    Trouble with coda. Finally got it back to running.
    Q2 on Left spec tripped off. Reset.

    A plot of T5/T1 vs I is almost a perfect straight line, as expected. By eye, from the plot, it looks like rate(TRUE)/rate(T1) ~ 1.e-4. Comparison of T5 rate and T1 and T3 rates at 68 uA is consistent with a resolving time of 55ns.

    21:19 start run 2070, trigger efficiency run, all ps = 1
    21:24, reset ps to proper running values, start run 2071
    23:28 rf trip, accel. off to do a QE scan
    23:40 beam back
    great beam delivery
