conditions
Conditions
  • Drive e- beam energy: 250GeV
  • Undulator K: 0.75
  • Undulator period: 1.5cm
  • Length of undulator: 100m
  • Drift to target: 450m
  • Accelerator gradient and focusing: 50MV/m for beam energy <250MeV, 0.5T background solenoid field focusing; for 250MeV to 2.4GeV, 25MV/m with discrete FODO set.
  • OMD: Non immersed, ramping distance 2cm
    • 1)7T-0.5T and 5T-0.5T, the thickness varies from 15cm to 80cm in 5cm steps;
    • 2) the thickness fixed at 20cm, B0-0.5T, B0 varies from 1 T to 10T
  • Photon collimator: None
  • Target material: 0.4 rl Titanium, non-immersed
  • Yield is calculated as Ne+ captured/Ne- in drive beam.
  • Positron capture is calculated by numerical cut using damping ring acceptance window: +/-7.5 degrees of RF(1.3GHz), ex+ey<0.09p.m.rad,1% energy spread with beam energy ~2.4GeV
