, supplying a single experimental
    end station with doubly focused monochromatic light from 5 to 25
    KeV, with a nominal band pass of order 10^-4^ (E/E).
    Monochromitization will be accomplished by a cryogenically-cooled
    double crystal Silicon Bragg monochromator. A Kirkpatrick-Baez (K-B)
    mirror pair will focus the monochromatic beam.

2)  Phase II: "Single-Crystal Side-Bounce Undulator Beam line. A single
    crystal, side-bounce cryogenically-cooled 220 silicon monochromator
    will accept the residual beam from a diamond-transmission
    monochromator using beam from the downstream, inwardly projecting
    undulator (see Phase IV, below). The side-bounce mono will deliver a
    monochromatic beam near 12.6 KeV, with a nominal take-off angle (2θ)
    of 29.54^o^ from the centerline. The 220 Si crystal will be mounted
    on a cooling stage that incorporates a vertical translation. A
    second silicon crystal (311-cut) will be mounted on this stage, with
    independent roll and pitch fine adjustments such that a second
    energy (14.78 KeV) will be selectable by a vertical translation of
    the cooling stage (following the same 29.54^o^ take off angle
    provided by the 220 crystal). This beam line will also use K-B
    focusing.

3)  Phase III: Bending Magnet Beam line. The third beam line developed
    by NE-CAT will use the bending magnet port of the assigned sector.
    The Phase III beam line will incorporate a water-cooled Si-111
    monochromator with sagittal focusing, providing a spectral range
    from 5 to 17 KeV (2 eV bandpass). Vertical focusing will be
    accomplished with a mechanically figured mirror.

4)  Phase IV: Tunable Large-Offset, Side-Bounce Undulator Beam line. A
    pair of beam lines will be sourced by the downstream,
    inboard-projecting undulator. Monochromatization and physical
    separation of the Phase I and Phase III beam lines will be
    accomplished with a large horizontal-offset (1.5m) diamond
    transmission monochromator, with a spectral range between \~8.5
    and17 KeV. The undiffracted radiation is passes on to the Phase II
    Fixed-Energy Side-Bounce monochromator. As with Phases I and II,
    Phase III will use K-B focusing.

This document presents a detailed preliminary design for Phase III
bending magnet beam line only. A separate PDR for the NECAT build phases
I and II has already been submitted for review and approval. The Phase
IV beam line will be developed during the first renewal phase of our
NCRR funding, probably starting sometime in 2007.

The NE-CAT Phase III beam line will be constructed form optical
components recycled from an existing beam line: sector 8 BM (also owned
and operated by NE-CAT). The phase III hutches will be constructed
during fiscal 2006. After commissioning of NECAT Phases I and II is
complete, we will decommission sector 8BM, transport all optical and end
station components to sector 24, and following a general refurbishment
of the motion and vacuum system, the beam line will be reconstructed at
sector 24 BM. The lineal order, distance from source of all optical
components at sector 24 will be very similar to the present 8BM
configuration. The major difference in the optical configurations of 8BM
and 24BM will be the effective demagnification of the monochromatic
beam. The 8BM beam line operates with a 1:1 demagnification ratio. The
overall layout of sector 24 will require that we operate 24BM with an
effective demagnification of 1**:**3.5 (vertical) by 1:2.6 (horizontal).

# 2. Beam line Technical Specifications.

# All four sector 24 NE-CAT beam lines are single-purpose, fixed configuration macromolecular crystallography beam lines. The following functional elements must be provided by the various beam line subsystems:

-   Shielding and safety systems must include enclosures for the optics
    and the experimental hardware and be capable of protecting personnel
    from radiation and equipment from such faults as loss of power,
    cooling fluid, etc.

-   Optics systems must be capable of delivering a focused monochromatic
    beam with long-term positional stability to a sample 40-60 meters
    from the radiation source. The required positional stability region
    (horizontal and vertical) is a square of edge length 10 microns with
    a characteristic time measured in hours.

-   Beam transport systems must convey the beam from the sector front
    end to the sample position via ultra high vacuum paths to minimize
    intensity loss (due to absorption) and scattering background.

-   Utility systems must provide conventional infrastructure such as
    plumbing of water and compressed gases; electrical power; HVAC
    capability; liquid nitrogen; and mechanical support.

-   Control systems must provide interactive (and secure) local and
    remote control of all optics, sample handling and detection
    subsystems.

-   Front ends, insertion devices and dipole magnet must provide an
    X-ray beam with an energy range of at least \~5KeV to \~30 KeV.

-   The lab and office module must provide for mechanical equipment
    setup and maintenance; wet laboratory capability for sample
    preparation; and office space for operations staff and data
    reduction. The required performance characteristics for the four

**2.2 Phase II single-crystal side-bounce beam line using the
inboard-projecting undulator**:

**3. Component Design.**

This section describes mechanical and optical components of the Phase
III sector 24 BM beam line from the front end to the experimental end
stations.. First, a comprehensive list of all optical, mechanical and
vacuum system components is presented, followed by a per item
description of principal optical components.

**3.1 Component Listings.**

Figure 3.1 consists of plan and elevation views, of the layout for the
Phase III bending magnet beam line.

Table 3.1 sequentially lists major optical or beam line components of
build phase III and calls out their displacements from the center of the
bending magnet tangent point. Column 3 of Table 3.1 calls out drawing
number and provenance for said drawing or a vendor part number. Column 4
provides a brief description of each component and indicates the source
of the design. All components indicated by an "M" designation are
modified APS standard components, with modifications imposed by NE-CAT.
Principal optical component descriptions are rendered in bold text in
column 4.

Appendix 8.1 contains detailed assembly drawings and descriptions for
all principal optical components, including masks, collimators,
monochromator, mirror systems and shutters.

**4.1.2 Ozone Mitigation.**

There are no open-air white beam paths in any NE-CAT optical plan. In
addition, all hutches have two widely-separated ventilation systems that
continuously withdraw air from the hutches (see section 8.2.5 of the
hutch specification document in Appendix 8.2).

**4.1.3 Program-Specific Hazards.**

No program-specific hazards are identified at this time.

No special operating requirements have been identified at this time.

**4.2 Equipment Protection System.**

Table 4.2.1 identifies operational criteria of those build Phase III
optical components that are routinely or possibly exposed to white-beam
radiation that must be monitored to insure safe operation of tabulated
components. All ion pumps have an associated ion gauge controller. If
the measured pressure at any ion gauge exceeds a preset threshold the
appropriate gate valve(s) will be triggered to close. This closure will
in turn trigger closure of the front end valve via EPS logic.

We will use the same general set components used at Sector 8-BM and
Sector 24-ID (DirectLogic 405 PLC modules) to construct the sector 24
Equipment Protection System (EPS). The sector 24 BM EPS will
continuously monitor these criteria and when any corresponding sensor
state falls out of band the EPS will automatically signal closure of the
BM front end shutters. Resetting of equipment conditions that elicit EPS
fault trips will be necessary before the EPS fault signal can be
cleared. Only read access to the state of the EPS will be available to
beam line control software and offsite operators.

**4.3 Personnel Safety System (PSS)**

**4.3.1 Design Scope**

The following list establishes the scope of the PSS design effort
specific to NE-CAT build phase III. No NE-CAT radiation enclosure
requires personnel access with beam enabled.

**Enclosure Enclosure Function Enclosure Type**

> 24-BM-A First Optics Enclosure White Radiation
>
> 24-BM-B (PHASE III Experimental White Radiation**\*\***
>
> End Station).
>
> **\*\*Note:** 24-BM-B will be built and commissioned to white
> radiation standards for convenience of commissioning the enclosures,
> themselves. After installation of the optical train only monochromatic
> radiation can enter 24-BM-B, due to the mask and white stop
> incorporated in the P7-20 integrated shutter situated at the
> downstream end of 24-BM-A. Only monochromatic operations will take
> place in 24-BM-B after installation of the beam line's optics.

**4.3.2 Components requiring Interlocks**

**4.3.3 Shutters**

Only the P7-20 Integrated shutter situated at the downstream end of
24-BM-A requires PSS interlocks.

**4.3.4 Doors & Search Buttons**

Figure 4.1 shows a tentative layout for the sector 24 PSS layout,
including placements of all doors, search buttons, door override
buttons, PSS panels, warning strobes, enunciators and mirrors for
viewing into obscured corners. This layout was established in
consultation with a representative of the PSS group.

**4.3.5 Components requiring administrative control**

The drawing of Appendix 8.2 shows placements for all roof and side panel
labyrinths. All labyrinths will require administrative control.

**4.3.6 Radiation Enclosure Action Logic**

Except for commissioning activities all sector 24 beam lines operate in
one mode only: monochromatic beam delivered to experimental end
stations. The following tables explicitly call out the action logic for
sector-24 enclosures.

**8.2.2.4 Collimating Mirror** (Oxford Instruments \# AMH 0400).

The white beam is collimated by a water-cooled silicon mirror with a
fixed meridional spherical surface figure, situated upstream of the
monochromator. A water-cooled copper mask is emplaced upstream of the
collimating mirror to protect the but-end of the mirror from
mis-steering. The mirror has two vertical slots milled into its working
surface (top), on both sides of the reflective strip. The slots are
filled with a liquid gallium-indium eutectic. Two water cooled copper
slats are inserted into the eutectic fluid, without contacting the sides
of the slots.

**8.2.2.6 Double Crystal Monochromator** (Oxford Instruments AHD 0220).

The monochromator (DCM) is a fixed exit, water-cooled (first crystal)
design from Oxford Instruments, and uses silicon 111 crystals. The
second crystal is a sagittally-bent uncooled design derived from an ESRF
system designed by A. Fruend. Figure 8.2.3 is an isometric projection of
the DCM crystals and mount, and Figure 8.2.4 shows various projections
of the entire DCM. Table 8.1.3 lists salient properties of the DCM,

**8.2.1. Scope.**

This document presents the requirements for the fabrication and
installation of shielded radiation enclosures for the Northeastern
Collaborative Access Team (NE-CAT) bending magnet beam line, 24-BM. A
separate, document describes installation of utility requirements (e.g.
Personnel Safety System, electricity, cooling water, compressed air,
associated support structures) for said enclosures.

Two enclosures are to be constructed of one type:

1\) 24-BM-A \"White-Beam\" enclosure (quantity 1).

2\) 24-BM-B "White-Beam" enclosure comprising Experimental Station
(quantity 1).

Both enclosures are contiguous, separated by an internal partition with
sufficient lead shielding to be considered part of a "white-beam"
enclosure. The bending magnet beam line Experimental Station Enclosure,
24-BM-B, abuts the existing First Optics Enclosure (FOE) 24-ID-A of the
Sector 24 insertion device beam lines, through its most downstream wall
as shown in Drawings 21-000009-00 and 20-000010-00. Although only
monochromatic radiation will be permitted to enter the Experimental
Station, it will be constructed to white-beam standards to simplify the
process of validating the overall structure in a timely manner.

The NE-CAT Sector 24 design is based upon the tandem-offset undulator
concept and will consist of 4 beam lines, commissioned in 4 build
phases. The bending magnet beam line comprises the third phase of
construction. Note: the nomenclature used in referencing the NE-CAT beam
lines and the order of their construction has been changed since
submission of the generating documents for the insertion device
radiation enclosures. The following table summarizes these changes:

**8.2.3. General Requirements.**

**8.2.3.1 Shielding Requirements.**

The shielding shall be designed, fabricated, and installed in accordance
with Document No. 410509-00002 "Technical Specification for APS Beam
line First Optics, White and Monochromatic Beam Experimental Enclosures
(April 13, 2004)". Table 8.2.4 summarizes required lead shielding
thickness on a per-wall, per-enclosure basis.

+-----------------+-----------+------------+-----------+--------------+

In addition to the above specified wall thicknesses, two standard lead
guillotines (0.6m wide by 1.6m) of 12.5mm thickness of lead shall be
provided, one on the downstream wall of 24-BM-A and the second on the
upstream wall of 24-BM-B (see Section 3.6). Also, a 12-inch square 25mm
thick lead beam stop shall be installed on the downstream wall of
24-BM-B.

\* The upstream wall of the existing ID-24-ID-A enclosure serves as the
downstream wall of 24-BM-B and has a lead thickness of 19mm.

**8.2.3.2 Construction.**

The 24-BM-A enclosure will be a structure fixed to, and supported by,
the floor of the experimental hall and the wall of the storage ring
tunnel. 24-BM-B will be contiguous with 24-BM-A and 24-ID-A and
supported by the floor of the experimental hall and the wall of the
storage ring tunnel. These enclosures shall be modular in construction.
Each enclosure drawing outlines the standard panel size for the
enclosure. These panels shall be manufactured as a steel-lead-steel
sandwich with a steel frame welded to the inside wall. The assembled
panels must make-up a structural system capable of supporting the
enclosure and attached equipment. The vendor shall be responsible for
the structural and radiation integrity of the enclosures and shall
attest that a certified structural engineer reviewed their design.
Design loads shall include loads that can be found during construction.
Loads mentioned below include dead (stationary) and live (moving, such
as people) loads.

The joint between the existing 24-ID-A enclosure and the new 24-BM-B
enclosure shall be made with a corner lead plate. This plate shall
overlap the ID-A upstream wall by a distance equal to or greater than 10
times the maximum expected gap between the two surfaces to be joined.
For example, APS recommends a 0.5m corner lead panel for a ½-inch
lead-lead gap..

The enclosures must be built with sufficient in-built safety factors to
withstand the load imposed by manual bridge hoist systems with a load
capacity of one ton in both of the radiation enclosures.

**8.2.3.3 Hand Rail-Utility Support Structure.**

A handrail system identical in construction to that used for the 24-ID
enclosures shall be installed along the outboard (relative to
accelerator) roof margin of 24-BM-A and 24-BM-B and attached to the
existing 24-ID-A hand rail system. A stretch of hand rail on the
upstream margin of 24-ID-A shall be removed, once the hand rail systems
for the bending magnet enclosures are installed. The hand-rail is to
meet OSHA standard 29 CFR 1910, subpart D. Hand rail construction shall
be.

The hand rail will have one hinged gate with at least 34" clear opening
located above the center of the three-panel door system of 24-ID-B.

**8.2.3.4 Doors.**

The enclosures shall have a combination of both pneumatically actuated
personnel access doors and manually actuated equipment access panels as
shown on the individual enclosure drawings. The personnel access doors
and the equipment access panels shall be physically identical, but the
interlocking and functions are different. Positive stops for full open
and full closed positions shall be provided*.* Table 8.2.5 summarizes
all doors and their placements on a per-enclosure basis.

All doors shall conform to APS Personnel Safety System (PSS)
requirements. All doors associated with 24-BM-A and 24-BM-B must conform
to white beam specifications and therefore must recess in 1.5" deep
trenches in the floor.

The APS PSS Group will supply all required door switches to the
contractor for installation. Their cost will not be charged to this
contract. The door control circuitry will also be supplied by the APS.
The NE-CAT radiation enclosures have single, double, and triple panel
doors (see below and individual enclosure layout drawings for detail).

The contractor shall install all door controls and PSS mounting plates.

White beam BM enclosure doors (24-BM-A & B) must have at least 8 mm lead
thickness.

With the doors in the closed position, the lead cladding must be
designed to prevent x-rays from leaking through. No direct line of sight
will be allowed at the joints. Furthermore, any gap within the
re-entrant door I frame assembly must be less than 1/5 the of the
re-entrant path length. All doors are to be fitted with handles to
facilitate ease of use.

These specifications require conformance to [**APS Document** No.
**410509-00002(H).**]{.underline}

**8.2.3.5 Unistrut Hardware Mountpoints, Labyrinths.**

Included in this specification is the installation of Unistrut channels
on the interior walls and roofs, and on the exterior walls of all
enclosures. These channels will provide support for the cable trays and
utilities.

**Mount Points, Interior walls and roofs.**

Two Unistrut channels should be placed side by side on all wall and roof
panel joints. They should run over the whole length of the panels. In
addition, single channels should be placed 0.15m from either side of
each door opening, with two horizontal channels at heights of 1.4m and
2.5m.

**Mount Points. Exterior walls:**

Unistrut channels should be fixed 0.15m from either side of the panel
joints and station comers. They should extend from a height of 0.2m to
the roof trim on the walls and sections of walls. On the other walls, or
when clashing with doors, guillotine assemblies and other structural
features, they should only extend from a height of 2.1m to the roof
trim.

**Labyrinths:**

The individual layout drawings for each enclosure call out positions for
all roof and side wall labyrinths. As per APS requirements, all side
wall labyrinths mounted above beam level should have the opening
directed upwards, while side wall labyrinths mounted below the beam
level should have the opening directed downwards. Roof labyrinths have
either varying orientations based on need. In the PLAN views of the
layout drawings, roof-mounted labyrinths are rendering in blue. Table
8.2.6 provides a summary of all roof and side-wall mounted labyrinths
for each enclosure. The approximate positions of all labyrinths are
called out in the individual layout drawings.

Both enclosures have specific ventilation or air-conditioning
requirements and corresponding special roof-mounted labyrinths to
accommodate these requirements (rendered in green in the layout
drawings).

The FOE enclosure 24-BM-A has a pair of standard labyrinths that will be
ducted to AC blowers for exchange of the interior air space at room
temperature. Drawing 21-000016-00 shows placement of the control
switches for the AC-blowers (placement indicated by a circled "F",
rendered in magenta).

+---------------+------------------------------------------------------+

The experimental enclosure 24-BM-B has two standard labyrinths that will
be connected via duct work to an air conditioning drop from a nearby APS
air conditioning main. NE-CAT will contract separately for fabrication
of the ductwork and establishment of the connections to the APS air
conditioning system.

**8.2.3.6 Beam Entry, Exit Points and Guillotines.**

Table 8.2.7 lists all beam entry/exit points for the enclosures and
tabulates drawing references and diameter of all penetrations. Table
8.2.7 also indicates that the penetration requires a guillotine
construction. Although the wall penetration permits passage of a
6"diameter flange, the guillotine cutout will be for a 3" diameter
vacuum spool.

**8.2.3.7 Cable Trays.**

12" Wide cable trays shall be installed both on the exterior and the
interior of the enclosures. The exterior installation shall consist of
two layers of trays running along the roof of the enclosures, as shown
in NE-CAT Drawing Number 20-000016-00 (file name external_utility.dwg).
The tray run includes a linear run across the entire length of 24-A and
B connected to the existing 24-ID-A cable trays. The two layers of trays
shall be separated, vertically by approximately 20".

Drawing 21-00015-00 (title: bm_int_cable_trays.dwg) provides PLAN and
ELEVATION views of the 12" wide internal cable trays to be installed
inside each enclosure. Each tray system will consist of two parallel
tray runs separated vertically by at least 6". The lower tray run should
be placed just above the level of the enclosure door margin. The upper
tray must not conflict with the operation of the enclosure crane.
Install a divider in each tray with 4" divider on one side of the
divider (8" on the other).

All cable trays shall be electrically grounded.

**8.2.3.8 Cranes.**

The NE-CAT radiation enclosures shall be equipped with 1 Ton bridge
cranes with manual hoists for equipment handling. The hoist runways
should be leveled in both planes. Mechanical overload protection should
be provided. End stops should be fitted as appropriate. Cranes and
hoists shall be in compliance with the specifications outlined in [APS
Document No. 410509-20002(H).]{.underline}

Drawing 21-000012-00 (bm_crane_layouts.dwg) gives general sector PLAN
and ELEVATION views showing all of the crane configurations. Table 8.2.8
provides a listing of all relevant parameters for the cranes.

All cranes should be mounted as high as possible within the enclosures
to avoid interference with cable tray placements described in the
utilities installation document. Lighting fixtures will be mounted on
the centers of and running parallel to the enclosure roof panels to
provide maximum clearance for the crane tracks.

**8.3.1. Scope**

This document, with accompanying drawings, describes the location,
materials required, and installation of the following list of utilities
and physical improvements to radiation enclosures for the Sector 24-BM
Phase III (bending magnet beam line) build out.

1)  De-ionized cooling water

2)  Compressed air

3)  Electrical (clean and dirty)

4)  Personnel Safety System (PSS)

5)  HVAC

6)  Lighting

An accompanying document entitled "Specifications for the Mechanical
Construction of Radiation Enclosures (Bending Magnet Beamline)"
specifies enclosure layout and configuration, as well as all exterior
additions to said enclosures, including exterior cable tray runs,
utility feed-line mount points, etc.

The contractor is to provide and install all material required to
provide the utilities described in the assembly drawings listed in Table
II. These utilities include installations both inside and outside the
enclosures as shown on the drawings. APS is to provide the points where
the required utilities shall be connected to house services.

Unistrut supporting members for utilities installation have been
included in the enclosure construction specifications and drawings.
However, if the utility subcontractors identify needs for additional
Unistrut to be welded to the enclosures they must enlist the efforts of
the enclosure contractor to make such additions.

All installations shall be performed in accord with APS installation and
safety requirements, specifically following the requirements contained
in Document No. 410509-00002 "Technical Specifications for APS Beamline
First Optics, White and Monochromatic Beam Experimental Enclosures
(April13, 2003)".

The NE-CAT Sector (APS Sector 24) is based upon the tandem-offset
undulator concept and will produce up to 4 beamlines, the first three
commissioned in 3 phases:

**Phase Beamline Description**

I Broadly tunable ID beamline utilizing the "upstream" undulator.

II Narrow tunable ID beamline + fixed energy sidestation utilizing

> the "downstream" undulator.

III Bending magnet beamline.

The overall sector layout is shown on NE-CAT Drawing:

Number: **20-000010-00 "NE-CAT General Layout"**

**8.3.3. Cooling Water.**

Chilled, de-ionized cooling water (feeds and returns) shall be installed
as below and per drawing. Chilled, de-ionized water supply and return
lines (2" diameter schedule 10 stainless steel pipe) are to be fed from
the central feed lines running the length of the beamline, supported by
an inboard support system (see drawing number 20-000014-00, filename:
bm_air_water_distribution.dwg) and into the enclosures through the
labyrinths as designated in the enclosure utilities drawings. In drawing
21-000014-00 one feed-through labyrinth per hutch is indicated to
identify the designated labyrinth.

APS will provide access to a centralized chilled, filtered, de-ionized
pressurized feed. The contractor shall follow appropriate plumbing
discipline and APS requirements so as not to cause electrochemical
problems for the APS water source involved (i.e. all stainless steel and
copper construction throughout the sector 24 cooling loop). All
in-enclosure plumbing runs will be constructed from 0.75" 304 stainless
steel tubing, using 304 stainless steel ball-valve terminations.

A ball shut off valve shall be installed from the main header for both
the supply and return lines of the chilled water for all enclosures. In
the case of both chilled and de-ionized water one (1) inch lines should
be used downstream of the shut off valves.

After entering the enclosures, the chilled water lines shall follow the
course shown in each enclosure utility drawing, with all piping located
on the inboard wall. Source lines are placed at an elevation of
approximately 23" relative to the floor. Return lines run parallel to
source lines at an elevation of approximately 15". In some cases feed
and return lines need to be routed around a door margin. Drawing number
21-000014-00 (filename: bm_air_water_distribution.dwg) provides an
aggregate floor plan showing the placement of all feed-return
terminations per enclosure. In this drawing a circled "W" (rendered in
green) is used to note the approximate placement of a stainless steel
ball-valve termination pair (feed and return). Furthermore, due to space
limitations all plumbing runs in 24-BM-A must be as close to the inboard
wall as possible (use minimal standoffs for tubing wall mounts).

**8.3.4. Compressed Air.**

The compressed air line shall be 0.5" diameter copper tubing with
soldered joints. The main distribution will run parallel to the cooling
water feeds on the inboard hand rail-utilities support as shown in
Drawing 21000014-00. The source line shall run from the compressed air
supply line near Column 137 and continue the entire length of the
beamline upstream to enclosure 24-BM-A and 24-BM-B for entry through the
designated labyrinth. In addition to feeding the interior of the
enclosures through the labyrinths the compressed air shall be supplied
to the door control boxes for both enclosures. Each termination shall
consist of an appropriate ball-valve.

Drawing 21-000014-00 (filename: bm_air_water_distribution.dwg) shows an
aggregate plan view for compressed air distribution. Each termination is
shown as a circled "A", rendered in red. Compressed air feeds enter each
enclosure using the same labyrinth used for water and electrical
penetration. Within the enclosure compressed air feeds are run at
approximately 66" elevation from the floor on the inboard wall.

**8.3.5. Electrical**

All installed electrical services shall meet the requirements of the
national Electric Code and ANL requirements.

Main electrical distribution shall use an inboard support system for
support and routing. Conduits must be run above all possible sources of
water leakage or condensation (i.e. above the cooling water and liquid
nitrogen distribution lines).

**8.3.5.1 Lighting.**

Install fluorescent lighting fixtures on the interiors of the roof
panels of all enclosures per standard enclosure interior lighting.
Lighting fixtures should be mounted in middle of the enclosure panels
(rather than the joins), in order to recess them as far as possible from
the crane tracks, that will be mounted in all enclosures. Placement of
the three-way lighting switches is indicated for all enclosures in
Drawing 21-000013-00, indicated by a circled-"L", rendered in magenta.

**8.3.5.2 Interior Enclosure AC Distribution.**

Clean and dirty AC mains will enter each enclosure using the designated
feed-through labyrinth (indicated in each enclosure's utility drawing).
The contractor must provide NE-CAT with drawings detailing internal
distribution conduits runs for each enclosure prior to beginning any
work, so that we may confirm that said conduits will not interfere with
the operation of enclosure rail cranes.

Clean AC distribution shall run at an elevation of approximately 86"
relative to the floor in enclosure 24-BM-A.. In the experimental
enclosure 24-BM-B clean power distribution and outlet boxes should be
situated at an elevation of 50" relative to the floor. Dirty AC shall
run at an elevation of 15" from the floor where there is no conflict
with cooling water runs. The contractor shall use white receptacles for
clean power and brown receptacles for dirty power. In case there is a
conflict with cooling water line placement, dirty AC distribution should
be placed at a convenient height, ABOVE the water distribution lines.
Both clean and dirty AC termination will be in the form of 4-way
outlets. Refer to drawing number 21-000013-00
(filename:bm_power_distribution.dwg) for approximate placement of
interior and exterior AC terminations. In both BM enclosures, AC
distribution boxes should never be mounted on the enclosure panel joins
(i.e. recess the distribution boxes as much as feasible). In drawing
21-000013-00 a clean 4-way outlet is denoted by a green circled "C" and
a dirty four-way outlet is shown as a blue circled "D".

**8.3.5.3 Circuit Breaker Panels.**

All circuit breaker panels shall have main breakers. No GFCI breakers
are to be used in any panels. All circuit breakers situated within a
breaker panel should service outlets in the same enclosure (i.e. do not
mix circuits for different enclosures within a single breaker panel
panels). All breaker panels will be mounted on the inboard wall of
enclosure 24-ID-C. Drawing 20-000013-00 shows the placement of the
"clean" and "dirty" circuit breaker panels for all BM enclosures.

Four new panels shall be provided for 24-BM-A&B and shall be designated
as follows::

TRPC-X15-7-24-BM-A to be fed from TRPC-X15-7 ckts 7,9,11

TRP-X1-7-24-BM-A to be fed from TRP-X1-7 ckts 25,27,29

TRPC-X15-7-24-BM-B to be fed from TRPC-X15-7 ckts 13,15,17

TRP-X1-7-24-BM-B to be fed from TRP-X1-7 ckts 26,28,30

**8.3.6. Personnel Safety System.**

The PSS shall be installed in accordance with the document entitled
\"Statement of Work for Typical Personnel Safety System Installation.\"
Drawing 20-000015-01 (file name:pss_equipment.dwg) shows the locations
of all interior and external PSS controls, boxes, buttons, and boxes as
well as the PSS wireways. The position of the single external PSS panel
controlling both 24-BM-A and 24-BM-B is shown in Drawings 20-000010-00
(file name: general_layout.dwg) and 20-000015-00 ( file name:
pss_equipment.dwg). The PSS panel box shall not encroach upon the egress
aisle.

**8.3.7. Vendor Responsibilities.**

**8.3.7.1 Labeling and Documentation**

The contractor shall affix labels to all circuit boxes showing the
circuit number and location of the circuit breaker. Each circuit breaker
panel shall be properly labeled following the standard used for 24-ID
panels. The exterior of each panel shall be labeled by panel number and
circuits serviced. Documentation within the breaker panel shall clearly
indicate the supply of each breaker. On the water cooling lines, the
contractor shall affix labels indicating supply and return piping. The
vendor shall provide NE-CAT with copies of all relevant drawings, part
lists, and manuals required for NE-CAT's use in operations and
maintenance of the utilities.

**8.37.2 Certification.**

The contractor shall provide certification that all work has been
performed in conformance to [APS Document No. 410509-00002]{.underline}
and in conformance with APS and Laboratory workmanship and safety
requirements.

**8.3.7.3 Training.**

The vendor\'s installation staff shall be trained according to the APS
and other applicable safety regulations before starting work on site.

**8.3.8. Acceptance Criteria.**

Acceptance criteria shall follow the [APS Document No.
410509-00002).]{.underline} NE-CAT and the APS reserve the right to
final inspection upon completion of the installation before acceptance.
This includes, but is not limited to, demonstration of proper
functioning of installed utilities, inspection for proper labeling of
all installed components, inspection of clean up following completion of
installations, etc.
