no helium between VT2 and MT

We realised that the aquarium ("sac") between VTPC2 and MTPC hut was not filled with helium before this (p+Pb) run. We decided to leave it like that in order to keep constant conditions during the data taking.

measurements of the time of beam counters

I checked on the QA the counter histograms, and realized the missing time information for S11-S12 ans S11-S2.
The S11-S12 was a contact problem.
The time of the S11 is changed relative to the pPb run, because of the smalest HV on S11. I took out ~8ns cabel from the stop signal(S2)
and the measured value gone back to the time window.

Warning up VTX1 magnet

Starting from 26.07.2012 we measured the resistance of the magnet using 10A generator, and the the measured voltage drop on the coil it was 0.720V. The coil was separated from the converter. This situation was until 30.07 Morning, when Yves Gaillard installed an other power-converter and we found .86V at 100A. After this installation we remeasured with the used equip at 10A and got 0.15V.
we started at 11:30 100A continuesly.

VTPC-2 sector 2 issues

Mon, 5.09.2016 12:25:33

VTPC-2 sector 2 amp meter

VTPC-2 sector 2 current meter appears to be broken.

We tried to apply 100V to the chamber. Power supply tripped.
We tried two other channels at the power supply - still tripping.
We disconnected the TPC cable from the current meter, and the power supply was still tripping.
Finally we disconnected a cable connecting the power supply to the current meter (at the current meter), and then it did not trip.

We have no spares. We need to look for a replacement, or a new unit.

VTPC-2 noise oscillations understood!

From the beginning of the restart after the long MD a noise (oscillations) in the VTPC-2 sector 3 were observed. The reason was not understood. Many actions were taken mainly related to the LV crates (some listed below not in chronological order)
1. Carts 53 and 54 were replaced by spare ones
2. Displacment of the cards 52, 53 and 54 to the right side of the crate
3. Change of the top crate power supply
4. Swap of the powre supplies between the middle and top crate
5. Change of the power supply in the middle crate
6. A lot of power cycles
7. Contact-cleaner on the connectors ob the VT-2 Gating Grid (this made sense!)

None of these action really solved the problem in long term

The problem was understood by midnight 04/09 only.
The source of the problems are the transmission lines from the GG pulsers to the Gating Grid!
We (SP, OW and WD) entered to the VT-2 magnet from the top, found the GG lined Patch Boxes (only three of them are directly accessible - 1, 3 and 6; the other are hidden under the floor on the electronics). We shaked the boxes (contacts on the connectors and the placement. NOTE: the boxes are laying free - their are neither grounded nor isolated!
It helped for sector 3, but the sector 1 bezame a little noisy (sector 6 as well). It is better now, but we should still improve and stabilise the technical aspects of this (contact-cleaned and grounding(?))
We should do this by the next SPS break.
In the quiet time, when the floor over VT-2 can be removed all patch boxes should be checked and corrected!

VTPC-2 HV

In the night (4AM) the currents in VTPC-2 increased to 80nA (sector 1). We decreased HV by 200V. It didn't help much.

In the morning (10-11AM) we realised that the sector 6 was completely off: when changing HV there was no charging current visible. After disconnecting and connecting all connections: at the power supply, the current meter, the patch panel at the rack and at the TPC the problem is fixed.

VTPC-1 LV interlock

The temperature of the VTPC-1 LV interlock jumped up around 2AM, and then it was increasing slowly. As we already had problems with incorrect temperature measurement at the beginning of run, I tried to do the same what was done that time: I tried to touch cables in VTPC-2 sector 2. I did not observe any effect. Finally the interlock turned off LV. The temperature went down.

Restarting LV required reloading PCI kernel module and restarting EPICS server.

VT-2 noise fighting - story continues

During the SPS break an attempt to cure the noise (oscillations) in the sectors 1 and 6. Action:
1. contact-cleaner was put on the patch-box 1 and 6 connectors and on the box itself
2. Boxes 1 and 6 were wrapped with copper cord and connected to the ground
3. Boxes positioned to get the best possible contact with the top plate of the VT-2

On the pedestals taking seems that it helped. Should be confirmed with real data

Now A2 detector ADC (on channel 18) looks OK (good correlation with S11).
Had to lower the voltage of BPD-s (original settings: https://na61db.cern.ch:8443/elog/Experts+logbook/101130_004125/id52-2010-11-30-004044.png), as we were asked to do so.
Moved BPD voltages back.

The data was taken in two parts. The first one we change the distance od one of part of colimataor from -40 to 15mm and the second part was always at 40. The second time we change the distance of second part of colimater - the firs one was at -40, The distance for second colimator was from 40 to 10 mm. We mesuerment the counts from H2A_expt02 -C11 counter - and the I from beam monitor. The histograms are made like counts/I in function of distance.

Temperature in the MTPC hut

Temperature sensors

In the MTPC hut, the temperature in all sensors showed around 21 degree Celsius, except of MTPC-R Jura and MTPC-L Saleve. We realised these sensors were touching the metal construction of the TPC on the top. It also turned out to be very sensitive to the temperature of the electronics. For a test we unglued the MTPC-R sensor, and left it floating in the air. Now its temperature is around 21 degree also.

29.10.2014 15:18:09 The "MTPC-R Jura" sensor is attached back to the metal part of the TPC.

TPC, T0, T-offset

- New relative T0 calibration with pulser is possible within full detector except GTPC with 512 time bin mode with run 10363.

Previous attempt was also made, see https://na61db.cern.ch:8443/elog/Experts+logbook/2 E-log page.

TPC, T0, T-offset

- Relative T0 calibration is possibble within individual TPC volumes with pulser calibration data. This was recorded for all TPC-s, except for GTPC: run 10213, 10216 (https://na61db.cern.ch:8443/elog/Run+summary/4841, https://na61db.cern.ch:8443/elog/Run+summary/4842). For GTPC, pulser connection has to be built.
- Relative calibration of TPC-s is possible with measuring the time difference between the first SCA clock edge appearing on FEE cables, on reference FEE cards. Relative T0 correction of TPC volumes:
* VTPC1, SECTOR2, PADR12, PAD1 ..32 (reference): +0ns.
* VTPC2, SECTOR2, PADR12, PAD1 ..32 : -116ns.
* MTPCL, SECTOR1, PADR6, PAD1 ..32 : -20ns.
* MTPCR, SECTOR6, PADR1, PAD1 ..32 : -22ns.
* GTPC, SECTOR1, PADR1, PAD65..96 : -118ns.
- Global calibration of TPC T0: this means only an y shift of the TPC image. Can be obtained from correlation of fitted main-vertex and BPD main-vertex.

TPC drift voltage 5kV

I increased TPC drift voltage to 5kV.

I realised that in the GAP TPC there is no current visible on the power supply. Maybe for GAP TPC cable was disconnected from the TPC?

Fri, 4.11.2011 17:04:52

TPC drift voltage 1kV

Set the TPC drift voltage to 1kV.

The reason for the problems with switching it on before was that the HV cables were not fully plugged into the power supplies.

TPC drift voltage

The TPC drift voltage is set to 5kV in all 5 TPCs.

It has been set to 1kV earlier today, but elog was not operational due to the power cut in the small counting house.

---=== Update ===---
Realised that the current is equal 0 in all TPCs. Also DCS measures no voltage. Maybe the cables are disconnected from the TPCs? Turning the drift voltage down to 0 just in case.

Many DAQ crashes were encountered. Therefore, I applied contact spray to the ECL cable connectors of clock and trigger cables. 2 MTPC modules were not easy to access: they are left untouched now.

Still the number of crashes due to trigger skew is quite frequent.

Fri, 9.07.2021 12:11:33 Removed 50 Ohm termination from calib pulser and connected it to a pulser channel - RMS noise @ 1.6 (inner) - 1.9 (outer)

Fri, 9.07.2021 13:44:49 Everything connected, GG and calib. pulser also, but HV not connected - RMS noise @ 1.6 (inner) - 1.9 (outer)

Fri, 9.07.2021 13:50:52 Everything connected, GG and calib. pulser and HV also - RMS noise @ 1.45 (inner) -- 1.7 (outer)

Fri, 9.07.2021 13:57:25 Everything connected, GG and calib. pulser and HV also, disconnected potential strips on sector 6 - RMS noise @ 1.6 (inner) -- 1.85 (outer)

Fri, 9.07.2021 14:15:02 Everything connected, GG and calib. pulser and HV also, potential strips on sector 6 reconnected - RMS noise @ 1.4 (inner) -- 1.6 (outer) WHY?

Sat, 10.07.2021 22:14:54 In addition to noise we have some periodic pick-up which increases the RMS

Sat, 10.07.2021 22:16:07 Got better after checking the proper connection of grounding wires - RMS noise @ 0.9 (two FECs connected with old adapters), but later went to RMS noise @ 1.1 (after connecting 2 additional FECs) - can be coincidence

Sat, 10.07.2021 22:23:07 Conclusion: two tests: 1) check the influence of number of FECs connceted, 2) try the better grounding

Promptly dropped voltages in MTPCL High Res by 200V. Sector 25 continued running at 200nA, so further dropped it to 500V. (620 below nominal). Running currents appear to have subsided. Raising voltages back in small steps.
Mon, 11.11.2024 14:24:13 BL: TPCs (including MTPCL Sector 25) appear fine, but beam intensity is really low. Dropped all TPCs down to 300V below nominal (beam expert thought 200V wasn't safe enough) so beam expert can tune the beam.
Mon, 11.11.2024 22:30:40 BL: Brought TPCs up 100V, now at 200V below nominal. Beam intensity has changed again after recent LHC filling so waiting for additional beam tuning before proceeding higher.
Mon, 11.11.2024 23:18:28 BL: Brought TPCs back to nominal in small steps. Out-of-spill currents seem good.

Mon, 18.11.2024 08:29:11 BL: MTPCL Sector 25 tripped at ~6:40am this morning after high intensity beam. Currents were running 1.4-1.6uA in a similar fashion as previous instance until the power supply (trip set to 1.6uA/5s) killed the sector voltage after many minutes. Brought sector back up to nominal in steps, appears fine. New trip set to 1uA/10s.

Wed, 20.11.2024 21:35:19 At approximately 8pm, we received an extremely high intensity beam from SPS (S1 ~5M). Currents in VTPCs hit 4uA. To enable beam tuning, TPC HV was turned down by 200V and we are now raising it back in small steps. VTPC2 current trip setting was lowered from 5uA to 3uA. (I think the trip time is still 5s)

TPC HV up

Since yesterday evening we're slowly increasing chamber voltage. Now at 900V in VTPCs and 800/900V in MTPCs.

Wed, 11.08.2010 19:05:26

TPC HV tripped

Almost all TPC sectors tripped, except of VTPC-1 sectors 4 and 5, and some sectors in MTPC-R. BPDs tripped also.
-> Power supply problem (it trips even if the cable is disconnected). Rainer is arriving.

20:30 Solution is found. Accidentally the current limit for all channels in the CAEN power supply was set to 10nA. Now the original settings are restored and we could turn on all TPCs, BPDs, counters, potential strips (they tripped also).

Chamber voltages are 30V below the nominal value. I'm afraid to go higher, since I have no tool to verify the results (DAQ crashes a lot).

GAP TPC 150V below the nominal value. This is because occasionally I saw beam particles saturating ADCs of several adjacent pads.

Fri, 13.03.2026 17:56:52 At 17:23, began raising GRC voltage as well from its parking value of 1100V, toward nominal 1600V.
Sat, 14.03.2026 18:47:51 During the final raising to nominal, it was discovered that FTPC1 was not actually connected. Had to turn off all FTPC1 voltages plus FTPC2+3 sense wires in order to connect them. FTPC2+3 were raised back to normal relatively quickly, but since FTPC1 had not actually been stressed yet we had to raise it slowly.

Wed, 18.03.2026 07:44:17 In preparation for power cut in EHN1, all TPC voltages and power supplies were turned off.
Wed, 18.03.2026 14:04:54 TPC drift voltage and gating grid were turned on before lunch. Now raising TPCs (and GRC) back to nominal sense wire voltages gradually in steps.
