    keyword=Attempt to study T1,T2,T7. No T1.

    We wanted to take ~1Hz of T1,T2,T7 on R-arm to study these
    triggers, as agreed. Turned on R-arm magnets (setting 1 GeV,
    somewhat below elastic peak to avoid a huge rate, also left sieve
    slit in to further cut the rate). Then after run 1582 we turned on the
    R-arm scint HV and saw that T2 and T7 rates were 190 and 270 kHz
    resp, but T1 rate zero. Start run 1583 with ps1=ps2=ps7=65K.
    It adds 7 Hz to accepted rate. At 470K events into run 1583, we decide
    to turn off the HV on R-arm scint, because it makes no sense to run
    with T1 not functioning. Didn't figure out why yet. T1 seemed ok before
    lockup, but it has fallen apart. If there is ever an access, I'll check it. I'll
    leave the R-arm setup like this now: magnets on, sieve in, HV off.
