Didn't grab screenshot of pathlength before correction. It wasn't awful, but a couple of the higher passes were just out of spec.

1L12 not going to HV upon beam permit. Found CPS fan off and 3 ac fuses keeping it out of HV enable. Closed all back up and in HV and half an hour later cav. 4 kly. resistor blew and no KCCU. Replaced resistor and restored zone to RF. Resistor and RF restore by RF guru Larry the RF Man and thanks to Ben for getting substance (pizza) to give us the needed energy to get another shift in and beam going. L. Farrish and C. Kerns.
