Handing over beam between Operators, Beam Physicists, and Experimenters

Beam is handed to and from the experiment with the beam blocker in image 3 of the A1900 inserted. Experimenters control this beam blocker with the red User Lockout Beam Blocker insert and the green User Lockout Beam Blocker retract buttons.

Handing beam from the operator or beam physicist to the experimenter

1. Operator in Charge or Beam Physicist verify that the User Lockout Beam Blocker is inserted and put beam on the User Lockout Beam Blocker.
2. Operator in Charge or Beam Physicist inform Experimenter in Charge that beam is available on the User Lockout Beam Blocker with a primary beam attenuation of xxxxx. Beam Physicist hands key to Experimenter in Charge, if applicable.
3. Experimenter in Charge verifies the attenuation on the display in the data-U and retracts User Lockout Beam Blocker when appropriate.

Handing beam from the experimenter to the operator or beam physicist

1. Experimenter inserts User Lockout Beam Blocker.
2. Experimenter inserts wall plug and viewer to protect experimental setup if key is handed back to Beam Physicist for tuning past the beam blocker.
3. Experimenter in Charge informs Operator in Charge or Beam Physicist that the beam has been relinquished and hands key to Beam Physicist.

Note

The Operator in Charge and the Beam Physicists only relinquish beam to the Experimenter in Charge, whose name appears on the data-U display.
