Wednesday, November 1 (evening):
- Enter run #s on this sheet and add to binder at end of shift

Test for setting KinC_x60_4
1. Move HMS to 19.31 deg
2. Set HMS momentum to -5.052 GeV (electrons). This does not require going to MOL if HMS is initially at -5.253, just current setpoints.
3. Move SHMS to 31.39 deg (NPS at 15.09)
4. Target "out of Beam" request MCC turn on NPS Sweep Magnet to 468 Amp and tune Correctors following their procedure, starting from both correctors at 0.0 Amp.
5. If MCC tunes to non-zero correctors, then do the following optics test:
  1. Sweep & Correctors ON, HMS Collimator Sieve
    1. 30 min run: Target Carbon 0.5% , 30 uA, ps4=0, all other ps=-1
    2. 30 min run: Target Optics +/- 8cm , 30 uA, ps4=0, all other ps=-1
  2. Sweep & Correctors OFF, HMS Collimator Sieve
    1. 30 min run: Target Carbon 0.5% , 30 uA, ps4=0, all other ps=-1
    2. 30 min run: Target Optics +/- 8cm , 30 uA, ps4=0, all other ps=-1
  3. Sweep ON (Correctors on if needed by MCC), Restore HMS Large Collimator
6. Now two short production test runs. Label these in CODA and on paper KinC_x60_4
  1. One-hour run: LH2 target, 30 uA, ps6=0, all other ps=-1
    1. Reduce current if needed to keep Data Rate (CODA)<100MBy/sec, Event rate < 2 KHz, ps6 livetime > 90%
  2. One-hour run LD2 target, 15 uA, ps6=0, all other ps=-1
    1. Reduce current if needed to keep Data Rate (CODA)<100MBy/sec, Event rate < 2 KHz, ps6 livetime > 90%
Return to setting KinC_x50_4
1. Beam Off
2. Move HMS to 16.917 deg
3. Set HMS momentum to -5.253 GeV electron (this will require going to MOL)
4. Set SHMS to 30.69 deg (this is a 1 deg shift from prior KinC_x50_4 running).
5. Request MCC NPS Sweep on (468 A), tell MCC this is a prior setting in which we ran with Correctors OFF.
KinC_x50_4 data cycle (One cycle is ~10h of data taking at 100% efficiency). All ps=-1 except the unique trigger indicated.
1. For each current/target/trigger configuration, log rates, NPS anode currents, FADC trigger, and rad levels (see this example).
2. Event rates should be less than 2kHz in all configurations. The CODA Data rate should be less than 100 MByte/sec. Livetime should be above 90% and stable. The livetime can be read on the NPS FADC Scaler screen.
3. When taking production data (coin_sparse ps6=0), lower the beam current to obtain the desired rates and livetime conditions. Do not increase the ps6 prescale. If you can't obtain the desired conditions with a beam current higher than 4 uA, alert the RC.
4. Check that the NPS anode currents are below limits (limit shown on the anode current display).
5. Total run time should be adjusted for beam trip, but any given run should not exceed 1 hour.

Sunday Evening 17 Sept 2023

Threshold study of Coincidence NPS DAQ
1. Note meaning of following parameters
  1. FADC250_TET = threshold amplitude (0 to 4095) of single crystal signal to define a HIT. Current value 200 in file nps-vme.cfg
  2. 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
  3. 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).
  4. Coincidence time window between HMS and NPS is 140 ns (visible on scope in electronics room)
  5. Sparsification is on (record only cluster waveforms).
2. With Hydrogen target (PS3=0, all others -1) take runs of 25000 events as follows
  1. VTP_NPS_ECALCLUSTER_TRIGGER_THR = 500, 1000, 2000, 4000. When raw hTRIG1
  2. For each of these settings, take runs with VTP_NPS_ECALCLUSTER_SEED_THR = 300 and 600
  3. 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
  4. 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
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)
1. Beam Energy measurement
2. Moeller measurement: Monday?
3. BCM Calibration
4. 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)
1. Move the NPS calorimeter to 12.12 deg. That's 12.12+16.3=28.42 deg for the SHMS.
2. Check that the HMS is set at -4.367 GeV/c with the large collimator.
3. Ask MCC for the NPS Sweep Magnet and compensation commissioning for this angle.
4. 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.
5. Ask for 5 microAmp beam on LH2.
6. 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.
7. Take a longer run.
  1. Check parameter FADC250 SPARSIFICATION = 0 in file nps-vme1:nps-vme/cfg/coin/nps-vme.cfg, to readout all waveforms
  2. 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.
  3. Analyse NPS Waveform data to find time spectrum of pulses. Look for true coincidence peaks.
  4. Analyse NPS Waveform data to verify VTP found all clusters.
8. 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.
1. Setup HMS : positive polarity p_HMS = +4.036. HMS angle =30.145 deg
2. Set NPS calorimeter to 15.759 deg. That's SHMS at 15.759+16.3=32.05 deg.
3. Use LH2 target
4. NPS Sweep Magnet Off.
5. 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)
6. NPS DAQ configuration:
  1. DTP cluster trigger threshold=500 MeV and readout threshold =100 MeV. The expert is Wassim Hamdi.
  2. check that VTP_NPS_FADCMASK_MODE = 1 (7x7 cluster readout)
7. 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).
8. 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).
9. 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
10. 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
11. Now repeat for more statistics
12. 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)
13. 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
14. 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
1. HMS at 16.44 deg (was iced up last week), SHMS iced up today.
2. Expect to be able to move NPS Calorimeter from 12.2 to 20 degrees. Start at 20 degrees
3. Note: NPS calorimeter angle = SHMS set angle minus 16.30 degrees
All data taking with coinc DAQ
1. HMS `Single arm' data can be taken with PS3 and/or PS4 ≥ 0 (1:1) and PS5 and PS6 –1 (off).
2. NPS randoms can also be taken with PS1 ≥ 0: This trigger includes the EDTM
3. RunSheets
4. For online analysis instruction refer to [5]
Initial standard equipment checkout.
1. NPS Sweep Magnet and NPS HV off until start of coinc DAQ commissioning.
2. Beam Centering on Carbon Hole hallcweb.jlab.org/wiki/index.php/Beam_Checkout_Procedures (Coordinate with Dave Gaskell).
3. 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.
4. BPM Calibration vs. Harp Scan (Bull eyes scan) follow these instructions: [6]
5. 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.
  1. 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).
  2. 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.
  3. Take a 10 minute run with all HMS FADC channels in mode10
6. PID (electron id) checkout with HMS momentum lowered to 3.60 GeV to keep pions below Cherenkov threshold (4.02 GeV/c)
  1. 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.
  2. Run for 1 hour with PS3= –1 and PS4 = 0. Compare Cherenkov signals of the two runs.
7. NPS Sweep Magnet and compensation commissioning (Calo=20deg) for first look at calo signals while taking HMS optics data
8. 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.

Kinematic Setup Instructions

Be aware of the Current Angle Constraints on the SHMS and HMS: [7]

- Minimum angles: HMS 12.37; SHMS: 28.30;
- Minimum HMS-NPS Separation (remote) 26.70 deg = Minimum HHS-SHMS separation: 43.00 deg;

Be aware of the NPS Sweeper Setup

NPS sweeper setup
- Table of corrector currents for different SHMS/NPS angles: [8]: the nominal sweeper setting is 468A.

last update: 10-27-23. For now, send comments and corrections to C. Hyde

The Full Run Plan is available to you here for your information. That Full Run Plan is not chronologically ordered. The short-term run plan is outlined below and is regularly updated. The tasks on any given day are at the top of this page (above the line). The tasks below the line are outdated but are kept on this page for reference.

Saturday, October 28 (day) and Wednesday, November 1 (Day): kinematic KinC_x50_4

The NPS calo is at 3 m from the target
Set up the HMS to -5.253 GeV electron
Set the SHMS angle to 31.747 deg and the HMS angle to 16.917
expected DIS events on LH2 at 30 uA= 1.4 kHz.
duration= 5 days

Take the following data (One cycle is ~10h of data taking at 100% efficiency). All ps=-1 except the unique trigger indicated
1. For each current/target/trigger configuration, log rates, NPS anode currents, FADC trigger, and rad levels (see this example).
2. Event rates should be less than 2kHz in all configurations. The CODA Data rate should be less than 100 MByte/sec. Livetime should be above 90% and stable. The livetime can be read on the NPS FADC Scaler screen.
3. When taking production data (coin_sparse ps6=0), lower the beam current to obtain the desired rates and livetime conditions. Do not increase the ps6 prescale. If you can't obtain the desired conditions with a beam current higher than 4 uA, alert the RC.
4. Check that the NPS anode currents are below limits (limit shown on the anode current display).
5. Total run time should be adjusted for beam trip, but any given run should not exceed 1 hour.
6. LD2 Target
  1. Four 1-h runs at 15 uA, coin_sparse, ps6=0,
  2. One 20-min run at 10 uA, coin_sparse, ps6=0,
  3. One 20-min run at 5 uA, coin_sparse, ps6=0,
  4. One 20-min run at 15 uA, coin_sparse, ps3=2 (or as required to keep event rate about 2KHz)
  5. One 20-min run at 5 uA, coin_sparse_low, ps6 prescaled as needed to keep CODA Data rate less than 100 MByte/sec.
  6. One 10-min run at 15 uA, coin (SPARSIFICATION OFF), ps6 prescaled as needed to keep CODA Data rate below 100 MByte/sec.
7. Dummy Target
  1. 10 min run at 30 uA, coin_sparse, ps6=0
  2. 10 min run at 15 uA, coin_sparse, ps6=0
8. LH2 Target
  1. Two 1-h runs at 30 uA, coin_sparse, ps6=0,
  2. One 20-min run at 20 uA, coin_sparse, ps6=0,
  3. One 20-min run at 10 uA, coin_sparse, ps6=0,
  4. One 20-min run at 30 uA, coin_sparse, ps3=1 (or as required to keep event rate about 2KHz)
  5. One 20-min run at 10 uA, coin_sparse_low, ps6 prescaled as needed to keep CODA Data rate below 100 MByte/sec.
  6. One 10-min run at 30 uA, SPARSIFICATION OFF, ps6 prescaled as needed to keep CODA Data rate less than 100 MByte/sec.
9. Repeat the cycle above until a change of kinematic.
