Procedure 16
 
How to set the electron detector on the "garage" position ?  
  • First of all, the electron beam must be off (see Hall A run coordinator and call MCC operator) If it is not the case the detector will eventually be destroyed.
  • Slow control of the electron detector
    To perform operations on the electron detector. Open the MISC... screen from the main Polarimeter EPICS screen and then choose "Electron Detector". On this screen, active buttons appear in blue and readback values appear on a yellow background. This screen is also reachable, by loading the file ComptonElectron.adl located under the home directory of hacuser on the hac computer.
    1. Click on "garage" button.
    2. To make sure the detector is where you want watch the detector move on the TV screen (there is one in tha Hall A counting house and one in the back room). The switches readback must oscillate a little bit if the system is running properly.
