    Shift started with kin #16 C for HRSL (moving on to B and A)


    08:45 calorimeter measurement
    09:38 move to 4cm dummy target
    10:31 start switch to kin #16 B (p=-0.3138 for HRSL)
    10:32 calorimeter measurement while switching
    11:28 move to LD2 since rate with dummy (#3608) is small (see @)
    12:34 start switch to kin #16 A (p=-0.3579 for HRSL)
    12:36 move to dummy target
    13:05 move to Ta target
    13:28 move to C target
    14:05 calorimeter measurement

    (*) Runs #3602, #3603, #3604 (and corresponding HRS R runs) are
    high-deadtime test runs with twice lower beam current (5 uA)
    and ps6=1 instead of ps6=2 (and 10 uA) as in run #3600.


    (@) Terminated dummy target runs #3608 / #21882 at 0.5M counts
    in HRSL which had ~ 300 Hz of T6. Runs #3609 / #21883 with
    the LD2 target have roughly the same rate of T6, so keeping
    in mind the factor 6 in Aluminum thickness, we should be OK
    (S/N of about 10:1) if we get ~ 1.0M events with LD2.
