Shift crew: F. Benmokhtar, Y. Ilieva, X. Qian-4:20pm P0 Left set to -5:25pm Beam went off, MCC is saying that there is a safety system trip
that they need to investigate this. -6:10pm: Called MCC for an update, there is an RF problem in teh south Linac. This will take a while to repair. -6:50pm: Beam back -9:40pm: Inserted S0, downloaded the S0 trigger, increaded the cuurent to 10mu, set Ps4 =17, Ps3=20 and Ps6=5 -11:20pm: Switched to P0=0.4666 GeV/c
