Help Get More Beam Time

  • Provide someone to act as a guard when your hall is being locked up.
  • Provide a qualified ARM (Assigned Radiation Monitor) for radiation surveys.
  • Allow the operators at least 5 minutes before calling after the beam trips off. they are busy trying to identify and correct the problem.
  • Inform the Program Deputy in advance of all scheduled activities for the upcoming shifts. This allows the operators to prepare, and not waste valuable beam time.
  • Notify the control room of any configuration changes that may alter the beam orbit (i.e. changing the state of magnets, radiators, rasters, target cells)
  • Try not to schedule activities during the operator "passdown" periods. These periods occur for about 15 minutes at 0000, 0800, and 1600.
  • Try not to schedule activities during System Checks. System Checks usually occur at 1630 every evening.
