Data shift report (24-Jul-2000 to 28-Jul-2000)
-------------------------------------------------------------------------
by Nicola Zaccheo
From run 19758 to 19774
-------------------------------------------------------------------------
The acquisition was quite regular during this week.
The gas system has not been debugged and it often is off.
During this week we received 1 data rate warnings (run 19770). Checking
the MACRO long timescale data rate, we are quite sure that there are no
problems for the detector but we have only to change the expected range of
typical MACRO run data rates (now that the WFDs are no longer in acq.) where
the reference data rate (defined run per run by DEAMON) should fall (Erik
was working on this).
A couple of no Q responses per run from M:2,B:2,C:5,N:21. One no Q sometime
from M:2,B:2,C:6,N:21, M:3,B:2,C:5,N:21, M:3,B:2,C:6,N:21 AND M:1,B:2,C:5,N:21
During runs 19758 and 19769-19770 the CSPAM 4EL-1 channel gave no triggers
(was dead). Checking the electronics, I found the corresponding RG58 cable
connector (plugged in one of the PHILLIPS Disc./Lach. input) unscrewed.
I fixed it and this channel is now working.
We received the following PHRASE L/R warnings:
5W11 L/R = 0.8 run 19759
= 0.76 run 19760
= 0.8 run 19761
= 0.67 run 19763
6W06 L/R = 1.2 run 19764
= 1.26 run 19769
TRIGGER RATES:
TOHM --> 4T13 ~8mHz, 5B13 ~4.5mHz (1T13 @ 9mHz during run 19767
usually @ 0.5mHz during)
ERP --> 3B07 ~4.9mHz
LIP --> 1B12 ~1mHz, 1B14 ~0.8mHz, 1B16 ~0.3mHz(!), 1C08 ~1mHz,
1C15 ~1.1mHz, 2E10 ~9.5mHz, 3E04 ~6.5mHz, 3W13 ~0.6mHz,
4B01 ~1mHz, 4B02 ~1mHz, 5T02 ~0.7mHz, 6C09 ~1mHz,
6T12 ~11mHz
ERP-GC --> 6W12 ~90mHz, 6S01 ~62mHz, 6S04 ~105mHz, 6S07 ~95mHz.
PHRASE --> 5B04 ~27mHz, 5W11 ~35mHz (5W04 @ 55mHz during run 19767)
FMT:
No problems reported
LAMOSSKA:
There are still not justified LAMOSSKA triggers for LAM50. Sometimes
also for LAM51, LAM60 and LAM61.
CSPAM/ERP efficiency:
The boxes with systematic inefficiency: 2B04 ( ~80%), 3B07 (~43%),
3B10(~79%), 3B12(~80%), 3B14(~70%), 3E07(~70%), 6T07(~75%).
ERP/LIP efficiency:
Low efficiency for 1B12, 1B14, 1B16, 1C08, 1C15, 1T10, 1T12, 1T14
1T16, 2B07, 5T02, 6B08, 6B09, 6B11, 6B12, 6C09, 6C10 and 6T09.
SPU: still hits on ERPI, ERPII, SPARE, LAS and LED on uVax1 (sometime 1/2
VETO bits too).
STOP MASTER:
No problems reported.
PMTs CHECK:
Checked the PMTs signals on SM5. These are the differences that I found
respect last time:
5B04-1 gain @ -4.2mV/spe
5B05-0 gain @ -3.6mV/spe
5B05-1 a bit filled in spe
5B09-1 noisy fan-out
5B11-1 broad spe
5B12-1 gain is O.K. for me (last R.G. measurement -4.5 mV)
5B14-1 a bit bright
5C01-0 broad spe
5C02-0 very bright, unstable, gain @ -3.4mV/spe
5C05-0 gain @ -3.7mV/spe
5C05-1 gain @ -3.6mV/spe
5C06-1 broad spe
5C08-1 still broad
5C09-0 gain @ -3.7mV/spe
5C09-1 noisy fan-out
5C13-0 gain @ -3.2mV/spe
5W04-0 a bit bright and broad spe
5W07-0 filled is spe
5T01-0 still a bit bright and filled in spe, gain @ -3.5mv/spe
5T05-0 gain @ -3.6mV/spe
5E05-1 gain @ -3.8mV/spe
I'll update the web page ASAP
CALMOD:
1 weeks (LED/TDC and muon) analysed for ERP constants, ref. run 19753
It covers the period till Wednesday, 26-Jul-2000
Various:
Problems with AXCMAC1 runs and LGB-files copy.
Manually launched the MAKEDST job for run 19692 (crashed because of
no LGB file was copied).
VAXGS shut-down last Monday. I re-launched all the MACROUSA jobs.
Roberto swapped a fan out PHRASE channels (6T07-6T08) with a spare one.
Piller maintenance on Wednesday..MACRO ran on the unprotected electrical
power line for a couple of hours. One LeCroy HV alarm generated during
the switching.
Oil leak check performed by Roberto on the west side of SMs 4,5,6
and South face.
The reports of the realtime/reprocessing RARE/GC DSTs check and the
already recovered files have been moved on
DISKMACROSCRA3:[MACROUSA0.BACKUP.MISSING-**] (** = GC or RD)
Today I found the VXMACB disk_mon job still executing (since yesteday)
I stopped and relaunched it.
