EXISTING MUCOOL MISSION STATEMENTDesign, prototype, & bench-test all cooling channel components

& eventually test a cooling section in a muon beam

DRAFT REVISED MUCOOL MISSION STATEMENTDesign, prototype, & bench-test all cooling channel components

& make an engineering beam-test of a cooling section

The MUTAC Report Says: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.”

Why is MUCOOL so Challenging ?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 1012 charged particles pass, & WE NEED TO GET SAFETY APPROVAL.

We need to understand high gradient NCRF Cavity operationin Multi-Tesla magnetic fields, going well beyond the current state-of-the-art. We must understand and solve our present cavity breakdown problems.
