15:30 Herman from new shift arrives, finds a lot of activity.
16:00 Nick arrives half hour late due to Cascade muon decay PRL
meeting with Godfathers, Herman says the activity is
16:20 HV for CsI channel changed from 1112 to 1327 V for crystal
number 1691 by Jason Hamm.
16:40 Visual inspection of hall and helium bags completed
Crash buttons on the analysis magnet are left engaged
until Search & Secure request:(D. Northacker, Herman, Patricia)
17:30 D. Northacker is repairing the air duct to the Etot power supply
rack on the west side column plenum. This repair amounts to
replacing inefficient air duct material, requiring under floor
