−
* Re-establish CW 1 pass beam to the Hall-B dump, setting beam to specified settings at the dump screen and the 2H02 harp. Chicane off. 5 nA.
+
* Call for seep and close the hall at 5pm
−
* Study the dependence of halo counter rates on beam position. Vary x and y of beam by +/- 7.5 mm, with beams parallel to specified settings above.
+
* Aid MCC to establish physics quality CW 1 pass beam to the Hall-B tagger dump:
−
Record scaler rates, BPMs, 2H02 harp, and beam location on dump screen. Choose nominal position close to rate minimum, at old nominal, if possible.
+
* When reasonable beam spot is achieved on the tagger dump screen perform harp scans, 2C21 and 2C24 (tagger) harps
−
* With beam at nominal, set up chicane to specified currents for the -7% field point. Instructions provided in Counting House. Verify harp scan and record
+
* If beam x/y sizes are ~<250 um, proceed with program below, otherwise ask MCC to retune   
−
location on dump screen. Tweak Frascati current if necessary, and record. Record scaler rates.
+
* Ask MCC to deliver oval beam at 2C24 (tagger harp x-width ~250 um, y-width << x-width, and tilt angle ~0
−
* Ditto for -9% beam position.
+
* Continue with 2C24 (tagger) harp scans to check oval shape beam tilt angle
−
* If little change in scaler rates, use -7% setting as chicane standard. If large improvement in scaler rates in going to -9%, try -11%.
+
* At 6 am on Friday, March 6, call MCC to sweep the hall and get it to restricted access.   
−
* Select standard chicane settings.
 
−
* Commission the HPS target, including measuring noise rates in the Ecal and halo counters vs beam current. Call Stepan before first use of target.
 
−
* With 1.5 um Pt target, measure scalers and Ecal occ vs beam current.Record Ecal Scalers and scalaer display for each beam current.
 
−
* If time allows, begin commissioning the Ecal and trigger with beam on target and data taking.
 
−
* Expect beam off Tuesday day shift for machine studies. Beam recovery starts on Swing.

Every Shift:

  1. Follow run plan as outlined by RC
  2. Keep shift summery up-to-date in HBLOG
  3. Document any beam condition change and send scaler GUIs to HBLOG
  4. Send "scaler_hps" GUI to logbook at least twice per shift or any time run conditions change
  5. Fill out shift checklist in the logbook, HBLOG, using template
  6. Continuously check quality of data

Every Run:

Run Plan:March 5 - 6

Setup Beam to Hall-B Tagger Dump and Studies of Beam Properties.

  • Call for seep and close the hall at 5pm
  • Aid MCC to establish physics quality CW 1 pass beam to the Hall-B tagger dump:
  • When reasonable beam spot is achieved on the tagger dump screen perform harp scans, 2C21 and 2C24 (tagger) harps
  • If beam x/y sizes are ~<250 um, proceed with program below, otherwise ask MCC to retune
  • Ask MCC to deliver oval beam at 2C24 (tagger harp x-width ~250 um, y-width << x-width, and tilt angle ~0
  • Continue with 2C24 (tagger) harp scans to check oval shape beam tilt angle
  • At 6 am on Friday, March 6, call MCC to sweep the hall and get it to restricted access.
