Presentation transcript:

RHIC status Chuyu Liu Time meeting Apr. 28, 2015

Concerns  Vacuum breaks when moving components.  Aperture limit due to misaligned beam pipe.

Design orbit

Progress  DX magnets and other components move were done on schedule without incidents.  Blue and Yellow polarimeter change finished, Blue vacuum recovered after leak being fixed.  D0 polarity flip done. Current shut off tests were done for Au and proton injection.  Blue beam was captured, on design orbit, instrumentation setup at injection was done.  Yellow beam was circulating, capture is ongoing.  No aperture limit problem!!!

Blue orbit

Plan of this week  First collision on Saturday.  Thursday 5-6 hrs starting from 8:00AM, RHIC access, for PHENIX detector work and others.
