Beam restore after RF worka

Log Number: 4130376Logbook(s): Entry Makers: carlinoBody: 

Sent upto 60 uA to Hall C. Beam upto 50 uA runs without problems. Above 55 uA limited by 8E02 BLM trips. Relative orbits through the machine match ZPOS from 08feb2023 23:22:58 with C beam.
Hall C @ 8E04 5.0. Hall A beam @ 11.6.
Relative orbits through the machine match ZPOS from 08feb2023 23:22:58 with A beam with minor orbital difference in 4R, but nominally the same throught he rest of the machine.
45 uA to Hall A without trips.
Lambertson Viewer was almost unusable. No sure if the camera is fried or what. No wires visible. Barely can see beam.
