    Shift Summary

    8:00 Shift starts with Karl's runplan to take data on NH3 short and long carbon targets for systematic studies. Starting at elastic momentum.
    9:39 Hall C change HWP to IN
    11:40 Finished all runs on short bottom NH3. Cycle LHRS back to elastic for runs on long carbon target.
    13:40 Hall C change HWP to OUT
    14:50 Finished all runs on long C12_40. As Ran planed, we cycle LHRS back to 0.8987 to take data on short bottom NH3 for those 6% separation points in the old runplan.
    15:45 Stop at 0.7464 to take dilution runs. Called in target experts to drain out LHe in the nose, and cycle LHRS back to elastic setting.
