Hardware commissioning task covers the US participation in LHC
commissioning beyond the US hardware deliverables. There are two
subtasks: 1) direct participation in the LHC Hardware Commissioning
program. 2) development of a measurement system to measure rapidly
changing magnetic fields for LHC accelerator magnets.

For subtask 1, cost is largely travel and moving expenses for all
hardware and IR long term hardware commissioners, with some effort for
project oversight. Note that the level of support for relocation was
increased by \~\$7K/ traveler/round trip to make the level of support
more in line with LHC detector relocations. Salaries for long term
hardware commissioners are covered by the home institutions. (the
exception to this is when commissioners are working on IR commissioning,
where some of the salaries are covered in task 31.1.2.1.2). CERN will
provide a supplement while commissioners have Paid CERN project
associates status. This status will be granted for all long term
commissioners. The exception is that LARP will pay for two months of
cost of living expenses for LBNL engineer, Frederic Gicquel, who will
work at CERN preparing for hardware commissioning, prior to accepting a
project associate position.

For subtask 2, cost is Labor (0.4 FTE) and travel expenses for two round
trips to CERN. CERN will pay project associate supplement and one round
trip ticket.

**Milestones for Machine Hardware Commissioning Subtask I**

1\) November 2006 First \"long term commissioner\" sent to CERN

2\) January 2006. Completed list of US Candidates to Participate in
Hardware Commissioning

3\) January 2006. Completed Collaboration Agreement Between Fermilab and
CERN

4\) April 2006. Definite dates for Fermilab long term commissioners

5\) September 2006 Send second group "long term" hardware commissioner

Begin commissioning of first IR

6\) January 2007 Decide when to send any additional HC commissioners

7\) End of CY 2007 LHC commissioned to injection energies, first
collisions at injection energies

8\) Summer 2008 LHC commissioned at full collision energies

**FY2007 Milestones for Measurement system:**

-   Q2 -- Develop hardware, software specifications for CERN system

-   Q3 -- Complete system for measuring fast-pulsed magnets

-   Q4 -- Complete initial test of system

**Statement of work for current FY 07:**

LARP Involvement in Hardware Commissioning:

In the fall of 2004, CERN issued a document outlining the shortage of
skilled personnel to complete the hardware commissioning task ( See:
Management Report on Resources for Hardware Commissioning, LHC Project
Document LHC-PM-MR-0002 rev 1.0) The document showed that CERN would be
short approximately 50 engineers and scientist for the 14 month duration
task.

In response to this need and with the realization that this
participation could be of benefit to the US HEP program, a task force
was formed in February 2005. The results of this task force were
published in July 2005. The report concluded that personnel would be
available from the US laboratories.

Fermilab management has agreed to supply \~6 FTE staff, with the
understanding that they will receive project associate at CERN. Thus
LARP will be required to support relocation expenses and possibly other
incidental expenses during their stay. Some salary will be covered by
LARP when working on IR commissioning (see task 31.1.2.1.2)

Based on our recruitment effort, we expect 3 people from Fermilab to go
to CERN in late FY06 or early FY07. In FY2007 negotiations are well
underway to send 2 additional people. With the delay in commissioning
startup, these two people will likely go to CERN in the middle to end of
FY07. As for LBNL, negotiations are well advanced for sending two people
from LBNL in FY07. The present plan is to send Frederic Gicquel in
November 2006. The first two months will be cryogenic training, with a
"formal" project associate status starting in January 2007. Joseph
Rasson will start working at CERN in January 2007, spending ½ of his
time working on IR commissioning.

Through these long term commissioners, LARP will play an active role
throughout the entire LHC hardware commissioning, which is estimated to
be expend well into CY2008.

Oversight:

A fraction of an FTE is reserved for planning for overseeing effort and
planning for 2007.

**Statement of work for fast-changing magnetic field systems:**

CERN (Luca Bottura) has requested the help of BNL (Animesh Jain) to
build a measurement system that will precisely measure fast-changing
magnetic fields. This is a major issue for LHC at injection. Luca
Bottura is spearheading the software simulation of the magnets. The
rapid field measurements are intended to benchmark the simulation. Over
the period of the last several years, BNL has built and debugged a
system for making such measurements on the fast-pulsed model dipole that
we built for GSI. This system will be the starting point for the CERN
system. At present, it is estimated that three stays of one month, plus
work from BNL (0.4 FTE total), beginning early in CY07, would be needed
to build and commission such a system at CERN. Lodging expenses would be
paid by CERN through a six-month appointment as Project Associate. LARP
would pay for two round trips.

FY2008 plan:

Finish Hardware commissioning of machine (estimated completion date:
Summer 2008)

Measurement of a representative number of LHC magnets.
