Completed second round of plasma processing 1L07-2,4,6 and 8. started 1L07-1,3,5 and 7, will be completed tomorrow.

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. (* 1/4" valve) just upstream of the gas supply manifold which is connected to the right angle valve on VIP1L08A. We pumped out the gas supply cart between the outputs of the MFCs and the input to the cavity gas supply valve using the scroll pump on the gas supply cart.

The long-awaited CED System Reference is finally here! https://acgdocs.acc.jlab.org/en/Staff/ced_system_reference

There have always been questions about what properties need to be configured for the different systems in CED, what the values mean, and what changing them actually does. This is intended to put those answers in one place.
It’s working documentation, so if something looks wrong, is unclear, or I missed something, please ask/comment.

Downstream vacuum remains stable and at the nominal value after finding small leak with ISO and tightening bonnet bolts slightly.

Grounded NEG feedthroughs and extractor feedthroughs, replaced anode bias cable: by baking with a 10kV center pin socket around the pin, it did not move during the bake and reinserting the cable was straightforward.

Cleanup continues, we'll store all bake equipment in the tunnel for the time being until we have high voltage processed the gun and run beam to 1D successfully.

Riad and I moved mirror puck into HV chamber.
