    keyword=The shift summary

    We started shift by continuing taking data in 5D(e*) kinematics:
    LH2 target + radiator, Veto ON, HRS angle 28.91, Calorimeter angle 30, distance 11.4, beam current about 4uA (to keep trigger rate below 2 MHz). Our goal is to collect Q=0.035 C.
    Run # 2336 start time 8:03 stop time:10:05 Total events 107441 Q=0.027
    We stoped the run, sinc the beam was unstable.
    Run # 2337 start time 10:06 stop time 11:06 Total events 45573 Q= 0.011.
    We turned Veto OFF and increased the currwent to 25 uA
    Run # 2338 start time 11:07 stop time 11:17 bad run, coda problem.
    Run #2339 start time 11:18 stop time 11:35, total events 229K Q =0.025.
    No beam between 11:35-12:10
    Run #2340 start time 12:10 stop time 12:31, total events 301K, Q=0.0255.
    Run #2341 start time 12:32 stop time 12:41, total evensts 29K, Q=0.007
    MCC lost control of IOC no beam.
    Run #2342 start time 13:03 bad run, coda crash TS2 not responding.
    Pedestial width was a narow, about 6, so it allowed us to increase the beam current to 35uA.
    Run #2343 start time 13:19 stop time 13:28, total events 301K, Q=0.0168.
    Run #2344 start time 13:30 stop time 13:33, total events 46K, Q=0.004.
    We increased current to 45 uA and increased calirometer threshold to 1400.
    Run #2345 start time 13:35 stop time 13: 44, total events 302K, Q=0.0223
    We check the spectra and found the pedestial width to be about 11.
    Run #2346 start time 13:45 stop time 13:56, total events 301K, Q=0.022.
    Run #2347 start time 13:55 stop time 14:04, total events 302K, Q=0.0215.
    Run #2348, junk we have problem with the target overheating.
    Run #2349 start time 14:10 stop time 14:23, total evenets 301K, Q=0.0215
    Run # 2350 start timr 14:24 stop time 14:29, total events 130K, Q=0.0117
    High voltage problem RCS unit 08/12
    Run #2351 start time 14:34 stop time 14:47, total events 302K, Q=0.028.
    Run #2352 start time 14:48 stop time 15:00, total events 302K, Q=0.0295.
    Run #2353 start time 15:01 stop time 15:12, total events 301K, Q=0.029.
    Run #2354 start time 15:14 stop time 15:26, total events 302K, Q=0.0295
    Run #2355 start time 15:26 stop time 15:40, total events 302K, Q=0.0293.
    Run #2356 start time 15:41 stop time 15:53, total events 301K, Q=0.0295.
    Run #2357 start time 15:53 stop time, see the next shift report.
