Collect Beam Data for Detector Checkout
- Goal: Collect 5 days of beam data.
- Schedule: Oct 19-23 (starting at the end of the previous step, duration 5 days)
- Responsibility: Hall D
- Priority: High
- Prerequisites:
- Tagger Hall equipment installed and tested
- Solenoid current 1200 A
- Collimator in the "plug" position
- Target 10 mm HDPE plastic at nominal position
- Hall D detectors are ON
- Tagger Hall detectors are OFF
- Activities
- Re-establish 50 µA CW electron beam (Accelerator)
- Re-establish photon beam using 1.7·10-5 radiator
- Check the Tagger radiation levels. Turn the Tagger Hall detectors ON. Verify the tagger rates. Check the rates/levels with no radiator, 1.7 and 11·10-5 radiators.
- Move the collimator to the nominal position (5 mm hole) with the beam off, turn the beam on and adjust the beam position using the Active Collimator signals
- Perform PS wire scan
- Verify the trigger rate. Select the beam current (50-100 nA) and the radiator thickness (1.7-11·10-5) in order to optimize it
- Take data with the regular trigger for five days
