During the access I was able to track down a couple of wire map problems. I made minor cabling changes and resolved two noisy channels. I plan to create final versions of the cable maps and post them on the electronics rack and also on the web page.
I lowered the threshold on chamber 2 to 2.35 V in order to allow lower HV as requested by Bogdan. The system remained stable.
Albert and I mounted a one inch sheet of plastic material covering the window between the target's magnet box and the opening of the BigBite magnet also as requested by Bogdan.
I looked at some cosmics data and all channels seem to be operating as expected. Chamber 3 has 4 silent channels near the edges, which were not resolved during the installation period, but everything else seems fine.
