From MTA website: “Pillbox cavity run plan (Be buttons)”

1 Commission the cavity to 40MV/m with flat Cu (TiN

coated) with B=0. Run for 5 X 105 pulses.

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.
