Some progress today at UITF, day#2 of run0:

1) we have formal beam authorization for MeV beam delivery to waist height dumps
2) Opened all the valves along the waist height beamline, decent vacuum, but the booster still pumps on the beamline, which I guess is no surprise.  Pressure at downstream ion pump doubles from 5 to 10 nA when all beamline valves are opened
3) viewers are working, still figuring out how to test the HDIce dump viewers, Gary hooking up compressed air, Chris Norris installed the anticollision circuit, Scott working on software mods
4) Clyde is making new epics screen for the buncher
5) Manny fixed the heater cable problem, we can add heat to the booster.  He added the interlock chassis
6) Scott figured out how to implement the circuit for QE scans
7) Kevin is wiring up Rowgowski Coil #2 to the lockin amp rack

Plan for tomorrow:
1) Scott, can you help Kevin with bnc cables:  make cables from RC#2 to lock in amps, and 10 MHz reference signal - probably best to cut the cable near the rack, add male connectors to each end, then the cable can be used to provide reference at two locations for the rack
2) figure out who will help energize the booster, call it ready for handoff to me/Yan/Joe and Reza
3) test the HDIce dump viewers?
4) get the ion pumps ON on the elevated beamline?
5) lock up at 10am for HCO with beam, at 200 keV
6) RF group continue buncher and booster work, while we make keV beam
