Data shift report (08-May-2000 to 12-May-2000)

From run 19512 to 19527
-------------------------------------------------------------------------
First full week with WFDs out of acquisition.
The WFDs have physically been dismantled from SM1, SM2, SM5 and SM6
In a first moment the run length had been adjusted to ~10-10.5 hrs (starting
from run 19502) but this caused some problems with Pisa MV6 that produced
the RUN-END ~30 min. before the real run closing. So, starting from run 19515,
the run length has been set to 130000 Kb, i.e. ~8.8 hrs.
In the following tabel I reported the run duration and the uVax's dead time
before and after the WFDs decommissioning:
Run duration dead time (uVax1/uVax2/uVax3)
with WFDs ~ 5.4 hrs ~ 1.6% 2.0 1.7
w/o WFDs (runs19502-19514) ~ 10 hrs ~ 0.6% 0.8 0.7
w/o WFDs (final run size) ~ 8.8 hrs ~ 0.6 0.7 0.6
During this week a big effort has been done in the last WFDs calibrations.
PULSER/WFD, FMT/WFD, LASER/WFD, LAMOSSKA and SMT calibrations have been
completed foR all uVaxes. Sophia wants to repeat SMT calibrations on uVax2.
We'll perform them the next Wednesday.
Following problems happened this week:
- run 19513 crashed on Monday morning (@ 9:35AM) for a broken PHRASE
fan unit on SM4 (crate 1). Yiannis fixed it replacing one ball bearing;
- starting from run 19510 channel 6TH0 (6T09-6T16/side-0) was dead on both
CISPAM/HIPT (also during last LAMOSSKA calibration on uVax3). No signals
from the corresponding three fan-in/fan-out (CSPAM/HIPT/LAMO) outputs
were present. Problem fixed swapping this channels with a spare one;
- starting from run 19515 we received a lot of NO Q's responses (~5000)
from SM2 Stop Master (no XStop signals between SM1 STPM and SM2 STPM).
Problem fixed re-soldering the disconnected wire on the relative input
channel;
- during run 19527 there were a lot of no Q's responses from the InterERP
TDC on uVax3. Problem fixed unplugging and plugging back the Ehigh3 input
on the InterERP Timing Manager Module;
- run 19527 stalled because uVax2 was not collecting data. Everything
solved by rebooting the uVax;
- starting from Monday there was a synchronization failure on the PHRASE
4M03-4 MIXER module. Problem fixed swapping one fan-out output with a
spare one.
On Thursday afternoon the temperature on the Attico went up till 27.4 C. This
was due to an interruption of refrigerating system (for 1.8 hrs) and caused
2 fan units breaking...Again in the night there was a similar warmup due to
a (water) pump failure. Fortunatly it didn't caused any other damages on
MACRO.
The following TOHM channels have been disconnected (based on Erik's 3-sigma
hottest criteria):
uVax1 --> 1T03-0, 1T11-0, 2C14-0, 2T16-1
uVax2 --> 3T07-1, 3T12-0, 3T13-0, 3T17-0,
4W05-1, 4T02-1, 4T10-0, 4T11-1
uVax3 --> 5T03-1, 5T05-1, 5T06-0, 6B13-0,
6T11-0
Other TOHM channels disconnected in the past are: 3T06-0, 3T06-1, 4T12-1,
5T01-0, 5T01-1, 5T02-0, 5T02-1, 5T17-1, 5W08-0, 5W08-1, 5W09-0, 5W09-1,
5W14-0 and 6T02-0.
TRIGGER RATES:
TOHM --> 4T13 ~5mHz, 5B13 ~4mHz, 5B12 ~3mHz
ERP --> 3B07 ~5.5mHz
LIP --> 1B16 ~0.3mHz(!), 1B12~0.9mHz, 1B14~0.7mHz, 2E10 ~4.5mHz,
3E04 ~6mHz, 5T02 ~0.5mHz(!), 6T12 ~9mHz
ERP-GC --> 1E01 ~125mHz, 6W12 ~90mHz, 6S04 ~120mHz, 6S07 ~70mHz.
PHRASE --> 1E09 ~35mHz, 2W14 ~34mHz, 5W11 ~90mHz
LAMOSSKA:
There are still not justified LAMOSSKA triggers for SM5 (LAM5-0).
CSPAM/ERP efficiency:
With the new run duration we have more statistic. The 'problematic'
boxes are 3B07 ~40%, 4E14 ~60%.
ERP/LIP efficiency:
Low efficiency for 1B12, 1B14, 1B16,1T15, 1C08, 1C14, 1C15, 5T02, 6C09
and 6C10.
SPU: still hits on ERPI, ERPII, SPARE and LED on uVax1 (sometime 1/2 VETO
bits too).
STOP MASTER:
The fake hits on SM4 CIT disappeared after disconnecting 4T11 from TOHM.
CALMOD:
2 weeks analysed for ERP constants: ref. runs 19460 and 19497.
They cover runs untill 10-MAY-2000
DATA RE-PROCESSING:
Last DD processed is DD282. The DDM processing started in order to
produce new CALMOD constants for all MACRO runs with ATTICO in
acquisition.
