===================================================================
EVENTS
00:00 Shift has started smoothly. We are taking production data
on 3He target. Target polarization at the moment is 63.1%
The runs that are currently running are 3029/21907.
There is still a problem with the HRS-R Q1 magnet. The
alarm sign still turns on from time to time.
00:24 Started new HAPPEX Run #31454.
00:30 Half wave plate was inserted (now it is IN) between
runs #3030(OUT) and #3031(IN).
01:00 I have stated new Compton run #17112. Before I was able
to do that I had to reset Coda, because previous run did
not end properly. Coda is now running but Compton is not
working. There is no heart beat etc. Alexandre knows about
this problem and he told me, that he needs to reboot few
things (when there will be some time with no beam) before
Compton could work again.
01:51 I noticed that HAPPEX is not working and that LUMI
histograms are empty. This has happened during run
#3033/#21911. Need to wait until these two runs end before
we can try to fix it.
02:20 Made NMR frequency sweep. New polarization is 61.98%
02:21 After run #3033 ended I tried to end HAPPEX run #31454,
but Coda reported that run did not end properly. I had
reset Coda,configured it again and started new run (#31455).
It did not help. Coda was still not counting. After that I
checked ROCs.They all seem to be responding. In spite of
that I rebooted ROC 26. Then I reset coda, configured it and
started new run (#31456). Still nothing. After that I rebooted
ROCs 26, 23 and also TS1 and started Coda again (#31457).
Because this also did not help I decided to close all the
windows and start everything from scratch. I followed the
instructions on Wiki. When Coda was up again and all ROCs
connected through telnet, I rebooted all ROCs(23,26,28)
and TS1 again. After successful reboot I configured coda again
and started new run #31458. Now Happex seems to be working.
03:14 When I came to start new Compton run I relaized that Coda
counted only 5 events. Since we know that Compton is not
woking I decided just to start a new run. When I tried to
end previous run it did not nd properly. I had to reset
coda, reconfigure it and start a new run. At that point I
got warning messages:
EB0,1,2,5,6 did not reported status for xx seconds.
and after a few secconds a error message appeared:
Prestart failed!
I killed coda and used "coda reboot" command. After
the successful reboot I started a new run #17114. Now coda
seems to be counting, but there is still no heart beat.
04:50 Right after the start of runs #3039 and #21917 the left Coda
stopped counting and Datamon was showing 100% dead time.
We stopped both runs. Left arm coda reported "End-of-run
failed!". We killed left coda and restarted it. After
successful restart and configuration of coda, we started new
runs. It seems to be working again.
Runs #3039 and #21917 are JUNK!
05:08 New Compton Run #17115
06:52 Started new Happex run #31459. We also did the NMR frequency
sweep. New polarization is 62.9%
07:32 New Compton Run #17116
