Scalers

Date:

Time:

Blue Beam Current ( /10^6 ions):

Yellow Beam Currents (/10^6 ions):

Procedure : 

  1. Toggle Start/Stop switch at Bottom scaler to STOP position : This pauses all scalers
  2. Record the Scaler values, in the table below, especially the ones in BOLD face
  3. Hit red RESET button on bottom scaler : this Resets all scalers
  4. Toggle Start/Stop switch at Bottom scaler to START position : This starts all scalers again

Make sure Scalers have started counting again after you are done, otherwise execute the STOP->Reset->START cycle again.
