(Robert Chehab’s graphic and summary)
In the following we took:

For both case (10 GeV and 5 GeV) the inital x and y electron distribution follow (ROOT syntax)

x=gRandom->Gaus(0,2.5e-3)/sqrt(2.); // gaussian centered x=0 with rms_x=2.5mm
y=gRandom->Gaus(0,2.5e-3)/sqrt(2.); // gaussian centered y=0 whith rms_y=2.5mm

Electron beam energy : 10 GeV

Crystal thickness : 0.1 cm
Distance between amorphous and amorphous : 2m
Amorphous thickness [...]
