Edinburgh group ion gauge turned OFF -> decrease in leakage current from 10.05 uA to 6.5 uA

GSI vacuum group ion gauge turned OFF -> decrease in leakage current from 6.5 uA to 3.63 uA

GSI large ion pump turned ON -> no effect on leakage current

Motors moved IN the same as elog 201. No significant increase in leakage current as moved further into the chamber (attachment 1). Pulser widths follow similar path as previous tests. Aida1 and 2 statrt with larger pulser widths which reduce as are moved into the chamber. Aida3,4 start lower than aida1,2 and remain at same level throughout. (attachment2)

RF ring signal removed from aida5. Data rate dropped back to ~20 kb/sec, Merger rate ~80,000 items/sec

Noise appears lower across all fees. Aida1 channels for asic 1 and 3 (noisiest) checked against elog 197, same channels are hot but at lower rate to elog 197.

On 15/2/22 it was noted that the leakage current increases when the motors are moved IN. This is contary to tests conducted on 12/2/22 (elog 192) where no increase was observed. 

16/2/22: Servo motor and pneumatic used to move in by different differences with leakage current observed to increase linearly with distance moved in, measured using the potentiometer. (attachment 10)

After each movement the pulser width was measured for each of aida1,2,3,4. No change observed for aida3,4 with pulser width ~220 channels. Pulser width decreased for aida1,2 when moved IN. (attachment 11)

Noise on aida 2,3,4 appeared low throughout tests. Aida1 has a large noise peak when in fully out position. When moved fully in, the noise peak disappears (attachments 1,2)

Cryring signals for ring RF, electron cooler voltage and schottky added to the motors signal and fed into mac b to be read in daq as aida correlation info #8 signal.

EMERGENCY SHUTDOWNS

1. CARME motors: Q key on keyboard while on workspace 1 of appc218 (right of this double-monitor setup)

2. Internal target: Q on keyboard while on workspace 3 of appc218, go to server room, press "CLOSE" button on DUMP.

CARME DAQ

CARME computer has 6 workspaces (WS), two monitors for each WS.

• WS1 : left monitor - fee power

          right monitor - fee power server

• WS2 : left monitor - DAQ controls

          right monitor - CAEN bias control

Most important tabs (right hand monitor)

• Run control : shows daq status, stopped / going
• Fee temperatures : temperatures of fees labelled aida01, aida02, aida03, aida04, aida05
• Statistics : shows the statistics for each fee
• System wide checks : checks for the setup
• Spectrum browser : loads histograms for fees and fee channels from preset layouts
• Asic control : sets asic parameters

• WS3 : left monitor - Merge control, tape server

          right monitor - servers, data being written

• WS4 : leakage current plot
• WS5 : online data monitoring
• WS6 : browser, elog
• Motors are running on second computer

TO DO FOR THE SHIFTERS - CHECK EVERY HOUR AND POST TO ELOG WITH SCREENSHOTS

-->IMPORTANT NOTE: MIDAS DAQ can respond slowly. DO NOT try to change tab or give new command while the previous one is being executed. Check activity in right-hand part of tab currently in use. Do not double click on buttons.

Motors computer (Computer to the right)

• Check motors cycle is running. The code will cycle through the loaded motors instructions. When an instruction is being done it is highlighted in bold. Check the bold highlighting cycles through entire set of instructions.
• Check potentiometer is reproducing same max/min values for each cycle of instructions. 74.02 fully in, 29.5 fully out.
• Detectors are on LEFT arm. Nothing on RIGHT arm which should not move.
• No need for screenshots, but record in the ELOG you checked this.

Merger, Tape server (WS3)

• Check NewMerger tab. Hit reload button and see if 'current links with data' and 'current merged data rate' are updating. All links should go green, but not necessarily at the same time. Keep hitting refresh until you see all of them going green at least once.
• Data rate should be around 100,000. Take screenshot.
• Check tapeService tab. Hit reload button. Check data rate in Kbytes/sec box. Record data rate to elog. This is where the current run number is displayed. Take screenshot.
• On the right-hand monitor, bottom right terminal, check the current run fragment (sub-run) is being written and is slowly increasing in size. It refreshed automatically every 5 seconds.

Leakage current (WS4)

• Check leakage current plot is stable. Make sure it is updating and time is correct. Take screenshot. Check present values on WS2, CAEN window, channel 1.

DAQ (WS2)

• Check Fee temperatures tab. Hit reload, temperatures will update and should all be green. 1-2 C above safe limit (top) is OK. More than that - warn expert shifter immediately. Take screenshot.
• Check system wide checks tab. Click on 'Check Clock Status', 'Check ADC Calibration' and 'Check the White rabbit decoder status' to run checks. Copy-paste test in the ELOG the first time you do it. If there are no changes throughout the shift, just record no changes.
• Check statistics tab. Hit Update All to see if the counter and rate are updating. Change counter being displayed using drop-down menu on the right hand side of the left monitor.
  • Good events - aida 1-4 should have similar counting rates. If any rate is a lot higher than the others, warn expert shifter.
  • ADC coincidence-info #8
  • Take screenshot of each for the ELOG
• Spectrum browser tab. Check it is displaying aida 1-4 rate (top right of each histogram). IF NOT: select layout 1 from 'layout ID' then restore layout from 'Arrange functions' drop down menu. Select log scale and change xmax as 128. This displays the data rate per strip. If any strips are a lot higher than the others, or very different from previous entry, make a note in the ELOG. Take screenshot.

Online monitoring (WS 5)

• Check the following plots are updating
  • LowEnergyXYTotal (right click - col - colz). This shows the total number of events, per pixel, since the code was started / re-started.
  • LowEnergyXYRate (right click - col - colz). This shows the rate over the last minute.
  • LowEnergyExTotal (double left click. Right click on y axis - Log scale on y). This shows the total energy deposited on all X strips since code restart.
  • LowEnergyEyTotal (as above). as above, Y strips.
• Please take screenshot of each

Alpha background gathered from 17:35 12/2/22 to 13:44 13/2/22 is run32. Run time ~20 hours. Some alphas visible in aida1 1*L histograms attached.

Noticed grounding of crimps that attched to cryring ground has come loose. Those crimps not ideal for our grounding cable so were loose. Grounding cable from each fee now meet at a single grounding cable joined by an m3 nut and bolt. This grounding cable then goes to the cryring ground and is properly secured. See attachment 1. No significant change to pulser widths with new grounding method from previous elog. 

Aida5 appeared non-responsive, no good events / data items etc and would not stop when daq was stopped. Fee power cycled. Aida 3 and 5 then showed no data items / good events or any stats. When stopping daq all fees then became non responsive. Full restart initiated, fee power off, all servers incl merger and tape server closed. Restarted system, all fees now responsive, all show full stats and are writing data. 

Alpha background started 17:06 13/2/22 to 09:41 14/2/22 is run35. Run time ~16 hours 40 mins.

> Bias increased to 140V, increase in leakage current ~0.2 uA, appears stable. Increase to 150V, fluctuate in leakage current of +/-0.5uA then huge increase to >20uA trip. 

> Fee power cycle. Bias 100V, leakage current 9.9 uA ~0.1-0.2 uA higher than previous but stable. 

no change to good events

1.8*L pulser widths aida1-4: 468, 350,311, 296

> Some decrease seen with new grounding, however main source of noise still apparent and any decrease seems insignificant compared to changes due to position movement. 

> Water pipes have been zipped tied so they no loger touch motors, no change in pulser widths or noise levels however.  

To test effect of the motors on the leakage current, they were cycled once per hour overnight at approximately 50 minutes past the hour. - attachment 1
Leakgage current was seen to decrease slowly overnight before flattening out.

At 11:25 This morning the FEEs were powered on. From this point on the leakage current was observed to start to increase. - Attachment 2
Note the time recorded by the pi logging the leakage current is approximately 2 minutes ahead of the FEE.

15:40 I notice again that powering on the FEEs causes a momentary increase in the leakage current. - Attachment 3
