Revision as of 15:31, 17 July 2014

Expected duration: Approximately a few days.
Goal: Get electron beam to the dump in the tagger hall with acceptable radiation levels.
Responsibility: Main: Accelerator, support: HallD, RadCon.
Priority: High
Conditions:
- Tagger hall equipment removed. This includes the microscope (TAGM) and the electronics.
- Hall D controlled quadrupoles turned off.
- Initially pulsed beam will be used, then CW beam.
  - Although CW has not been delivered yet to Hall D, it is unlikely that CW will not be achieved for this commissioning period. We can reasonably assume in commissioning plan that CW will be available.
- No radiator installed.
- Collimator blocks the photon beamline to Hall D.
- Backsplash detector (if available) installed at entrance of collimator cave.
Activities:
- Tune beam to the dump, check the beam specifications (accelerator).
- Check radiation levels in the tagger hall (Hall D/RadCon).
- Check for photons (with backsplash detector) and radiation levels in the collimator cave (Hall D/RadCon).
