Current Status

On the accelerator side:

• Hall C in the middle of switch to 4 pass

--> Wien angle to -39.2

• Beam studies on Thursday (delivery to Hall A dump)

On the Hall side:

• Some HCal voltage set points got set to zero

--> Now has an alarm if at 0 V even if setpoint is zero

• Detectors and DAQ seem to be working well (SBS GEMs in much better shape)

• Production running at 17 uA overnight maximized trigger rates

--> Could be pushing the front track too hard

--> Might need to back down with the current

• Production running until they make us stop

--> Wien change - how do we want to handle this?

GEN-RP KLL run plans
