The last physics run for Run 5b.
|
| 67202- |
July 31, 2006 |
The EMT prescale is changed back from 3 to 1.
|
| 64894- |
May 17, 2006 |
The old TSF firmware is installed back to both of the TSF-X and TSF-Y crates.
|
| 64106- |
April 22, 2006 |
The old DCT crate is again taken out of the data-taking.
|
| 64105-64885 |
April 22, 2006 |
Both of the TSF-X and TSF-Y crates with version_9 firmware in this run period.
|
| 64104 |
April 22, 2006 |
TSF-Y crate with version_9 firmware while X crate still has the user-reset-problem-fixed version.
|
| 64100-64103 |
April 22, 2006 |
The TSF-X and TSF-Y crates have the user-reset-problem-fixed version. There are TSF->ZPD transmission errors. ~5% ZPD damages, so we decided to roll back to the version we took data in January-March. The old DCT crates are back on for testing purpose.
|
| 63595- |
April 5, 2006 |
The old DCT system is not in data-taking from now on.
|
| 63527 |
April 3, 2006 |
First physics run after PEP recovered from the shutdown for Q2 chamber/bellow replacement.
|
| 63354- |
Mar.27, 2006 |
A new and improved version of the TSF firmware is installed to both of the TSF-X and TSF-Y crates. No power cycling is required anymore if timing signal was lost unexpectedly.
|
| 62240- |
Feb.14, 2006 |
DCH front-end FEX mode enabled
|
| 61369- |
Jan.16, 2006 |
Changed the EMT prescale from 1 to 3.
|
| 61147- |
Jan.10, 2006 |
Swapped the boards for TSF-X8 and X9. What seems to be a neighbour data problem between TSF X8-X9 in the new TSF system (since run 60947) disappeared after the board swapping. Run 61147 is the first good physics run after board swapping.
|
| 60996 |
Jan.6, 2006 |
about 200 TSF damaged events. See HN posted.
|
| 60947-63353 |
Jan.4, 2006 |
The first colliding physics run after the new TSF-X firmware (test_9 version) went in.
|
| 60597-60600 |
Dec.26, 2005 |
Old TSF-Y4 has trouble, see screen shots for the TSF Comparison plots and the Old TSF occupancy plots. A reconfigure solved the problem. This only happens to the old TSF, and has no impact on the data quality.
|
| 60166 |
Dec.12, 2005 |
L1T damage for TSF-X 0,1,2,3, 12, 13, 14, and 15 and also for ZPD 0, 1, 2, 5, 6, 7. A reconfigure solved the problem.
|
| 60043-60044 |
Dec.9, 2005 |
The mis-match between the new and old TSF is for TSF-X7 (or wedge number 7), and they were either no match at all or location matched only between the new and old TSF's. A dip in the BLT phi map was seen too. It turns out to be a problem with the old TSF-X7. A reconfigure solved the problem.
|
| 59743 |
Nov 29, 2005 |
First physics run with new TSF firmware (test_8 version) in TSF-Y only (TSF-X still uses the old firmware).
|
| 59565-59575 |
Nov 24, 2005 |
A dip in SL10 for both new and old TSF's. It went away after the detector was ramped down and up.
|
| 59485 |
Nov 19, 2005 |
First colliding beam run for Run 5b after DCH Phase 2 electronics installation. Note that the old DCT system has been back on since the October shutdown.
|
| 58384-58421 |
Sept 27, 2005 |
This run range is where the TSF and ZPD data got affected by the bit corruptions in TSF-Y. A DCC board was replaced after 58421. We know for sure that run 58385 is completely bad while only the last 9 minutes of run 58384 contained the damages. The rest of the runs might be okay. However, runs 58384-58399 are marked unusable due to DIRC problem.
|
| 58036-58039 |
Sept 15, 2005 |
Background runs
|
| 57991- |
Sept 13, 2005 |
The old DCT system is out of data-taking from now on.
|
| 57921 |
Sept 10, 2005 |
PHYSICS_L1PASSTHRU run with 1Z for trigger rate studies (on-resonance data).
|
| 57920 |
Sept 10, 2005 |
PHYSICS_1E_L1PASSTHRU run with 1Z replaced by 1E for single photon studies (on-resonance data).
|
| 57874-57885 |
Sept 9, 2005 |
affected by a timing shift (by 1 15MHz clock tick) in the DCH electronics. See HN posted.
|
| 57689-57690 |
Sept 2, 2005 |
Both runs are physics_L1passthru runs (off-resonance data) even though ConfigKey is 1698 for run 57689 and 169f for 57690 (due to problem with TCF leaf node).
|
| 57515 |
Aug 27, 2005 |
One physics run without the DCZ in the partition because it caused failure in configuring ORC. A power cycle of the DCZ crates solved the problem.
|
| 57211- |
Aug 16, 2005 |
Physics runs with a new version (v2.2) of GLT FC firmware. We see some EMT->GLT and DCT->GLT transmission errors, as well as a small fraction of events with GLT-FC word corruptions.
|
| 57087 |
Aug 12, 2005 |
First physics run with a testing version (v2.0) of GLT FC firmware. We see some EMT->GLT and DCT->GLT transmission errors, as well as a small fraction of events with GLT-FC word corruptions. The original firmware was back in place after this run.
|
| 56968-56969 |
Aug 10, 2005 |
EMC has 24 (mistakenly marked) dead channels.
|
| 56797 |
Aug 3, 2005 |
First run after the bug in the DCH feature extraction code was fixed .
|
| 56074-56078 |
July 12, 2005 |
HER single beam data taken for background rate study. Note that all these runs have DCZ in the configuration, except run 56074.
|
| 55680-55682 |
June-29 2005 |
TSF damages showed up and then disappeared after reconfigured. The problem seemed to happen to TSF-X15. The new TSF-X ROM logfile indicated that there were out-of-frame errors. See HN posted here.
|
| 55386 |
June-17 2005 |
The parasitic (old) TSF-X15 has dips in the occupancy plots. See HN posted here. This doesn't affect new TSF, and it's still a good run.
|
| 55381 |
June-17 2005 |
TSF damages showed up and lasted about 10 minutes and then went away on its own even without reconfigure. The problem seemed to happen to TSF-X15. The new TSF-X ROM logfile indicated that there were out-of-frame errors from 1:35-1:46am.
See HN posted here.
|
| 55259-55266 |
June-13 2005 |
L1 rate was about 20kHz and deadtime > 70%. GLT output lines dropped due to configuration problem with createFileTable. Bad runs!
|
| 54999-55000 |
June-5 2005 |
The parasitic (old) TSF-X15 has dips in the occupancy plots. See the new vs old TSF comparision plots. The problem went away after a reconfigure. The new TSFs are okay, so it doesn't affect data quality. No impact on real physics trigger! These are still good runs.
|
| 54988 |
June-4 2005 |
The parasitic (old) TSF-X14 has dips in the occupancy plots. See the new vs old TSF comparision plots. The plots here showed that the new TSF system was in fact okay. The problem went away after a reconfigure. The new TSFs are okay, so it doesn't affect data quality. No impact on real physics trigger! This is still a good run.
|
| 54709 |
May-25 2005 |
The TSF-X0 in both new and old TSFs showed a big gap in the occupancy plots. This is due to fibers damaged by a gogher. Bad run!
|
| 54217-54224 |
May-5 2005 |
L1 rate went crazy to 5 kHz, caused by corrupted TC and the GLT objects that were used in the GLT line cuts were all shifted up by one. See the associated TrigOper and DetOper HN postings. Data in this run range are NOT usable.
|
| 53460 |
Mar-28 2005 |
The DCZ configuration is now all from the database, including TSF 6 bit LUT, BLT mask, all DCT DAQ latency, and ZPD LUT. The ZPD configuration test was the last one put in and tested on March 28, 2005.

Jul-30 2004 |
Eunil : We had dips/spikes on TSF SL5,6,7 around 4:00 am. It looks like
the entire TSF-Y3 board was in trouble. Re-configure solved the
trouble as usual.
hn associate with is available
and see
this
for plots.
|
| 50254 |
Jul-19 2004 |
Eunil : TSY SL7 cell distribution showed
dips and spikes.
Entire Y7 board seemed to be affected. Reconfigure solved the trouble.
|
| 50247 |
Jul-19 2004 |
Eunil : DCT generated 100% deadtime. TSFY rom log showed out of frame error
all the time. Went to IR2, and confirmed that TSFY0 SYNC* LED was on. As
reconfigure by pilot did not solve the trouble, power recycled the TSFY
crate and the trouble went away.
|
| 49759 - 49776 |
Jul-04 2004 |
Eunil: A single dip in TSF SL1. This is my first time to see this single
dip from TSF cell distributions.
See the
hn posting.
The cause of this is unknown but mysteriously disappeard.

Eunil: EMT fan tray died. Ray Rodriguez came in and replaced it with
the one in the teststand (central lab). The cause of this is unknown.
|
| 49287 |
Jun-19 2004 |
Eunil : DCT caused 100 % deadtime. The TSFY rom log showed
19-Jun-2004 22:24:14 odf-dct-3-> L1DTsfFexEngine::L1Accept(): Out of frame for
1 time(s) with damage 0x0
for 20 minutes. Reconfiguration solved this trouble. According to the log,
1) rebooting of the rom (due to dch TDC reset storm), 2) odf-dct-3 Out
of frame, and 3) reconfiguration happened consecutively.
See
hn
for more details.

Eunil : TSFY-26 board on Y5 slot (ID:20002205) now formally has the tag
describing the RUN/LOAD LED is broken.
See
hn
and all threads associated with.
|
| 48814 |
Jun-04 2004 |
Eunil : GLT-FCT word corruption histogram fired in the bin 18. Also
FCTS epics showed a flat rate of ~300 Hz on lines of 17-23. Two
troubles believed to be independent. This appeard on one cosmic run.
The source of the latter is unknown but there is much better understanding
on the former. See
hn
and all threads associated with.

Jun-02 2004 |
Eunil : Got paged due to
same problem as happened on May-24 (See below). Y-7 data were corrupted.
Reconfigure solved the trouble.
|
| 48680-98 |
May-31 2004 |
Eunil : Got paged due to a
dip
in SL1 x5. Dip appeared to be in a group of
last 4 cells in x5. This time, multiple reconfigurations did not solve the
problem. We added dcz in x5 and saw the
dip
in the new tsf as well, indicating
the trouble is not from the trigger but likely from the DCH.
In parallel, we power-recycled the DCT tsf crate but did not work. We also
swapped x5 and x4 boards. Unfortunately after x5 and x4 were swapped, the
dip went away.
Now in x5 slot, we have TSFX18 (20002192) and in x4 slot, we have
TSFX15 (20002199).

May-28 2004 |
Eunil : Got paged due to a problem with JAS HTML configuration for DCT/BLT/GLT
monitoring histogram. The cause was the incompatibility between new L1TFMon
histograms directory structure and JAS XML expectcation.
Gregory fixed the problem immediately.
|
| 48423-8 |
May-24 2004 |
Eunil : Got paged due to spikes in
distributions for TSF SL5,6,7 and PTD SL7.
Plots can be found for
48428. Page 4 and 5 contain TSF and PTD distributions.
It looked like Y-7 data got completely corrupted. Again, reconfiguration
removed the trouble.
|
| 48129 |
May-14 2004 |
Eunil : Got paged due to _slightly_
unusual
distribution for TSF SL2 and SL4. E-log (day shift) has two histograms
attached. It disappeared as run continued and I don't think it is a real
trouble but post here for the record.
Plots can be found for
SL2 and
SL4 respectively.
Later (19/May) Su Dong noticed other oddities in PTD and TSF SL9,10. See
the
hn.

| 48037,35 |
May-11 2004 |
Eunil : Got paged due to 1) no L3 tracks in event display and 2) empty FastMon plots
for entire TSF/PTD/BLT/GLT. 1) had to do with a new L3 build installed earlier afternoon
and 2) had to do with the update in FastMon GUI. Both problems went away when we
backed out to old versions. Data quality should be ok for both cases.
Details can be found in the hn (
816 ,
817)
and associated threads.

May-09 2004 |
Eunil : There was a TSF board failing configuration. It was Jamie
who got paged, as Eunil was out of town. It appeared that the board
died for good. Details can be found in the
hn and associated threads.
|
| 47719-21 |
May-02 2004 |
Eunil : Got paged due to dips and spikes in TSF SL 5,6,7 and PTD A7 cell
distributions. Location of dips and spikes corresponded to the
entire TSFY1 board.
An immediate reconfiguration was asked to the pilot and the problem
disappeard afterward.
Details can be found in the
hn and associated threads.

Apr-20 2004 |
Eunil : Installed 10.18.0 version of libL1DctApp.o (1: cp libL1DctApp.o
from $BFDIST/online_releases/10.18.0/lib/segment/vxworks/, to dataflow/dct
2: make a soft link to libL1DctApp.o 3: edit productionStartup/startup and
add dctsegtest 14) A DAQTEST run went allright.
|
| 47257-60 |
Apr-16 2004 |
Eunil : Got paged due to high deadtime for the BACKGROUND runs. L3 rate was
high but unable to find the cause. What should have been done is to take a
look at L3 OEP trigger lines and identify the line(s) causing the high rate.
(In ir2, "Level 3 Trigger Output lines rates" window) It turned out that
for this time L3InputPulser(=sourcecalpulser)/L3OutPulser(prescale=1) was the
line caused the high deadtime.
|
| 46995-9 |
Apr-08 2004 |
Eunil and Jamie: Tested online release 10.17.0 with cosmic runs and backed
out 10.12.0.
Details can be found in the
hn.
Later noticed BaBar kept running 10.17.0 and worried incompatibility between
dct loadable and rest of the online env but turned out to be ok.
|
| 46927 |
Apr-06 2004 |
Eunil and Jamie: Tried to run with PHYSICS_L1PASSTHRU_REDUCED but
gave us more than 50 % deadtime so we stopped. Lost 1 minuite.
Rainer informed us that the configuration was not quite ready.
|
| 46544 |
Mar-26 2004 |
Eunil: FastMon showed a dip in TSF SL5 cell distribution. Looks like
the are cells
45-48, corresponding the first four cells in TSFY2. Appears to be an
Elephant chip fault. Dip disappeared after the reconfigure. Runs
46544-46546 appear to have this dip. See here for a hn posting.
