    keyword=Day shift summary

    8:00 continue with the production. There was NO beam at the begining of the Shift. The production for the Left arm is at: 2.2279 GeV 158 M Events required The production for the Right arm is at: 1.7348 GeV (Maximum allowed) 206 M Events required (2/3) of the runplan

    Mean while, we switch the target to the top 5.0T. Negative polarization.

    8:35 Beam back at 50 nA. Resume production. Target is at -69.6% polarization.

    9:20 MOLER STUDY Target move to home.

    MOLER PLAN:

    1. SPIN DANCES: at Wien angles -60.85, -75, -20,+20 degree, we measure the polarization of the beam accordingly. 100 nA 20 min/point at 1% accuracy 2. Measure polariztion at a single point which is picked for Hall C (priority)

    3. Bleed through Measurement

    15:40 Return to production. Start with the dilution Runs for Left arm production for the correct setting of the momentum.
