Problems and Solutions

  • Collimator Temperature is Rising
    • If the collimator temperature alarm goes off, call MCC and tell them to turn off the beam. Then call the RC.
    • Don't raise the temperature alarm limits on the collimator. If it's getting warm, something's wrong
    • Things to check:
      • Is the collimator cooling? Stripchart should show 5 for the water flow at all times.
      • Is the raster size correct? Correct size is written on white board.
      • Have the Raster quads (Moller quads) been set to the correct values? See strip chart called "RasterQuadsCheck" and scale back in time to look for changes to values
      • Are the bpms working? IPM1H04A and IPM1H04E XPOS and YPOS should read out nonzero numbers on the strip chart when beam is on.
      • Is the beam in the right position? See appropriate IPM1H04A and IPM1H04E XPOS and YPOS written on the whiteboard.
      • Is the HallATGT lock enabled? Call MCC and ask if the target lock is enabled
