Hybrid source @ 8GeV: particles distributions after the crystal and after the amorphous

A 8 GeV electrons beam (composed by 1.1e+4 particles) impinge on a <111> oriented tungsten crystal of 1mm thickness.

Particles at the exit of the crystal

For display reason a cut is apply on px and py value (abs(px&&py)<20 MeV/c).

First case a transverse distribution of sigma=1mm is added to the particles transverse distribution

Electrons phase space at the exit of the crystal






Photons phase space at the exit of the crystal





Positrons phase space at the exit of the crystal






Second case a transverse distribution of sigma=2.5mm is added to the particles transverse distribution


Electrons phase space at the exit of the crystal


Photons phase space at the exit of the crystal


Positrons phase space at the exit of the crystal







Particles at the exit of the amorphous

The photons at the exit of the crystal is use to impinge on 8mm amorphous tungsten
(for 2.5mm rms value)
After the amorphous px,py and pz are defined by the following


Photons phase space at the exit of the amorphous






Electrons phase space at the exit of the amorphous






Positrons phase space at the exit of the amorphous
