keyword=beam qualityIn past one week from Mar 22 at 0:00am to Mar 29 at 8:00am, the beam
has been very stable. The first picture shows the beam central position
at entrance of ARC (IPM3C07.XPOS), the middle of ARC (hlc:MV_AI_DXPOS,
IPM3C12.XPOS), the exit of ARC (IPM3C17.XPOS), and width of beam
x profile at middle of ARC (hlc:MV_AI_DXWID). The second picture shows
the beam current. OTR x central position sometimes jumped about 0.2 mm while
BPM didn't move. The reason for that is still under investigation.
