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). … Continuer la lecture

Hybrid source: positrons distribution
(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 … Continuer la lecture
