Circ Raster for GeN

Beam Parameters

The beam parameters submitted to the Hall A Accelerator Physics Experiment Liaison are posted to the SBS doc-db:130.

Data Analysis

  • Unser Calibration [1]
  • Unser and BCM Pedestal Calibration [2]
  • BCM Calibration [3]

    Cable Mapping

    The cable mapping for the beam line signals from the beam line racks 1H75B04 and 1H75B10 over to the SBS bunker and the LHRS are posted to the SBS doc-db:131.

    Target Lock Positions

    Target Lock positions for center of carbon hole as determined during the beam centering and raster calibration program for each beam energy. The beam positions should be read from BPM1H04A and BPM1H04E and should both be the same to get a low angle orbit coming in to the target. The SBS setting is the current in the magnet relative to its full nominal value of 2100 A. The sign indicates the polarity.
