Finished containing the spliced cable from the 4 channels in NL01B01 to Rack NL01B11. Cables have been labeled and stored in the cable trench. Cables have been terminated with the proper ends for the 12A LNS. We still need to install the Chassis and connect the chassis to power and the network.

Looked at supplies with Leo. VIP1I06 supply is behaving poorly - very noisy. The others are sitting at their baseline with some bit noise for pressure, while the current flickers around a bit more.
Things look fine other than the one supply that seems to be a lemon.

Turned off VIP0I04A (chopper 2) ion pump Wednesday. The blips since beam has been off are small and infrequent. Turning off VIP0I04A doesn't seem to have changed anything.

I'll turn off VIP0I03 (chopper 1) for the weekend with VIP0I04A back on and see how that reacts.
