TITLE: 01/14 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Another busy day of upgrades; JAC installation and HAM7 beam alignment continued while the move/upgrade of BS DACs began today and should wrap up tomorrow morning. Jim also discovered a failed power supply at EX which looks to be the reason the chamber can't be recovered, so he and Marc are starting to take action there.
