    keyword=Shift summary

    16:00 Swing shift start
    Septa heating tests underway
    - Took measurements of temperatures  
    when beam was at  (0,0), (-4,0), (0,0), (0,+4)
    The results are summarized in  log # 125469
    18:10 Beam off to take care of target software freeze.
    19:05 Beam back and target software issues resolved
    20:00 Finished with septa heating studies.
    20:20 Started new studies  Raster and Current scan 
    Target He
    current(uA)   8  15   22  30
    raster size (mm) 1x1   3x3   4x4
    22:30 switched to Target 12C
    raster on 3x3    current 30 uA
    raster off  and current 10, 30, 100
    23:10 finished the study.
    23:30 Start new study of septa heating with 
    a comparison of single foil C12 and Optics 12 cm 
    (double foil) target.
    with a current of 70 uA the difference in Septa heating
    was 0.05 K. Not significant! 
    We did not have the chance to try the dummy 20 cm.
    We wanted to know whether for the same thickness 
    in radialtion length as the He target and 
    in a double foil configuration we get the same 
    heating of the septa magnets.
    
    23:53 Q1 tripped. Requested access to the hall for reset.
    24:00 End of swing shift.
