ILC New Muon Test Facility Meeting Minutes

9-1-06

by Ralph Pasquinelli

A Kickoff meeting was held on Friday September 1 to organize the efforts
for building the ILC test string at the New Muon Facility at Fermilab.
While this meeting is intended to concentrate on the RF systems for the
complex, clearly many support systems are symbiotic and tied into the RF
systems. For this reason, the meeting is open to all participants in the
project ranging from cryogenics, controls, mechanical and layout,
instrumentation, and cryo module fabrication.

Sergei Nagaitsev made a brief presentation on the parameters for the
test string and layout of the facility. His presentation is available at

Ralph Pasquinelli will be collecting details for a schedule that would
hopefully provide the first RF system by summer of 2007. Harry Carter
indicated the first cryo module is coming in kit form from DESY. He
estimates a four-month period of assembly once receiving the parts. The
current estimate is to deliver a completed cryo module to the New Muon
facility by July 1, 2007. Arkadiy Klebaner is leading the cryogenics
effort and is working on a schedule for completion of the cryo plumbing
for the first cryo module. Arkadiy does not believe it is possible to
have a functional system by the July 1 date. There are a series of RF
tests that must be performed warm. Timing the commissioning of the RF
hardware to this tentative receipt date would allow these warm
measurements to proceeds as work continues on the cryogenics.

A system block diagram will be created to clarify how the parts of the
system are integrated. This is especially important in understanding the
complexity of the control system.

Jerry Leibfritz is responsible for the mechanical details of the
facility. He will be taking over the responsibility for the layout of
the facility from Paul Czarapata and make this drawing public.

The test facility will be supported by other parts of the ILC
collaboration from Argonne and SLAC. Argonne is working on the local RF
distribution, which will be required as more RF systems are added. SLAC
will be providing 10 Mwatt klystrons, RF distribution hardware, and cryo
couplers when the second cryo module is delivered in 2008. By the end of
2009, an operational three cryo module RF system, electron gun, and
capture cavities with beam are the goals.

Over the next few weeks, details will be assembled and an agenda for the
next meeting will be distributed. If there are questions or details or
names of people who should be on the mailing list, please forward this
information to Ralph Pasquinelli at pasquin@fnal.gov

The intention is to hold these meetings at two-week intervals on Friday
mornings at 10:30 AM in One West of Wilson Hall. The next meeting is
planned for Friday September 22.

Comments from Sergei Nagaitsev:

Ralph,

 

I have several comments for your ILC New Muon test minutes 9-1-06

 

1. The name of the facility will be the NML Facility.  The ILC program
is going to be the first customer.  Your minutes should be called \"NML
RF Systems meeting\".  I will use your meeting time slot to have
meetings on other systems: beamline layout, beam sources, dumps, magnets
etc.

 

2\. I see Jerry\'s and Paul\'s roles as follows:  Paul Czarapata is
responsible for getting the beneficial occupancy of the NML building. 
He has the signature authority over several task codes for the cyclotron
magnet removal, clean up and filling the hole.  I might also ask him to
oversee the utilities upgrade.  Jerry Leibfritz will be responsible for
the mechanical installation of the accelerator, part of which is the
first cryomodule.  He receives the cryomodule from the TD and installs
it at the NML.  Jerry is now collecting inputs from various systems
regarding the layout of the accelerator.

 

3\. It is my recollection that SLAC is supposed to provide rf
distribution system for the 1st cryomodule in the summer of 2007 (not
2008).

 

4\. Finally, Brian Chase recommended that we should talk to CC2 folks
(Helen) to see if we can join the meetings with them.

 

Thanks,

Sergei
