## Beamline layout

## FOE Layout

**White beam enclosure**
**Front end exit window and collimator****	**
**Beam defining apertures – L5 slits  ****	**
**Be Compound Refractive Lens**
- Collimates the white beam for HERIX
**High heat load monochromator**
- Kohzu Double crystal monochromator
- Beam offset variable from 22 to 35 mm
*Planned for 22 mm operation*
- Diamond water cooled crystals
**Integral shutter P5-80 – modified P5-70****	**
- White beam stop (Bremsstrahlung and photon beams)
- Monochromatic shutters for MERIX station

## White Beam Components

## Beam Defining Apertures

**Design Experiences from XOR 3-ID White Beam Slits**
**Capable of handling higher heat loads**

## Be Compound Refractive Lens

**Based on design experiences from XOR 3-ID White Beam ****Compound Refractive Lens **

## Integral Shutter

## Integral Shutter

**New White Beam Stop**

## MERIX Station

**Monochromatic station**
**Houses monochromatic optics and for MERIX Experiments**
**Medium / High resolution monochromator****	****	**
**K-B Mirrors for MERIX****	****	****	****	**
**MERIX instrument – 8 circle diffractometer****	**
**Monochromatic shutters P8-60 with large vertical opening for HERIX station. Existing APS standard component****	****	**

## HERIX Station

**Monochromatic station**
**Dedicated for HERIX experiments**
**K-B mirrors for HERIX****	**
**HERIX spectrometer****	****	**

## Work Area

**Enclosed work area attached to MERIX and HERIX stations**
**Access to MERIX and HERIX station from work area only**
**Provides a quite and pleasant work enviornment**
**Provides better temperature stability for MERIX and HERIX stations**
**Access to control system equipment from within the work area **
**All control system equipment installed within the 5 racks provided with access from work area enclosure****	**

## Utilities

**Power:**
- Beamline powered by 2 30 KVA transformers for Clean and Utility power
- Each station equipped with numerous 110 AC 20A in both Clean and Utility power circuits
- HERIX station has 3 phase 220V 30A & 40A circuits
- MERIX station has 3 phase 220V 30A circuits
**Water:**
- 40 GPM @ 100 PSI De-ionized water provided by APS
*10 GPM each is available in HERIX and MERIX stations*
- 10 GPM Chilled water provided by APS
*3 GPM each available in MERIX and HERIX Stations*

## Utilities

**Air**
- 90 PSI provided by APS
*Available inside stations to drive users equipments *
**Vacuum**
- Rough vacuum for whole beamline  *10**-3**~ 10**-5** Torr*
*Access in each station for user equipments*
**Work on Utility layout carried out in consultation:**
- ASD Electrical Systems
- ASD Mechanical Engineering
- ASD Vacuum Group
- AOD Conventional Facilities

## Utility Layout

## Safety Systems

**Personal Safety System**
- The next generation PSS system will be installed
- APS used IXS beamline as prototype
- Employs touch screen interface for Human Interactions
- All information about the PSS will be available for the beamline control system via EPICS
**Beamline Equipment Protection System**
- Specifications provided by IXS design team
- Designed and maintained by ASD Safety Interlocks group
- Employs PLC hardware similar to PSS system
- Has touch screen interface for Human Interactions
- Has EPICS interface to beamline controls

## Computing

**Computing and Network**
- Beamline equipped with Gigabit network infrastructure
- Tied to APS network via dual redundant fiber optics network
- MERIX and HERIX stations instrumented with network outlets
- Work Area provided with plenty of network outlets
- Huge data storage in XOR servers
- Seamless integration with APS computer systems
- Wi-Fi provided with VPN access  to beamline for laptops
- All computing and network infrastructure installed and maintained  by AOD Information Technology group

## Beamline Controls

**Beamline Controls will be based on EPICS**
- Supported by AOD Beamline Controls group
- Use VME-64 based hardware
- Employs 4 VME crates with MV5100 processor
- User OMS VME based motor controllers and Phitron motor drivers with 4 phase stepping motors for motion control
- Workstations are SUN blades with dual processors and large memory
- Provide numerous interfaces
