------------------------------------------------------------ Date: Sat Mar 1 08:09:58 2003, Shift: 00:00-08:00 Supervisor: BHS, with: Log book#14 pages 41 - 41 Shift Summary: ------------------------------------------------------------ We've had one long store this shift, lasting from 01:00 to 07:30. The first hour was spent steering, then we had quite high BG for another hour, but after that conditions were fine. BUT: I have had several problems which are now resolved, but unfortunately took most the night to figure out. When I wanted to start a run, a few things broke: * fb3 didn't respond - this was fixed via Steves wonerfull web presentation * after this, I couldn't contact fb4. I tried resetting the slow controls, and this apparently did the trick. * but then the real problem showed: I have had no data from TOFW/TOFWII. When I turn on fb4 in the daq I get a whole slew of error mesages (see e-log for screenshot) about unpacking problems from TOFW(II) and sometimes ZDC. Going out to the FEH, I found that the TOFW CAMACs seem dead or in a strange state - CA6 shows "No-Q" and "NO-X", while CA5 has no lighs on at all. All the other CAMACs show "BUSY"... * in the end, the solution (thanks to Flemming) tured out to be resetting the cards SB5 and SB6 in the VME crate in rack 7 individualy. I took some FS data (runs 8147 and 8150) while this was going on, but since the INEL counter TDCs were also dead these data are unfortunately useless :-( Lesson from this: The INELs should be added to the supermon autoprinting, because as it is now the INEL tab is outside of the supermon window and easily forgotten. (As I did tonight - had I seen that I'd have gotten someone out of bed...) Currently the beam has been dumped and everyting appears ready for the next store. ------------------------------------------------------------
