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.

Rough S2 Schedule

Nagaitsev


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
