With Gun HV OFF, checked connections in ISB. Measured V_Monitor = +1.000 V corresponding to +1000 V applied voltage to the anode. All seems fine. Next MD, will check in Tunnel.

No findings on 1L09-1or -7 as far as torque number. 2L05-5 had very small torque value at 10 turns clockwise (probably tuning cavity at that amount of turns), value was 2-3in/lbs. Returned all 3 to where I started position wise.

Didn't look too much into while restoring the machine until Hall B started taking 250nA production. I noticed that the gun is pushing ~18uA to make it along with Hall B's attenuator being fairly high. Looked into it and the orbit did not come back perfectly on the Rels for whatever reason. when comparing it to around this time last night the gun was using ~9.5uA to make the same current and the master slit interception readback was about half what it currently is. The attenuator now is 80-100 more than it was last night.
