Data shift report (31-Jul-2000 to 04-Aug-2000)
-------------------------------------------------------------------------
by Nicola Zaccheo
From run 19780 to 19794
-------------------------------------------------------------------------
No particular problems for the acquisition during this week (except Friday
afternoon).
Durin run 19782 the HIPT channel 5TL1 was dead and had 1mHz only of HIPT
trigger rate during run 19783.. This channel had a very low HIPT trigger
rate starting from run 19779 (~1.7mHz).
I debugged it during run 19784..I found a similar problem that afflicted
the CSPAM 4EL-1 channel last week-end (an unscrewed connector). It is now
working fine.
The gas system has still problems, but went off with lower frequency.
A couple of no Q responses per run from M:2,B:2,C:5,N:21.
On Friday 4th of August at 2:45PM there was a black-out in the gallery lasted
3hrs..Roberto and I were working at SM4 Laser (under the detector)....
We shut-down MACRO and the computers (VXMACA/B) before to be evacuated because
the emergency lights didn't work..When the power came back we decided to
go in the tunnel and restart the apparatus...(I had to leave for my vacations
at 5:00PM, so I decided to postponed my departure at the next day)..
We left the underground laboratories at 9:30PM while MACRO was running w/o
uVax1 (problems in a fast STAS chain on SM1) and w/o uVax5 (broken PHRASE
module)..
TRIGGER RATES:
TOHM --> 4T13 ~8mHz, 5B13 ~5mHz
ERP --> 3B07 ~5.5mHz
LIP --> 1B12 ~1mHz, 1B14 ~0.6mHz, 1B16 ~0.3mHz(!), 1C08 ~1mHz,
1C15 ~1.1mHz, 2E10 ~11mHz, 3E04 ~6.5mHz, 5T02 ~0.6mHz,
6E12 ~11mHz
ERP-GC --> 6W12 ~90mHz, 6S04 ~90mHz, 6S07 ~90mHz.
PHRASE --> 5B04 ~28mHz, 5W11 ~25mHz
FMT:
No problems reported
LAMOSSKA:
There are still not justified LAMOSSKA triggers for LAM50. Sometimes
also for LAM60.
CSPAM/ERP efficiency:
The boxes with systematic inefficiency: 3B07 (~48%), 3E07(~78%),
4E01 (~77%) and 6T07(~78%).
ERP/LIP efficiency:
Low efficiency for 1B12, 1B14, 1B16, 1C08, 1C15, 1T10, 1T12, 1T14
1T16, 2B07, 5T02, 6B07, 6B09, 6B10, 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 SM6 - no new problems found.
CALMOD:
1 weeks (muon data only) analysed for ERP constants, ref. run 19772
It covers the period till Wednesday, 02-Aug-2000
Various:
Problems with the AXCMAC1 copy "DENTRO-FUORI" stopped because the
DOLIST job was not running on VXMACA. I restarted everything and
I also manually copied on AXMAC1 all missing LGB files.
The MACRO inventory is completed (included the major commercial
laboratory devices). You can find a new link in the hardware info.
area on the MACRO On-Line web page.
I selected the following PMTs to ship to the Saclay institutions:
serial nr. tested by: comment
8624 17NOV00 MO He-inside
8968 12NOV00 MO He-inside
8567 JAN97 SS He-inside
They have already been transported to the 'magazzino' that should
take care of their shipping.
