    keyword=Run plan for Sunday, owl+day

    Run plan Sunday, starting Owl shift 04/26/2009. (Xiaodong Jiang)

    1. Carbon multi-foil sieve slit runs, optics, momentum settings:
    Take T1 (on Right HRS) and T3 (on left HRS) only
    10 uA beam, unrasted.

    1.0 million trigger each run (or 10 min.), two runs each setting.

    i. Delta=+3.0% P_HRS=1.275
    ii. Delta=0.0%, P_HRS=1.238
    iii. Delta=-3.0% P_HRS=1.200, Call Brad in once this started.

    2. Brad take access, take down sieve slits, !!! Together with the holding plates !!!

    3. Set both HRS at 1.2205

    4. Pol. He3 in Longitudianal direction,

    Take elastic runs for 3-4 h, ask MCC to change beam halfwave plate half way in between.
    Take T1 (on Right HRS) and T3 (on left HRS) only

    Then, target polarization measurement.
    Rotate target to vertical, keep pumping.

    5. Reference cell N2 runs, with pressure 5, 10, 20, 30 psi, same HRS momentum,
    one run each in both arm, ~10 min.
    Take T1 (on Right HRS) and T3 (on left HRS) only

    6. Reference cell He3, pressure curve, same HRS momentum.
    pressure at 10, 40, 70, 100, 130 psi. one run each in both arm, 10 min.
    Take T1 (on Right HRS) and T3 (on left HRS) only.

    7. Return back to polarized He3, rotate target to Longitudianl, backward, 180 degree from
    step-4,
    Take T1 (on Right HRS) and T3 (on left HRS) only.
    Run for 3-4 h, ask MCC to change beam half wave plate half way in between.
