- DRAFT Accelerator Tagger Magnet Operation Procedures(V. 0)
- DRAFT Accelerator Hall D Ion Chamber Functional Test Procedure(V.1b3)
- DRAFT Accelerator Hall D Ion Chamber Calibration Procedure(V.1b2)
Action Items
- Send Todd a geometry of tagger area, including the mapped tagger magnet field, for GEANT simulations (Richard). Sasha says he will do this
- Estimate rates and ranges of parameters needed for the photon beam tuning (Todd for accelerator; Elton, Hovanes, Alexandre for Hall D)
Agenda
- Announcements
- Electron Commissioning (Todd/Mike)
- The Hall D Beam Delivery Procedure is heading toward Rev. 10 with the feedback which was received.
- Ion Chamber Procedures are currently under review for release and use.
- Eugene/Curtis have been added as administrators for Hall D's Operational Restrictions[1]
- System Experts have been requested to write test plans for hardware commissioning of the nA BPMs, FFB system, and the Active Collimator.
- Is a Cross Calibration Procedure for absolute current measurement desired? (Between Faraday Cup 2 in the Injector and the Hall BCM)
- Need to identify the appropriate point of contact in Radcon to write the measurement test plan for fall (George K. or Pavel perhaps?)
- Regarding minimum deliverable current (open question from last time):
| Stripline BPM Resolutions | ≥ 30nA 100um resolution | < 30nA resolution suffers(position noisy barring additional filtering) | 3nA yields expected resolution ≈ 300 µm |
- Photon Commissioning Draft (Alexandre)
- Radiation monitors
