keyword=Swing shift summary
1600 hrs: Hall moved to beam permit around shift change. MCC working on tune to the BSY. Waiting for call that beam is ready for delivery. Target operator moved target ladder to empty position in preparation for beam tune up to the Hall A dump.
1700 hrs: Still awaiting beam delivery.
New Right HRS kinematic settings 18.0 deg 2.175 GeV/c
New BB settigns 82.0 deg, current set to 518 A readback is 515 A. All else is the same
Left HRS settings are the same as yesterday.
1745 hrs: MCC called, ready for CW delievery. Begin target checkout.
1812 hrs: BeO optics check is good. Switch to He3 target and asked for 2 micro amp beam on 2x2 raster
1820 hrs: He-3 target in place with 2 micro amp beam and 6x6 raster. Rates on T3 of left-HRS is 2.1 kHz ... good spot++ check out.
1825 hrs: He-3 target with 2 micro amp beam with raster now at 4x4.
Rates are rock solid at 2.1 kHz ... good target aim.
Spot++ check out is very good.
1840 hrs: Target operator ran polarization NMR check 58.1% ... good.
1842 hrs: Restored production running at 10 micro amp beam. Thanks MCC for a good beam on target check out.
1914 hrs: New HAPPEX run started by Yawei.
2000 hrs: Having trouble with Right HRS CODA. Failing to take events. RC has come in to give it a look and decided next step.
2115 hrs: Control access by RC and Bo to look at the Right HRS signals and find the problem causing the T1 trigger to go in and out ... mostly out.
2200 hrs: Back to beam permit.
2202 hrs: 10 microA beam has returned and Right HRS T1 trigger looks good. A loose cable on the T1 trigger was found and corrected.
2312 hrs: Started a new HAPPEX run # 31426
2351 hrs: Started a new Compton Run # 17032
Beam has been relativity good. Too bad we lost 2 hrs to the trigger problem but that is the breaks. Best wishes Owl shift.
