2. February 2002Steve Geer2 WELCOME to the MUCOOL & MICE MEETINGS

3. February 2002Steve Geer3 EXISTING MUCOOL MISSION STATEMENT Design, prototype, & bench-test all cooling channel components & eventually test a cooling section in a muon beam DRAFT REVISED MUCOOL MISSION STATEMENT Design, prototype, & bench-test all cooling channel components & make an engineering beam-test of a cooling section The emergence of MICE has an impact on the mission of MUCOOL

7. February 2002Steve Geer7 The MUTAC Report Says: “Ionization cooling remains the primary R&D issue for the collaboration. The most difficult part is the develop- ment and integration of the hardware, which is the goal of the MUCOOL efforts.”

8. February 2002Steve Geer8 Why is MUCOOL so Challenging ? We need to be able to operate a system in which Liquid Hydrogen is separated by a baking foil from an ignition source containing the energy of 10,000 light bulbs, and all of this is within a system of SC solenoids that might quench from time-to-time. The system must operate as 10 12 charged particles pass, & WE NEED TO GET SAFETY APPROVAL. We need to understand high gradient NCRF Cavity operation in Multi-Tesla magnetic fields, going well beyond the current state-of-the-art. We must understand and solve our present cavity breakdown problems.

9. February 2002Steve Geer9 Status in December 2002 ? 201 MHz Cavity Designed 805 MHz R&D Ongoing 201 MHz Cavity Construction Begun ? Cavity Solenoid Design Begun ? 805 MHz and/or 201 MHz test system installation about to begin ? Absorber filling systems installation about to begin First Absorber Test Setup Designed – Safety Process Advanced
