Current Status
- Jack, Ethan, Steve and Joe will stop working on HMS Q2 at 6pm, then we lock up. Hoping for working HMS Q2 tomorrow.
- Joe will meet with electricians tomorrow to order new part for rotation control and make plans to move it on an RF recovery day (takes about a day to install). This will hopefully resolve the rotation reset problems.
- Summary of runs from last night:
1) F2 tune at -5.925: runs 7158, 7159
2) Nominal tune at -5.925: runs 7161, 7162
3) Sylvester's radiator study: runs 7163 (out), 7165 (in)
4) Delta scan: run 7166@16deg, 7167@20deg, 7168@22deg
Current Run Plan
- x>1 optics study: Ep = -7.001, theta = 13.11 deg, normal tune (target: optics 1, collimator: "sieve", trigger: ps2=0)- 2 hours (over 180 K good e- events)
Instructions to monitor events:
1) do the 50 K replay (./run_shms.sh)
2) do root ROOTfiles/shms_replay_production_run_50000.root
3) do T->Draw("P.gtr.y>>h1(100,-5.,5.)","P.ngcer.npeSum>2.0 && P.gtr.dp>-12.0 && P.gtr.dp<20.0")
4) do T->Draw("P.cal.etottracknorm>>h2(150,0.01,1.5)","abs(P.gtr.y)<5.0 && P.gtr.dp > -12. && P.gtr.dp < 20. && P.ngcer.npeSum > 2.")
5) Look for the electron peak and cut on that
6) do h2->Integral(lowBin, highBin)
7) read the number and now project how many triggers you should take to get 180 K of e-

Instructions on how to set the F2 tune from nominal tune on magnets:
1) run the following: go_magnets_SHMS_F2 -5.925
2) click Go on Target

- F2 yptar scan: Ep = -3.3 GeV, theta = 21 deg, normal tune (target: LH2 , collimator: "collimator", trigger: ps2=0)
1) do the 50 K replay (./run_shms.sh)
2) do root ROOTfiles/shms_replay_production_run_50000.root
3) do T->Draw("P.cal.etottracknorm>>h2(150,0.01,1.5)","P.gtr.dp > -10. && P.gtr.dp < 22. && P.ngcer.npeSum > 2.")
4) Look for the electron peak
5) do h2->Integral(low,high) (where low and high are the bin numbers)
6) read the number and now project how many triggers you should take to get 450 k electrons
- F2 yptar scan: Ep = -3.3 GeV with theta = 19.85 deg, 21 deg, 22.15 deg, F2 tune (target: LH2 , collimator: "collimator", trigger: ps2=0)

- F2 positron run plan:
- Keep ELCLEAN rate <5 kHz
- TO will need to adjust the cryo load between LH2 and LD2!
- Use the F2 tune to set the magnets: go_magnets_SHMS_F2
1) 38 deg , Ep = +1.8 GeV , elclean statistics = 15 K on each target: LH2, LD2, Al dummy
2) 33 deg, Ep = +1.7 GeV , elclean statistics = 10 K on each target: LH2, LD2, Al dummy
3) 33 deg, Ep = +2.6 GeV , elclean statistics = 8 K on each target: LH2, LD2, Al dummy
4) 25 deg, Ep = + 3 Gev, elclean statistics = 3 K on each target: LH2, LD2, Al dummy
- If there is time, take more statistics!
- Sylvester's negative half of J/psi [1]
--> run at the last block of kinematics under "Setting scan" - 15 min per kinematic setting
Notices in Effect for Shift Crew
- If rotation cannot be Reset, call the RC, then call Ops for an escorted/controlled access.
