Tune Electron Beam
- Link to the accelerator test plan for electron beam commissioning (ATLIS)
- 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 HARP commissioned (necessary to measure 10^-4 beam halo).
- Hall D controlled quadrupoles turned off.
- Initially pulsed beam will be used, then CW beam.
- Although CW beam 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 subsequent parts that CW beam 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).
