Tune Electron Beam
- 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.
- 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).
