    We have taken the 2.3GeV g2p production data with very high efficiency in
    he weekend.  We managed to take all the kinematics points in the plan and
    took
    one extra point (1.940 GeV/c) with 120 M data. 
    
    On Monday MCC changed the linac energy to 415 MeV. Chicane had been moved to 
    run 4. check details here:

    Melissa worked at T2 issue (rate is too high). The timing looks normal.
    She plan to test MLU in Wednesday.

    Vince worked on the raw data files overwritten issue.  We could not solve
    this problem. But the coda now can kill itself whenever it try to
    overwrite an exist file.
    
    Target group did another anneal. Might change the target material in
    Wednesday during the 10-hour-beam-study.
    
    Kalyan changed the 3rd arm position for taking elastic proton for the 1.7
    GeV beam energy. 
    
    Future plan:
    
    1) Once beam recovered, we will do harp scan, BPM calibration
    2) Then take optics data for 1.7 GeV 2.5T 90deg target field
    3) Restricted access on Wednesday during beam study. Do anneal in
    Wednesday, might change target material if needed.
    4) Do moller measurement in Thursday morning
