    Day shift 7/14/01: Calarco (SL), Zhu (TO), Savvinov, Urciuoli
    .
    8:05 Presently running runs 2018, 21018; program for the day is to keep running
    9:09 Ended runs 2018 (1.0M events), 21018 (0.9M events), 1182 (parity 150k events)
    9:12 Doing EPR measurement of target polarization (47.6%)
    9:15 Runs 2019, 21019, 1184 (?) started (what happened to 1183
    9:46 Charge asymmetry feedback not working ... see halog entry
    10:37 Ended runs 2019 (1.0M events), 21019 (0.9M events)
    10:39 Started runs 2020, 21020, 1185
    11:21 - 11:40 MCC lost track of charge asymmetry after beam trip (fast feedback
    was off for this time).
    12:04 Ended runs 2020 (1.0M events), 21020 (0.9m Events), 1185 (140k events)
    12:05 started runs 2021, 21021, 1186
    13:39 Ended runs 2021 (1.1M events), 21021 (1.0M events), 1186 (170k events)
    13:40 Beam off; moved target for NMR measurement (45.6%); MCC has beam off
    for a while (they say 20 min.)
    14:20 MCC giving us back the beam.
    14:24 Starting runs 2022, 21022, 1187
    14:44 Ending runs 2022 (0.2M events), 21022 (0.2M events), 1187 because we have
    re-evaluated the goal with the higher target polarization and find we now have more
    than the proposal goal.
    14.52 Half-wave plate in; MCC indicates that Joe Grames wants us to try the auto
    feedback on the charge asymmetry again ... so we will take a short run to see if it
    works.
    14:54 Starting runs 2023, 21023, 1188
    15:08 Ended runs 2023 (0.16M events), 21023 (0.19M events)
    1509 Started runs 2024, 21024, 1189
    15:28 Ended runs 2024 (0.24M events), 21024 (0.22M events), 1189 (34k events)
    15:31 Started runs 2025, 21025, 1190
    Thus endeth the day shift! May the gods of physics be with ye!
