Different 16 16 aspects of beam target interaction are demonstrating in the example including 17 lo gitudinal profile of energy deposition, spectra of secondary particles,17 longitudinal profile of energy deposition, spectra of secondary particles, 18 18 spectra of particles leaving the target. The results are presenting in a form 19 19 of average numbers and histograms. … … 22 22 GEOMETRY 23 23 24 The Target volume is a c ilinder placed inside Check cilindrical volume.
