Gun chamber pumping down
Next steps: Move equipment for mini-bake of prep chamber tee, then start moving all equipment for the bake of the gun. This will involve intermittent crane work in the ISB

Pump cart has pumped down to 2e-6 Torr. Tried ion pump briefly, pressure in gun too high to start IP.

The pump cart RGA is warming up, ion pump on cart is on, isolated from chamber and pumping on RGA only.

I'll check periodically this weekend to verify that pressures continue to drop. There is a huge surface area in the system due to the NEG pumps, so it is always slow to pump down.

I rolled the suitcase near the door of 1137 and retrieved some bake parts that had been loaned to another group.

Facilities is working on a glycol leak issue and the repair work has effected the LINAC service building cooling.
The cryogenics CAMAC crates in the South LINAC service buildings are overheating.
We have coordinated with F&O and they recommend we open the roll up doors and allow additional cooling to prevent damage.

Installed a spare receiver card in place of the broken card in the BSY slot. The previous faults are cleared now.
I noticed that it looks like both the BSY receiver card and the Hall D receiver card are asserting the same address, so Joe and I are going to look into that next.

The alignment of the electrode went well, with it able to be adjusted to minimal offset (survey transmittal to follow). Began evacuation of chamber, and second survey conducted when chamber pressure was under 1 Torr.

Plans for today:
- Continue evacuation, set up for HV chamber leak check Monday.
- move suitecase and another pump cart to the tunnel: we need to attach, bake the tee, and move pucks around before starting the gun bake.
- Gather bake equipment and start moving to tunnel.
