General Information
- Expected Staffing:
- Run Coordinator: To be named
- Online Shifts: 3 persons per shift, one with solenoid training.
- Offline Shifts: at least two people looking at data written to tape.
- Coordination Activities:
- MCC meeting at 7:00am
- Daily run meeting broadcast on bluejeans 10:30am??
- Activity Priority
- High: Activity should be completed, contingencies in place for issues.
- Medium: Desirable to complete the activity.
- Low: Activity would be useful if time permits us to do it.
- Deferred Activity
- Installation of liquid hydrogen target.
- Installation of diamond radiator in goniometer.
- Running data at 1350A solenoid current.
Beam Configuration Parameters
- Energy of Beam. Expect energy ~ 10.5 GeV
- Current of Beam
- 4-10 microA with pulsed beam
- 100-200 nA cw
- Radiators
- 0.8 microns Al (0.9 x 10^-5 rad len)
- 30 microns Al (3.4 x 10^-4 rad len)
- 100 microns Al (1.1 x 10^-3 rad len)
- Targets. Diameter = 3.19 cm. The position of the target can be moved 12 cm downstream to 32 cm upstream relative to the nominal Hall D target position (60 cm downstream of the downstream end of the upstream solenoid endcap.)
- 10mm disk of CH2 (HDPE, high density polyethylene)
- 2mm disk CH2 (HDPE)
- CH2 (HDPE) cup of 2mm thickness for the 2mm-inner diameter and 7mm for the outer ring.
- 3.4mm C12 graphite disk
- Run schedule. Scheduled about 4 weeks of beam to Hall D between mid Oct and mid Dec, 2014
