Blue Beam Current ( /10^6 ions):
Yellow Beam Currents (/10^6 ions):
Procedure :
- Toggle Start/Stop switch at Bottom scaler to STOP position :
This pauses all scalers
- Record the Scaler values, in the table below, especially the
ones in BOLD face
- Hit red RESET button on bottom scaler : this Resets all scalers
- 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.
