RHIC CNI Polarimeter Status

• All targets in blue have been scanned.
• Both blue and yellow polarimeters are working.
• They provide polarization information (in a
  relative sense) at injection at store.
• They also provide emittance information which is
  important for injection tuning.
• Operation instructions have been put out last
  week.
• There are still glitches that sometimes the
  system is not working. We are working
  aggressively to address these issues.
• The Si detectors used this year are different
  from last year. The dead-layer correction is
  different from the past.
• We are taking two hours today to study the
  effect.
• Software on ramp measurement is ready for test.
