  8. From MTA website: “Pillbox cavity run plan (Be buttons)” MTA-RF: Fabrication Readiness Review 1 Commission the cavity to 40MV/m with flat Cu (TiN Review coated) with B=0. Run for 5 X 105 pulses. Daniel Bowring 2 Assuming success for #1, set B=2T and slowly raise RF gradient. If sparking occurs before 15MV/m stop. If 15MV/m is reached, run for 104 pulses @ 2T and 15MV/m and consider commissioning complete. Automation program will be used with gradient set point of 15 MV/m. 3 . . . Measurements with B > 0 start at 2.5 T, decrease in 0.5 T steps. More detail might be useful for the experimental design.
