Smooth runing, runs 2605-2609 are good, the (9th run) 6207 is junk.

Raised L15, L21 and R24 voltages to 3850V from 3800V. L14 is the only voltage below 3850V and it was left at 3800V so as not to provoke it.

Voltage change occured between runs, before 6206. Immediately, L21 and R24 tripped. Sense and field wire tripped on R24. I set it to STDBY then OPER and now things are quiet again.smoth runing, few wire chamber trips,

As L21 sense and R24 field&sense were tripping repeatedly at -3850V, I reduced these to -3800V. L14 was already at -3800V, L15 is at -3850V.
runing between 120 and 80 mA.

WC L14 is still at 3800.

Crunching all runs.

Ben noticed that the HV on L21 and L24 were low [3800] (probably after a HV gui reboot last night], raised them to 3850m started to get some trips,
