Fall 2014 Commissioning Plan

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
  • 100-400 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.)
