Specific instructions for connecting from JLab's Hall D conference room:
- Turn polycon on if necessary (do it before turning the computer on)
- With the polycon, place a call at 199.48.152.152
- Press # to enable the polycom keypad, then enter the meeting id: 660743227 and #
- You may have to unmute the microphone: #*4
- Turn the computer on if needed
Beam and Hall configuration
- Beam energy expected:
- 11.55 GeV
- Solenoid:
- 1350A
- CW Beam:
- 250 MHz frequency.
- Range: 1 nA-900
- Chopper slit: TBD (assume C, since Hall C will be at 5-pass all the time)
- Standard current and radiators
- ~350 nA on a 4.1·10-4 R.L. radiator (50 μm diamond). (RSAD limit 500nA on 58 μm diamond)) Is this still valid?
- ~350 nA on a 33.7·10-5 R.L. AL radiator (30 µm Al). (RSAD limit 600nA on 30 µm Al radiator))
- Position Slow Lock on or FFB on (FFB doesn't operate below 50nA).
- Radiators:
- Goniometer radiators:
- Diamond TBD
- Amorphous 40 μm Al radiator (44.9·10-5 R.L.)
- V-wire (for TAC run).
- Amorphous
- 1.64 µm Al (1.86·10-5 R.L., see study)
- 10 µm Al (11.2·10-5 R.L.)
- 30 µm Al (33.7·10-5 R.L.)
- Goniometer radiators:
- Tagger quadrupole on (-4.2 A).
- Collimator hole: Default running: 5.0 mm.
- Targets:
- LH2 target: cryogenic target
