Detailed Description

It generates gamma-rays using an uniform distribution.

This generator read a setup file ( setup/uniform.gene) to generate a cascade of gamma-rays. A template of such a file is available is the setup directory (uniform.gene.demo). Here is a snapshot:

#
# Ascii file that described the particle cascade shoot in a given event for ParisUniformPrimaryGeneratorAction
# This is a basic UNIFORM photon generator !! I.e. only gammas are allowed and each of them is emitted from the same source point
# The number of gammas per cascade is free but can not exceed 100 (see below)
# The first line gives information on the source position (x, y, z) in the lab frame (experimental hall frame) as well as
# its velocity components (vx,vy,vz) required for including Doppler effects (note that z is the direction of the beam).
# For sake of simplicity, the velocity components are given in units of the speed of light i.e. (beta_x, beta_y, beta_z).
# The second line gives the number of gamma to be shoot (multiplicity max of 100)
# The third line indicates the energy range over which the gammas will be randomly sampled as well as their emission cone
#
# source position and velocity/c

Warning
The multiplicity of the cascade is restricted to 100.

void ParisUniformPrimaryGeneratorAction::ComputeParameters ( G4String  filename = "setup/uniform.gene")

from a given file, it reads the characteristics of the gamma cascade

The parameters are read from a file which is by default setup/uniform.gene. In this file, the position . of the emitting gamma source, the angular coverage of the emission cone and the gamma energy can be modified
