STAR Comments regarding Schedule for Remainder of
Run

• In general, it is always a good idea to put
  Physics running ahead of commissioning in any
  plan.
• Humidity control is not good in the STAR IR
• As one gets later into the Summer, the
  probability of encountering condensation
  problems, and hence not being able to run the
  Detector systems, increases.
• The magnet can run at higher Dew point
  temperatures than the Detector (70 F as opposed
  to 63 F).
• Given the above, from the Experiment standpoint,
  it makes more sense to run the 62 GeV period
  prior to the 500 GeV commissioning.
