RC: Sanghwa Park


RHS optics data taking revisited due to wrong polarity setting for RHRS Q1. Took RHRS optics data with the correct polarity for a various magnet settings as requested and analyzers are looking at the data. After the optics data taking, Bob started working on coincidence timing. While trying the coincidence timing, had several issues; UPS problem ( - twice last night, LHRS Q2, Q3 current readback. Didn't see the coincidence time peak

  • Plan:
    • Take optics runs with Optics 1 and 2 targets
p0 = 1.104 GeV/c., Septum = 1100A
Q3: nominal setting, -10%
