ilc s2 recommendation
ILC S2 recommendation
  • ILC S2 task force (string test definition) recommends: the minimum size system test needed to confirm the performance of a new design is a single RF unit with ILC like beam.
    • ILC RF unit is 3 CMs powered by a 10 MW MBK
  • Many tests are statistical in nature, a longer string test with several RF units would be better.

fermilab cryomodule plan
Fermilab cryomodule plan
  • 1st Cryomodule (2007)
    • Assemble a TESLA TTF type III CM from DESY “kit”
    • Cavities built and fully tested by DESY
  • 2nd Cryomodule (2008)
    • Also TTF type III cryomodule
    • Cavities are processed and tested in the US
    • Electropolished and tested at JLAB, Cornell, and ANL/FNAL
    • Cryostat and cold mass from Zanon in Europe
  • 3rd Cryomodule (2009)
    • 1st type IV ILC cryomodule built anywhere
    • Parts built in U.S. industry
  • 4th-6th Cryomodules (2010-11)
    • Build ILC RF unit in U.S.
    • Transfer knowledge gained to Industry

NML
  • NML is a facility to be located in the existing building at Fermilab (New Muon Lab)
  • New Muon Lab building is part of Fermilab’s ILC Test Areas (ILCTA_NM)
    • Other areas are: MDB (horizontal SCRF cavity test stand), IB1 (vertical test stand) etc.
  • The first NML user will be the ILC program.
    • The cryomodule tests are also essential to Project X (β=1)
    • The Accelerator R&D (AARD) portion will first piggy-back on these programs; its share will increase with time

fermilab nml plans
Fermilab NML plans
  • Phase-1 (FY07 - FY08)
    • Prepare Facility for Testing of First Cryomodule (CM1) without Beam
      • Infrastructure, RF Power, controls
      • Cryogenics (Refrigerator #1) => reuse of existing TeV refrigerator
  • Phase-2 & 3 (FY08 - FY10)
    • Install Gun, Injector, CM2 and CM3, Test with Beam
      • New RF Gun
      • Move A0 Photo-Injector to NML and Install Test Beamlines
      • Extend Building to fit Third Cryomodule
      • Cryogenics (Refrigerator #2 )
      • Upgrade RF System to 10 MW
  • FY11 and beyond run ILC RF unit with full ILC parameters
  • Concern: to run at 5 Hz need a new cryoplant (300 W at 2K). Money for it is not in FY08 or in FY09??. Two year lead time.

nml building extension
NML building extension
  • Began Design of NML Extension with CF&S Group (FESS)
  • Room for 6 Cryomodules (2 RF Units)
  • Expanded Diagnostic and AARD Test Area
  • Cryoplant (300W)
  • Possible 2-Tunnel Design to Mock-up ILC Design

nml summary
NML summary
  • NML is being constructed to address the ILC S2 R&D list, to test ILC baseline and alternative components, and to conduct AARD.
    • The A0 photoinjector will be part of the NML facility
  • Progress is resource limited
    • FY07: 4.9M$ (M&S direct), 40 FTE’s
    • FY08: anticipate similar resources
  • Collaborations:
    • SLAC will supply RF distribution system. May be a model for Project X.
    • ANL, DESY, KEK, INFN
  • Already have 2 graduate students in accelerator physics working on NML design.
  • AARD program is still developing
    • Had a workshop in Nov 2006 to “gauge” outside interest
