The B laser reconfiguration work is complete. But the IA WP work needs will be done tomorrow due to the smaller dimension of the new (1/10) WPs, which don't fit into the existing mounts. Adaptors will be ready in the morning.

We started flowing gas after the SRF 8:30 meeting and finished processing cavities 1, 3, 5, and 7. We started processing cavities 2, 4, 6 and 8. We will complete processing cavities 2, 4, 6 and 8 tomorrow with the plan of leaving the system pumping on the plasma processing turbo cart. We will resume processing on Monday with a plan of having the system on ion pumps ready to turn over to the SRF vacuum folks on Wed. morning.

At the end of the shift. We secured the RF and turned off the amplifiers. We closed off the gas supply valve at the cavity gas supply* valve.

Gun bake progressing well

Temperature of gun chamber lagging setpoint - I plugged in the third heater bar to help achieve temperature, and reduced the temperature goal for today to 200 from the original 250. I'll ramp to 250 tomorrow while watching.

Pressures continue to be good (pump cart 10^-6 Torr) with chamber and NEG tube about 170C.
NEG tube now controlled on two different controllers- the heat tapes weren't heating evenly between the upstream and downstream sections. These will continue to ramp to 250C overnight. Valves holding steady around 90C.
