COMMENT ON Swap BSY and Hall C BLA receiver cards
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.

-Did another clean up of the work area now that all the new equipment is in place. Began pulling outgoing control wires and gathering materials for the new high voltage and control wiring.
-Verified turn-to-turn ratios are still correct on all three phases of the transformer after installation.

gun electrode: surveyed and under vacuum
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.
