Detailed Activities
1. Prior to beam activities
Estimated time (3 -4 Shifts: 1 Day)
- With Radcon support, Hall D techs uncable and remove start counter from cryostat
- With Radcon support, Target Group secures target gas, inerts the target piping, and bleeds vacuum chamber to atmospheric pressure
- With Radcon support, Target Group removes foam portion of cryostat
- With Radcon support, Target Group removes foam portion of cryostat
- With Radcon support, Target Group removes superinsulation around target cell
- With Radcon support, Target Group removes target cell
- With Radcon support, Target Group mounts Carbon ladder in place of the gas cell
- With Radcon support, Target Group, Foam portion of cryostat is put back in place, vacuum pumps on
- With Radcon support, Hall D techs Start counter put back in place, cables attached
- With Radcon support, Hall D techs Target inserted into solenoid
- Survey adjusts position in solenoid
- Hall D techs Beamline assembled and pump
- Hall D techs Ramp up the magnet
2. Prior to beam activities
- Establish typical tagged photon beam
- Harp scans for the electron Beam (and PS)
- Initial detector check out
- Equalize CCAL gains (calibrate CCAL)
- TAC run
