  1. NewMuon Lab: RF kick-off meeting Sergei Nagaitsev (Fermilab) Sep 1, 2006

  2. ILC-like beam parameters • GOAL for NewMuon Lab: Assemble, commission and operate ONE ILC rf unit (three cryomodules) at ILC-like beam parameters • Accel. gradient ~ 30 MV/m • # Electrons/bunch 2×1010 • # bunches/train 2820 • Bunch rep. rate 3 MHz • Train rep. rate 5 Hz • Ave. current ~ 50 µA • Beam energy and average beam power:One CM, 250 MeV, 12 kWTwo CM's, 500 MeV, 25 kWThree CM's, 750 MeV, 40 kW NM Layout Options Sergei Nagaitsev, 8/28/06

  3. ILC Plans for NewMuon beam 1. Demonstrate stable long-term high-gradient beam operation at ILC-like bunch parameters.2. While operating at high gradient and ILC-like beam currents, demonstrate a LLRF controls system such that the beam energy and beam phase stability meet the ILC specs.3. Evaluate effects of cavity gradient spreads, dark current, cryogenic load, radiation levels with beam operation.4. Measure beam kicks due to couplers, cavity tilt, quad rotations + tilt errors characterize focusing properties of SCRF cavities.5. Measure vibrations of cavities and quads.6. Test beam diagnostics. NM Layout Options Sergei Nagaitsev, 8/28/06

  4. AD/TD RF Responsibilities (within the Fermilab ILC program) • Overall AD RF Leadership – Ralph Pasquinelli • Overall TD RF Leadership – TBD NM Layout Options Sergei Nagaitsev, 8/28/06

  5. Stage 1: a single cryomodule • July 1, 2007: Cryomodule delivered by TD to NewMuon • First several months: cryo and rf system integration • SLAC provides some rf distribution components • Fermilab provides HLRF (5 MW Klystron) and LLRF systems • Coupler conditioning • RF injector to supply beam in Dec. 2007 • Rf gun (requires 5 MW Klystron) • Two capture cavities NM Layout Options Sergei Nagaitsev, 8/28/06

  6. Stage 2: two cryomodules (summer 2008) • Mid 2008 - two CM's, 500 MeV, 25 kW beam power NM Layout Options Sergei Nagaitsev, 8/28/06
