Sunday Evening 17 Sept 2023
- Threshold study of Coincidence NPS DAQ
- Note meaning of following parameters
- FADC250_TET = threshold amplitude (0 to 4095) of single crystal signal to define a HIT. Current value 200 in file nps-vme.cfg
- VTP_NPS_ECALCLUSTER_SEED_THR = threshold of HIT integral (roughly 8x amplitude) converted to MeV to form a seed to look for multi-crystal cluster. Current value is 300 MeV in file nps-vtp.cfg Conversion factor from amplitude to MeV is FADC250_GAIN=1.0 in file nps-vme.cfg
- VTP_NPS_ECALCLUSTER_TRIGGER_THR = Threshold (MeV) of the sum of integrals in a cluster to define an NPS Trigger (hTrig1 in trigger display, and the input to the coincidence to form hTrig5 or 6). Based on Malek Mazouz' analysis of run 1181, expect the elastic electron endpoint of the NPS spectrum to be at roughly 3200 MeV (note NPS MeV units are currently arbitrary).
- Coincidence time window between HMS and NPS is 140 ns (visible on scope in electronics room)
- Sparsification is on (record only cluster waveforms).
- With Hydrogen target (PS3=0, all others -1) take runs of 25000 events as follows
- VTP_NPS_ECALCLUSTER_TRIGGER_THR = 500, 1000, 2000, 4000. When raw hTRIG1
- For each of these settings, take runs with VTP_NPS_ECALCLUSTER_SEED_THR = 300 and 600
- For each run, take note of the trigger rate of hTRIG1, hTRIG3, and hTRIG5, also calculate the estimated accidental coincidence rate = (hTRIG1 rate)*(hTRIG3 rate) *(140ns) and compare to hTRIG5 rate to assess True/Random coincidence ratio
- Expect hTRIG1 rate to drop near 0 at some threshold value. When it does, take a least one more run to find the endpoint a little more accurately
- Note meaning of following parameters
- Timing Study of NPS DAQ (requires an expert). Adjust the latency time in steps of 100 ns. The analyzed time distribution of hits of the true coincidence peak should move. This is proof of true coincidences. It is also possible to adjust the cable delay of 3/4 to push the true coincidences out of the lookback window.
- Take two runs (>10,000 events) at 15 and 7.5 muAmp. We can compare true / accidentals from rate scaling
- Take a long run ~2hour at the middle elastic angle of 15.76 (SHMS at 32.1 deg)
- Continue Optics (below)
Short Term Run Plan Saturday, September 16
- Following items when convenient (not yet scheduled)
- Beam Energy measurement
- Moeller measurement: Monday?
- BCM Calibration
- IA scan for feedback. This needs to wait until after we have been able to (roughly) calibrate the Hall C BCM in the parity DAQ (should be able to use the ion chamber calibration data for this). This should be coordinated with NPS and Moller polarimeter data runs to compare the asymmetry sign in the three systems. Estimated time is about 1 hour of beam.
- Establish the HMS-NPS coincidence. For reference, you may consult Section 2.2 of the Full Run plan. This part of the Run plan is expert-driven (Alex, Chandan, Simona and others)
- Move the NPS calorimeter to 12.12 deg. That's 12.12+16.3=28.42 deg for the SHMS.
- Check that the HMS is set at -4.367 GeV/c with the large collimator.
- Ask MCC for the NPS Sweep Magnet and compensation commissioning for this angle.
- NPS pedestal measurement: take a CODA run with the beam off. NPS HV and LV on. The goal is to get pedestal measurements for the NPS DC Anode current monitor.
- Ask for 5 microAmp beam on LH2.
- Take a HMS 3/4 only trigger run (PS3=0, all others –1). Take a short run (5-10 minutes). Verify that DC anode current (after beam-off pedestal subtraction) is less than 30 muAmp.
- Take a longer run.
- Check parameter FADC250 SPARSIFICATION = 0 in file nps-vme1:nps-vme/cfg/coin/nps-vme.cfg, to readout all waveforms
- Look on scope with persistence mode for true coincidence peak between HMS (PS3) and NPS (PS1) signals. Delayed HMS 3/4 signal marked H3/4 in top chan of PS752 logic unit (4th from right) in main NIM bin in rack CH03B06. This is currently (15 Sept) plugged into scope HCSCOPE01 chan 2. NPS (Trig-1) is 2nd chan PS752, plugged into scope chan 1.
- Analyse NPS Waveform data to find time spectrum of pulses. Look for true coincidence peaks.
- Analyse NPS Waveform data to verify VTP found all clusters.
- If all OK, take a 1 hour run with FADC250 SPARSIFICATION = 1
- Elastic Calibration of Calorimeter. Expected duration 13h. For reference, you may consult Section 2.3 of the Full run plan.
- Setup HMS : positive polarity p_HMS = +4.036. HMS angle =30.145 deg
- Set NPS calorimeter to 15.759 deg. That's SHMS at 15.759+16.3=32.05 deg.
- Use LH2 target
- NPS Sweep Magnet Off.
- CODA setup PS3=0, all others -1 (or possibly PS5=0, others -1 if the proton rate is so high as to create a lot of deadtime)
- NPS DAQ configuration:
- DTP cluster trigger threshold=500 MeV and readout threshold =100 MeV. The expert is Wassim Hamdi.
- check that VTP_NPS_FADCMASK_MODE = 1 (7x7 cluster readout)
- For each run condition below: check the anode current is less than 30 uA (using the GUI) and that the number of NPS clusters found per event is less than 15. The expert is Wassim Hamdi and he can check that for you. If necessary, lower the beam current and adjust the run duration. Also, check for saturation of FADC250 amplitude signals (no samples >4000).
- Take a one-hour run at 30 uA with the NPS at 15.759 deg (adjust beam current < 30 muAmp to keep NPS Anode DC current < 30muAmp).
- Take a one-hour run at 30 uA with the NPS at 14.673 deg. That's SHMS at 14.673+16.3=30.973 deg
- Take a one-hour run at 30 uA with the NPS at 16.965 deg. That's SHMS at 16.965+16.3=33.265 deg
- Now repeat for more statistics
- Take four one-hour runs at 30 uA with the NPS at 15.759 deg (adjust beam current < 30 muAmp to keep NPS Anode DC current < 30muAmp)
- Take four one-hour runs at 30 uA with the NPS at 14.673 deg. That's SHMS at 14.673+16.3=30.973 deg
- Take four one-hour runs at 30 uA with the NPS at 16.965 deg. That's SHMS at 16.965+16.3=33.265 deg
Short Term Run Plan Friday Sept 15, 2023
- Do not move either spectrometer without consulting RC
- HMS at 16.44 deg (was iced up last week), SHMS iced up today.
- Expect to be able to move NPS Calorimeter from 12.2 to 20 degrees. Start at 20 degrees
- Note: NPS calorimeter angle = SHMS set angle minus 16.30 degrees
- All data taking with coinc DAQ
- Initial standard equipment checkout.
- NPS Sweep Magnet and NPS HV off until start of coinc DAQ commissioning.
- Beam Centering on Carbon Hole hallcweb.jlab.org/wiki/index.php/Beam_Checkout_Procedures (Coordinate with Dave Gaskell).
- Take a short run with rastered beam through empty cylinder (tube) target. The goal is to see minimal change in the ion chamber readings when going through the tube.
- BPM Calibration vs. Harp Scan (Bull eyes scan) follow these instructions: [8]
- HMS detector verification. The relevant parts of the Run Plan (sections 2.1.6 & 2.1.7) are copied below. HMS nominal momentum -4.367 GeV/c. Start with 10 microAmp beam.
- Increase Q2 by +20% current compared to its nominal values to fully illuminate the focal plane. HOW_TO change the current in the HMS). Use LD2 target. Set HMS 3/4 prescale to keep event rate below 1000/sec (expect 2 : 1 prescale). All other prescales −1. EDTM rate 100 Hz (how to). Start with a 5 min run, then a 1 hour run, keep data files below 3M events. Keep the event rate low enough for near 100% efficiency . Analysis lead: Mark Mathison. Verify that all Hodoscope bars are counting and focal plane is illuminated. Check that timing spectra make sense. Contact expert(s) if in doubt. Verify that the events rate after cuts is close to expectations ( Zheng Huang).
- Return HMS-Q2 to nominal setting. Run for 1 hour. Use LD2 target. Keep prescales same as for the defocussed setting and record equal sized files. Expect 840 DIS events/sec at 10 microAmp on LH2 target.
- Take a 10 minute run with all HMS FADC channels in mode10
- PID (electron id) checkout with HMS momentum lowered to 3.60 GeV to keep pions below Cherenkov threshold (4.02 GeV/c)
- Run for 1 hour with PS3 ≥ 0 and PS4=–1. Check for clean Cherenkov distribution with selection of high energy signal in Shower. Check for clear single photo-electron peak with selection of MIP (pion) signal in Shower counter.
- Run for 1 hour with PS3= –1 and PS4 = 0. Compare Cherenkov signals of the two runs.
- NPS Sweep Magnet and compensation commissioning (Calo=20deg) for first look at calo signals while taking HMS optics data
- Initial Optics run: take a one hour sieve slit run (HMS single arm), HMS EL-REAL prescale (PS4) =0 and HMS 3/4 prescale(PS3) value 5 (HOWTO prescale values). Single target foil. Ibeam=30 uA (scale run duration if you cannot get 30 uA). Look at xfp versus yfp: the goal is to get at least 200 events per hole. This is how to put the sieve in position.
