    This deviates slightly from the RC plan -- but I have his permission.
    We next go for p = 2.68 GeV on each arm (-2%) and will do a couple
    of short runs with He4 target, one with normal triggers, the
    other with S0 only.

    It took awhile for magnets to converge...

    Finally, start run 2181: Helium target with all triggers
    enabled.

    Next, we turn off S2m HV and set prescale factors ~infinite
    for all but the S0 triggers (T1,T3). Oddly, it seems that
    the S0 trigger rates increased by a factor of 2, but that needs
    to be checked offline (I don't think the beam current changed).

    Run 2182 with S0 only.
