Overview of shift:

Smooth datataking with good beam quality and stable intensity at 9e12
until 17:50, then very intermittent data due to banana and CsI readout probs.
until 21:26. Smooth datataking after that.
Description of Shift:

run spill time comment
14966 15:30 Inherit smooth running datataking from dayshift

161 16:08 Run ends, change tapes

14967 1 16:11 Begin new run

45 17:20 Kfrend to try to fix out of time latch for vv'.
VV' latch for previous spills in this run screwed up.

67 17:50 Banana ch2y-7 busy enable. Paged Jason after
multiple resets failed. He's in working on it.

CsI 2012 readout occupancy too high, and has
been since run 14965.

172 20:10 CsI stream readout problem. End run 14967.
On run initialization, pipeline crate01 did not
init properly and damp_open lost server communication.
Again pipeline crate01 did not init properly.
Hard reboot of crate01 fixes problem.

14970 1 20:35 Start run. Banana ch 2x-2 hangs trigger
Jason still working on banana problem.

21:26 Jason does minor surgery on banana card and it
appears to be working for now. From spill 38 on is
fine. Previous spills have a hyperefficient STT
because the 2x STT cables were not plugged in until
spill 38.

The banana problem doesn't affect the data; it justs
hangs the trigger.

CsI 2012 readout occupancy problem fixed by
earlier pipeline init.

153 23:59 Banana problem again, hand off to owls
