#** <span style="color:red"> Perhaps install a plug in the 5mm collimator hole to decrease photon flux (1h)? Need to de-install the plug once test is done (1h). Need RadCon presence for work on the beamline (ARM not sufficient). </span>
+
#** Iterative procedure: 2h/days for 3 days.
+
#** After successful commissioning of the TAC, do a TAC run every few days (1h run + 1h target empty/fill operation). We will do it 4 times.
+
#*Physics production data with test diamond (50μm?) and 5 mm hole. We should run at least 12h to have enough data for publication and optimally 0.5 week (Justin S.). This assume 100% efficiency, 10<sup>0</sup>7 γ/s in coherent peak (=220 nA on nominal 20μm production diamond). Ratio of longit./transverse. data:50/50. Switch every 2 runs.

#** Before the end of this task, take a 4h empty target run with polarized beam. Can be done at the same time as a TAC run, to save 1h on emptying/filling the target.
+
#* Test effect of quadrupole on microscope data. Alex B./Alex. S./Todd S. Iterative work: 4h/days for 4 days over a week. Production data can be taken concurrently, but quad. test has priority. Need also to scan magnetic to find optimal configuration. Alex S. calculation indicates it is 20% above nominal set current of 3.2968A.

#* Thin diamond test and production (characterized thin diamonds will be available early March)
+
#**Install thin diamonds (Install between early and mid-March. 8h but opportunistic: done during beam down time).
+
#** Establish polarized beam with on the 3 thin diamonds. (Hovanes, Paul) 3 days
+
#**If polarized beam is succesfuly established, then:
+
#*** Take data with thin diamond and 5 mm hole . Expected time (Justin S.), same as for 50μm diamond run, counting these 50μm diamond data.

General Information

This document describes the run plan for the Hall D Spring 2016 run.

  • Schedule for the Spring 2016 run, updated for the delays due to arc 7 power supply and RF separator vacuum leak. (Original dates were according to the long term calendar)
    1. Dec. 12th-13th: Electron beam restoration
    2. Dec. 14th-Dec. 21st, 8am: Hall D Fall run. Hall A will be at 4 pass with relatively low current (10 to 20 μA)
    3. Every Tuesdays: 12h of beam study. Every Thursdays, if necessary: 8h of RF recovery.
  • Goals for the Fall 2016 run were.
  1. GlueX low luminosity data taking
  2. High luminosity trigger and DAQ tests.
  3. ToF checkout.
  • Revised goals for only 1 week of running during the Fall 2016 run are.
  1. Trigger and DAQ status check.
  2. High luminosity trigger and DAQ performance study.
  3. Checkout of new diamond(s) and of goniometer (para vs perp rate difference)
  4. ToF checkout.
  5. Enough data taking for global check out.


Runplan

  1. Re-establish electron and photon beams (assume 3 days).
    • Ion Chambers trip threshold must be set.
    • Tune electron beam with radiator retracted
      • Amorphous Radiator (and diamond) must be retracted. Collimator should be in blocking position. CDC/FDC are off
      • Radiation levels should be closely monitored by MCC crew.
        • Typical levels are (for radiator retracted, collimator fully blocking, electron beam current 50 nA)
          • RAD102_P1 ~ 3 mrad/hr (tagger area, gammas, between tagger and dump)
          • RAD102_P2 ~ 15 mrad/hr (tagger area, gammas, near electronics racks).
          • RAD102_P3 ~ 0.1 mrem/hr (tagger area, neutrons, near electronics racks)
          • RAD508_P1 < 0.1 mrad/hr (collimator cave, gammas).
          • RAD508_P2 < 0. mrad/hr (Hall. Neutrons).
      • Hall D tagger CARMS, Ion Chamber and BLM threshold for beam trips should not be changed without approval of Hall D leader.
    • Check bleedthrough level. 10min Hovanes. Hall A needs to be running
      • Beam magnetic separation during Oct. We expect no significant bleedthrough.
    • Establish good photon beam
    • Make sure tagger quadrupole is on (-4.2 A).
      • Insert 2*10-5 RL radiator. (Call MCC and ask to mask the FSD each time the radiator is moved)
        • Typical levels are (for 2*10-5 radiator, electron beam current 50 nA)
          • RAD102_P1= 2-10 mrad/hr (tagger area, gammas, between tagger and dump)
          • RAD102_P2= 40-50 mrad/hr (tagger area, gammas, near electronics racks)
          • RAD102_P3= ~2 mrem/hr (tagger area, neutrons, near electronics racks)
          • RAD508_P1= ~10 mrad/hr (collimator cave, gammas).
          • RAD508_P2 < ~ 0. mrad/hr (Hall. Neutrons).
    • Once radiation levels are good, proceed with harp scans (Hovanes/Todd. 15 min)
      • Take tagger harp scans. Check consistency with Accelerator's harps. Study beam focusing
    • Radiation level study (1h):
      • Run 5 min without radiator (Call MCC and ask to mask the FSD each time the radiator is moved). Beam current: 50nA. Repeat at 100 nA and 200 nA
      • Run 5 min with the 10-4 radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA
      • Run 3 min with the 3*10-4 radiator (Call MCC). Beam current: 50nA. Repeat at 100 nA and 200 nA
    • Active Collimator calibration. (20 + 20 mins)
      • re-Insert the 10-4 radiator (Call MCC). Use about 200 nA beam current. (This corresponds to the expected photon flux for standard production runs).
      • Determine maximum photon beam transmission by doing 2D scans (x: beam scan, y: beam scan. ±5mm with 0.5mm steps. Stay 5 seconds with stable beam for each steps Remind MCC that they should use only the last corrector (5C11A) to adjust the beam position. If the adjustment results in unacceptable e- beam position in the tagger dump, remind MCC that they should use the tagger magnet only to readjust the e- beam position in the tagger dump. Meanwhile, monitor the rate at the active target and rates (including coinc.) in the pair spectrometer.
      • Repeat procedure with 2*10-5 radiator (Call MCC) and 50 nA beam current.
      • In addition do x/y scans using the collimator x/y motions and check consistency (Hovanes. 1h)
      • Run fast calibration procedure with beam rastering
      • Record on the white board what is the profiler position corresponding to the center of the A.C.
    • Scan the photon beam profile with PS rates and collimator x/y motions Need to have procedure/code ready. Do we need to install the collimator plug?? (Hovanes ??h)
    • Verify with MCC that position slow lock is back on (locking on profiler and for values corresponding to optimal photon flux).
  1. Detector and beamline checkout.
    • L1 trigger tuning. Check new firmware (Alex. Somov. 3h). These tests will be continued later on and completed (3h+4h).
    • Reestablish DAQ (Sergei, 3h). Sergey to establish optimal beam current for DAQ (with 10-4 radiator). These tests will be completed later (3h).
    • General detector calibration (Sean Dobbs . 4h). Use 10-4 radiator. Call Sean when getting ready for this task (at any hour): (703) 887-1776.
      • At the same time, do Hodoscope voltage scans (Nathan S.)
      • Run 15 min in Long Mode.
      • Push DAQ performances by running with 15 min 15% above optimal beam current (as determined by Sergey above). Then run another 15 min 50% above.
  2. Realign old 50 μm diamond (J1a50). Later on, align at least one new 50 μm diamond (Hovanes, Paul Mattione. 12h/diamond).
    • ToF tests (Benedikt Zihlmann. 6h).
      • At the same time, do CDC voltage scans.
      • At the same time, do PS magnetic field scans. (Alex. Somov. 2h)
  3. L1 trigger test for high-rate performance tests (Alex Somov. 8h+8h. Use up to 1 μA. DC off if necessary)
    • Check rates for various beam currents and thr. settings.
  4. Run PS at lower B-field so that the TPol can check the low photon energy tail polarization. PS set-up so that it sees 3 GeV photons (Alex Somov/Nathan Sparks/Mike Dugger 4h/maybe parasitic?)
  5. DAQ high-rate performance tests (Sergei Furletov 2h)
  6. high-current mapping (Sergei Furletov/Alex Somov/David Lawrence 2h) plan
  7. L3 high-rate performance tests (David Lawrence 4h, 2h+2h, separated by a few days) plan
  8. Check bleedthrough level once Hall A is at 5th pass and RF separator is used (Nov. 1st) Hovanes. Hall A needs to be running
    • Need to assess level of acceptable bleedthrough
  9. Gluex data production
    • Tagger quadrupole on
    • Harp scans once a day: 15 min.
    • Empty target run every week (2h: 1- h to empty/fill back the target, 1h running). Standard production current.
    • Amorphous run. Every day. 1h Standard production current. Time to switch from pol. to unpol.: 10min. time to switch from unpol. to pol.: 30min.
    • TAC runs. 2 TAC runs (one at the beginning, one in the middle of the run). (Hovanes, Alex Somov, 5h: 4h run with thick converter. 1- h target empty+fill)
    • Physics production data with diamonds and 5 mm hole. Ratio of para./transverse data:50/50. 2h runs and no more, as it may be hard to correct for calibration drifts. Switch polarization every run. Time to switch: 10min. DAQ start run overhead: 3min.
      • Start run with old 50 μm diamond (J1a50). When new 20 μm diamonds is aligned, assess its quality and decide what diamond should be used. Possibly some running on new 50 μm diamond is its quality warrants it.
      • Luminosity:
        • Start at about 100 nA.
        • Then, once flux calibration is available from TAC, run at 107 photon flux.
        • Then, assess if we can run at a higher flux. (Paul M., to establish criteria of what flux we will be comfortable with, using e.g. accidental rate and/or detector aging).
      • Trigger configuration: First week: run in the same conditions as Spring 16. Then, evaluate if we can run at higher thr.
  10. Parasitic run for PrimEx detector: move ComCal close to the beam line and check rates.
  11. Parasitic TRD run
