• 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: 11.632 GeV (include synchrotron radiation losses, except for the Hall D ramp).
• Solenoid on at 1350A. Any field changes should be avoided if possible.
• Beam current: CW 1 nA-1.5 μA. 250 MHz frequency.
• FFB on or Position Slow Lock on (FFB doesn't operate below 50nA).
• Radiators:
  • Goniometer diamond radiators:
    • J1a50       (50 μm - 4.1·10^-4 R.L., 4×4 mm²) - old crystal - excellent rocking curve
    • JD70-100 (58 μm - 4.8·10^-4 R.L., 7×7 mm²) - new crystal - excellent rocking curve
    • JD70-105 (47 μm - 3.9·10^-4 R.L., 7×7 mm²) - new crystal - good rocking curve
    • JD70-104 (17 μm - 1.4·10^-4 R.L., 7×7 mm²) - new crystal - wider rocking curve - marginally usable
  • We also have one 10 μm Al radiator.
  • Amorphous
    • 1.5 µm Al (1.7·10^-5 R.L.)
    • 10 µm Al (11.2·10^-5 R.L.)
    • 30 µm Al (33.7·10^-5 R.L.)

• Tagger quadrupole on (-4.2 A).

• Collimator hole: Both 5 mm diameter and 3.4 mm diameter. Default running: 5.0 mm

• Target: LH2 target: cryogenic target
