16:10 Around 15K events
the current in Crate-3 (U6,U7) is increased to 11.2/9.8 normal(10.0/8.6)
and also dead time increased to 96% and also data volume(1500 KB/sec)
So, the Crate is switched off
the deadtime came to 54% and data volume 300KB/sec
HV of SM 22 and 23 reduced to 1350 V
Run 5028058 started
LV crate-3 off Crate-1 & crate-4 on

Run# 5028064 PMD with all detectors HV and LV conditions earlier
17:50 HV and LV conditions as earlier. Runs may not be useful as some
tests are going on. SM 22,23 HV upto 1400 V
LV current in Crate is
0.1,0.1,13.5,13.7,4.8,9.2,10.7,9.3
Very high
on increasing the HV of SM 22 &23 This is bad
lowering down to HV again to 1350 V
After switching off crates and back on again, the current
values became normal (10.7,12.6)
So it is confirmed that SM 22,23 have problems.
It is advised NOT to raise the volatge of these SMs
Runs 5028070-74 may not be useful

we will take pedestals with Crate-1 failure and take run
if it helps to improve dead time.

Turn off and on LVPS.
Pedestal taken again. This looks better. But compared to Run 5038005:
we find
that: channel 40 doesn't come, channel 34 has a spike, channels 19
and 21
don't come now. What's going on?
1:15PM : There is no beam since 10:30AM. All the SMs are in Standby

LVPS current checked. Chain 40 and one of the(18,19,21) may be OFF.
1:35PM: PEDESTAL Run# 5038042 taken for PMD @1000V.
Chain# 40,18,21 doesn't come. Chain-34 has a spike(probably one
board has gone bad) Other chains look OK.
2:35PM : Beam comes(PHYSICS RUNNING). We are not putting PMD into run
when
beam is at high rate. Because PMD shows large error.
3:30PM : Only about ~2000 events has been taken without PMD. There was
some
problem with DAQ. After few minutes Beam breaks instantly.
6:00PM : Beam is back, we will put PMD in when ZDC coincidence rate
will comes
down (~less than 3600). We will not take 'ProductionHigh' trigger events.
PMD is ramping upto operating voltage.
6:45PM : SM(1,2,3,4,7,10,11) of CPV are at 1400V
SM(13 to 23) are @ 1400V and SM24 @ 1000V
CRATE 3,4,5 are ON.
7:00PM : Run #: 5038067 ~ 20K events has been taken for PMD with other
detectors(excluding FTPC).
PMD slows down the rate from (50-60)Hz to (25-30)Hz
From the next run took out PMD from the run.
From the online 2-D as well as ADC plot look chain 39,40 are OFF and
chain-41 gives some junk value.

2:00PM : There was no beam since morning(4:30am). There was some problem
in
AGS. Beam came around 2.00PM. PMD ramping upto PHYSICS voltage.
SM(1,2,3,4,7,10,11) of CPV are at 1400V
SM(13 to 23) are @ 1400V and SM24 @ 1000V

Now ZDC coincidence is high, we will put PMD in run when the 'productionMid'
trigger will be applied.
3:00PM : PMD is in the run.
Run # : 5039037 ---- ~73K events has been taken.
Online Plots checked: Chain-2,3,4,5,6,9 of CPV are OK.
Chain- 25,27,29,30,31,32,33,35,36,37,38,41to 46 are OK.
In some chains there is small peaks at 300 and in some chains there
is a
saturation.
'productionLow' trigger applied
3:30PM: Run # : 5039038 ---- ~ 48K events
Run # : 5039039 ---- ~ 30K events
Run # : 5039040 ---- ~ 40K events
Run # : 5039048 ---- ~ 69K events(PMD gives error>5%)
PMD is out of run. Because PMD gives 98.9% errors
6:45PM : PEDESTAL taken Run # : 5039059 @1000V and NO beam
Many chains in Preshower plane are not comming. We will take it again.
8PM: We took another pedestal. We noticed that all the channels with
VME Crate 2 didn't appear. We could have rebooted DAQ. Instead we
powercycled pmd01, pmd02 and pmdrps2.
New PEDESTAl looks fine => RUN no. 5039069.

11:00AM : There was no beam in last night. Beam came at 10:45AM.
Ramping upto PHYSICS voltage.
12:00PM : Run # :5040027 ~ 29,600 evts.
PMD is giving some JUNK in 3-4 chains. So we took out from the run,
Ramp down the voltage to take a PEDESTAL.
PEDESTAL RUN # : 5040029 taken. Chain-39 is giving "JUNK"(mean plot
is
completely dark).
12:40PM : PMD include in the run but showing higher dead time with compared
to
other detector. We talked to Tanko to mask that CRAM for the time being.
RUN # : 5040035 ~ 49K events
This run is good except chain-39
Took out PMD from the RUN.
2:00PM : Run # 5040040 ~ 5K events
Again Chain-39 is giving lots of JUNK.
There was controled access and Tapan bhai went into and took out the
LV
power for Chain-39.
PEDESTAL Run #: 5040060
Pedestal looks OK. Now Chain-9 got OFF(don't kno why?) Otherwise rest
of the
chains(whatever it was earlier) are fine.
7:15PM : Run# 5040076 ~ 2500 evts : Again it shows very high dead time.
Again PEDESTAL taken Run# 5040079 Sigma looks a bit high(May be now
beam
is there).
RUN # : 5040085 ~ 20K events. PMD had to go out of DAQ as it was giving
large deadtime and slowing down others.
For this run chain#19 was lighting up.
10:45PM: Run 5040107: Pedestal with BEAM OFF. The pedestal looks fine.
10:51PM: PedasPhys runs give large error, 100% deadtime but doesn't
stop.
11:12PM: RUN 5040111: Pedestal without Beam and with Full operating
voltage.
Problem in running 100% Error.
RUN 5040113: Pedestal running successful after rebooting.
11:27PM: We find that chain#19 is giving large values.
Turning off LV supply to Crate 5 (U6 & U7).
This takes out chains 18,19,20 and 21.
Run# 5041001 ~ 3500events taken. PMD gives high dead time.Took out from
the run.

In the middle of Run # 5041064 we recycled LVPS power of CRATE-3,4,5.
WE did this
because the initial few channels (~200) of most of the chains were
always firing up
with high rate. After recycling the LVPS the dead time got better.
8:20PM : SM-22 tripped at 1400V.
'productionLow' Trigger
Run # : 5041097 ~ 38K evts.
5041100 ~ 14.5K events.
Took out PMD for these two runs as 15,16,42,44,45,46,47 and 48 are

7:10 PM: PEDESTAL taken in the begining of beam.
RUN # : 5042066 (200 evts) & 5042067 ( 1000 evts)
We found sigma ( ~5-15) this is because of beam ON.
'productionMid' Trigger
8:30PM: Run # : 5042078 ~ 72K
'productionLow' Trigger
9:00PM: Run # : 5042082 ~ 80K
From the online plots: Chain25 to 29 is not working.
Since dead time increases so we recycled the LV CRATES in between the
run.
Run # 5042082 stopped after 80 K events because of frequently high
dead time of PMD. Few thousand evnets in the begining may not be good
because of recycling of low voltage during the data taking.
10:40 Run # 5042085 ~ 27K
The run started by recycling the low volatge.
Now there is not much problem of dead time of PMD. Rate is
also about 45 Hz as of the previous in which PMD was not included.
Run was stopped after 27188 events.
Run # 5042086 ~ 6880 stopped after 6880 events becase of TOF had 100%
dead time. PMD didnot give any problem.

help.
Then took pedestal RUN# : 5045036 at 500V and beam was ON. Pedestal looks OK. Started a new run again with 'productionLow' with PMD only @ 500V to make sure that PMD is not giving much junk. Runs fine. Dead time is low(35%). |

The mean and sigma plots completely messed up. The similar problem
had observed in Chain-25,26,27,28,29,30 15 days back. (See
the sample of one chain which has taken today). All the chains(CPV
,Preshower) are giving similar type of Pedestal plots.We susspect CLK or
CLR or may be due ot NIM CRATE problem. We recycled the power of
NIM bins several times but no change. PMD is not in the run.
What we did as suggested by Sushant(check the pedestal by powering LV crates one by one- 1.We switched OFF the LV CRATES and took pedestal, mean value is 35-45 and sigma is 0.5-0.6 @ 1000V. 2.Power ON LV crate-3 and took pedestal @ 1000V. Found the same problem as the above link . 3. Power ON LV crate-4 and 5 one by one, took pedestal @ 1000V and found the same problem. We will dig this problem on Wednesday(18th.Feb) access. |
|
7:30PM | There was some in the beam in the morning, data taking was there only for 4 hours. Around 7:30PM TPC gas system had some problem, so data taking had stopped. It started in the morning (17th.Feb)only for 1/2 an hour. |
10:00AM | In the 10:00 O'clock meeting, we told our problem about NIM bin. We requested for 1/2 an hour access today. Tonko told he will try for it but chances are less. If we will get controlled access we will bypass the fan in/out module otherwise will be done tomorrow. |
7:00AM to 4PM | We noted a problem with NIM-3 (it was giving -4.3V instead of -6.0V
with load). Crate is replaced with another NIM bin which was lying(marked
PMD) in the clean room. After changeing we took pedestal and back to NORMAL.
1.All the chains of Preshower plane has been debugged. We replaced some

controlled access and took out Chain 47&48 from Sec-1,Blk-1,Crams-11&12 . Also CPV Chain 1& 3 are presently connected . Rest ALL CPV chains were taken out of CRAMS as we suspected after discussion (with VECC people) that they maybe contributing to the dead time of PMD. |

5,2004
1st DAY of
|
WE (Subhasis
and Debasish) HAD ACCESS AND WE WORKED ON THE BAD CHAINS OF THE PMD PLANE(NORTH
SIDE).
We got lift and place to work at around 3:30PM after pole tip was retracted. We had a list of bad chains from last pedsetsla run during data
taking (63 GeV).
Before taking them we checked LVs on buffer board end for good chains to have some idea how they look like. After that we followed vanilla procedure of removing boards and see if DB still holds. for 25 >5 boarsd are removed to satisfy that. We are not sure if they are all bad voards, doubt is DB current limit is too low, and slight 'bad' also makes 'BAD'. ALL bad chains are fixed except 33. (33 was not in bad chain list, but
we see very low
chain 37 was connected to CPV side DB, when we connect that to one channel of Preshower side DB, it worked fine. We chnged the slots in CPV side DB, no where it took. Bad DB? too low current limit. We did not want to play with DB. We were in a dilemma whether to replace the bad boards with new ones,
and sort of decided
Chain 37 was finally connected to one of the preshower side DB taking
the slot of chain 25 (i.e removing 25). this was done after thinking that
25 is in the outer circle,
So, that's all for today. Will try to work on south side tomorrow. |

TODAY
WE DEBUGGED THE SOUTH SIDE OF PMD PLANE.
We took a pedestal (at 0V) in WAH and started to work.Today we debugged the chains from 39 to 48. We removed the 46th chain. The other chains which we could not debug was 33 and 35. The rest are OK. Debasish was on shift and a pedestal was taken at -1400V
except SM 20 OFF , SM-24 at -1200V.(7PM)Now another pedestal taken and
it seems that there is some STAR trigger problem . The peds dont look OK.

TODAY we dont have lift and SO we took
PEDESTAL( at 0V) once again in WAH.
We found that chain-30 OFF which we had debugged earlier on 5th April. So Subhasis went up in the late evening after we had lift from BBC guys and removed board-19 . Now chain-30 is OK. Now the final status that chains 25, 46, 47 and 48 are not connected. The chains 33 and 35 we wanted to debug but could not as BBC guys need LIFT and thats all for ACCESS. THE SCALERS are yet not fixed by Trigger guys and So pmd pedestal
taken with SCALARS out

Helen Caines the Shift Leader of morning
shift and debasish tried to debug trigger and rebooted STAR trigger 2 times
before taking PMD pedestal. Still scalars are out in PEDESTAL run.
The Chains in pedestal from 26 to 33 show OFF and LV connections for
those chains show 0 Amps.
Same status and no improvement. All those chains STILL SHOW OFF!!!. So Subhasis suggested to make HV of PMD plane to 0V as we could not understand and did not want to lose any more chains. So after the
PEDESTAL RUN #5101008 THE PMD IS PUT TO 0V and PEDESTAL TAKEN with
0V condition just to check the health of the chains from time to time.
rashmi and debasish took pedestals once again in evening and found chains
OK NOW!!!!!!

-do- | The pedestals are same as before and now
no more chains going bad. However after there was a RF problem and Helen
Caines reported a Controlled Access . Subhasis went inside to see the LV
state.
He reported that they are ON and BACK to life which is reconfirmed from the pedestal status. The pedestal taken and PMD still in 0V . |

PMD HV is put upto -1400V and BEAM ON
PEDESTAL TAKEN
and so HV remains -1400V till all PMD PP runs end. Improper Trigger as Pre-Trigger is not set properly according to Les Bland. This is the TRIGGER DETAILS OF Pmd TEST TRIGGER from Les Bland: The east(west) BBC is a scintillator annulus tiled by hexagons.
The
The BBC phototube currents are input to analog-to-digital converters
For p+p minimum bias events, the trigger is a coincidence between
the east
The total cross section of the p+p minimum bias trigger has been
measured
For run 5114023, the trigger used was similar to the p+p minimum
bias
THESE runs have PMD in but DO not HAVE the PMD TEST TRIGGER WHICH
After this PMD Gas bottle was changed as it was finished and HV ramped
down to 0V.
