16.00 - 24.00 Summary
note: this summary has been reconstructed from
the memories of those on shift for the first two
hours (see below)
16.00 - 16.35 Moeller measurement
16.35 - 16.45 Compton diagnostics
16.45 - 16.50 FPP chamber 3 trip
1333.....16.50-17.15.....0.4M.....no endrun event
17.15 - 18.10 Bad stuff happened. First, ROC14
died. We went to the tmpwrkDisplay.adl screen and
toggled crate resets, but the screen we got was a new
one with no correspondence to the written instructions
as to how to restart it. Jack returned the screen to its
old configuration so the instructions once again apply.
Then we tried a series of kcodas/reboots/runcontrols,
but the system would not engage. It always hung at
the et point. Anyway, Bob worked thru it all from home.
Turned out that whenever the et system started, it core
dumped. Bob was required to reboot adaqs2 to fix this,
which clobbered both the Time Account Entry Table
and the Shift Summary halog.
18.10 MCC took beam for some tweaking
half-wavelength plate removed
1339.....22.08-23.10.....0.9M.....ended run early
23.10 MCC called. Hardware problems in the south linac.
Turned out to be a door which blew open and took out the
23.20 Ended 1340 early when the ROCs stopped responding.
Problem very similar to earlier this evening. Reboots,
kcodas, etc. ROC2 and ROC3 in particular are very, very
