Hall A Cavity BPMs ..... ** Late Entry **
9/25/23
PM
Activated/calibrated the 3 cavity BPMs ('1H04B, C, and D) for possible utility with the ongoing BCM measurements for Hall A folks (is this plural for folk, which is also plural??). The first whack was done parasitically, so isn't perfect, but is usable. If more accuracy is preferred, then dedicated beam time may be necessary.
Settings are shown in the Expert Screens.
