  1. New Muon Lab SCRF Test Facility Sergei Nagaitsev Oct 15, 2007

  2. 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. Nagaitsev

  3. Rough S2 Schedule Nagaitsev

  4. 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 Nagaitsev

  5. 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 Nagaitsev

  6. 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. Nagaitsev

  7. Phase-1 Layout of NML Capture Cavity 2 (CC2) Cryomodule-1 (CM1) (Type III+) CC2 RF System 5 MW RF System for CM1 Nagaitsev

  8. Overall layout of New Muon Lab Capture Cavity 1 (CC1) Cryomodules RF Gun CC2 Gun RF System CC1 & CC2 RF 5MW RF System for Cryomodules Space for 10 MW RF System Nagaitsev

  9. 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 Nagaitsev

  11. 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 Nagaitsev
