Daily Run Plan

Here are details of the daily run plan. See also the global Run Plan. The person responsible should ensure that a crew of experts is available for the shift. This schedule will be updated frequently by the Run Coordinator as the situation on the ground changes.


Daily Run Plan for PREX   (latest at bottom)
Date (2010) Shift ---------- Activity (Responsible) ---------- --- Status ---
03/19 day pump down; Møller, Compton, septum install; Q2 repair

Insert sieve. (Techs)

03/19 swing Beam restore (B-team) done
03/20 owl
  • Septum checkout (Michaels: Page when beam imminent & spectrometer ready)

also:

  • Initial look at low current cavity monitors (Zafar: Page when beam imminent & spectrometer ready)
  • Target alignment (Michaels)
  • VDC checkout (Michaels)
  • Quartz detectors checkout (McNulty, Wexler -- page when VDC tracks seen)
  • GEM checkout (Camsonne -- page when VDC tracks seen, if left dipole is operating)

All at 1-2 µA.
Scattered energy ~ beam energy = 1.063 GeV.
Quad settings:

  • Right arm:
    • Q1: dI/dP= 411.2474 Amps/GeV/c
    • Q2: dI/dP= 436.2014 Amps/GeV/c
    • Q3: dI/dP= 433.3897 Amps/GeV/c
  • Left Arm:
    • Q1: dI/dP= 419.8772 Amps/GeV/c
    • Q2: dI/dP= 435.6273 Amps/GeV/c
    • Q3: dI/dP= 434.9682 Amps/GeV/c
