  1. MuCool Test AreaRF Workshop Derun Li Center for Beam Physics Lawrence Berkeley National Laboratory November 15, 2010

  2. MAP RF Goals Develop a workable solution for high gradient NCRF operating in B fields between approximately 3 and 6 T. Support sub-assembly prototyping for the 6D cooling bench test. • Guggenheim • FOFO Snake • HCC MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  3. Workshop Goals • Review the status of the MTA RF programs • Review proposed future RF programs • Discuss RF R&D strategy to respond to the comments and recommendations from the MAP Review in August 2010 • Scope of the work of MAP RF proposal • Resources • Schedule and milestones • Concerns/Risks MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  4. Current RF Programs • Targeted R&D programs to understand the RF breakdown problems in magnetic fields  a workable solution • Physics models and numerical simulations, • Experimental programs and new techniquesat 805 and 201 MHz • Box cavity to study E x B effects • Magnetic field insulated cavity • Physics model to understand RF • breakdown in magnetic fields • The 805-MHz with RF buttons • High pressure cavity • ALD to eliminate field emission • Be wall cavity MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  5. Future RF Programs • Magnetically insulated box cavity • Beam test of HPRF cavity • The 805-MHz RF button tests (Be) • Update design of 805-MHz cavity • Dielectric loaded cavity • Design and fabrication of Be-wall cavity • ALD processed buttons in pillbox cavity • 201-MHz cavity test with coupling coil magnet at MTA • Complete MICE 201-MHz cavity • Single cavity vessel MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  6. Comments from the MAP Review More cavities and tests International RF Workshop MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  7. Comments from the MAP Review Concerns on beryllium MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  8. RF Recommendations from MAP Review MTA RF Workshop, D. Li, Lawrence Berkeley National Lab, November 15, 2010

  9. In respond to the MAP Review • Update RF proposal • Revisit previous plans + this WS • Schedules and milestones • Exploring more RF tests in magnetic fields • Design and build more cavities + RF tests • SLAC group: 2-T SC magnet and tests at s- or x-band frequencies • International workshop on high-gradient RF cavities • Wish we have a productive workshop MTA RF Workshop, D.
