The electron detector

  • The electron detector is placed 5 mm above the primary electron beam. To check that, I forced the energy of the scattered electrons to be the one of the primary beam (E=1.165 GeV). The figure below demonstrates that the electron detector is effectively located above the primary beam (ignore the photon detector and scattered photons).

  • Then after restoring the scattered electron energy formula, 100 events are generated in the following figures:

  • A close-up on the electron detector

Scattered beam 4.gif ----- Scattered beam 2.gif


  • Now looking at some distributions and numbers. The simulation was run with the following inputs:
   Beam energy = 1.165 GeV
   Beam polarization = 80%
   Dipole length and height: 125cm x 4.125"
   Laser: 532nm, 1kW and alpha_c=35.28 mrad
