GANSourceDefaultGenerator

This class manage the base components of a particle generator.

class opengate.source.GANSourceDefaultGenerator.GANSourceDefaultGenerator(user_info)

This class manage the base components of a particle generator.

• In the constructor, the module ‘gaga’ is imported. It is only imported in the constructor to only required

this module if it is used

• ‘initialize’ function: the GAN is loaded and the list of keys is initialized

• ‘generator’ function: default generator

• ‘get_output_keys’ function: map the user defined keys to the ones of the generator. There are two usages, either

with on single primary (3 values for position, direction), or paired primary (6 values).

• ‘move_backward’ function: consider all particles positions and move their backward according to their direction,

using the factor provided by the user in ‘user_info.backward_distance’. This is useful to allow generating particles that do not intersect with the detector.

• ‘copy_generated_particle_to_g4’ function: copy all the particles (pos, dir, time, energy) to the cpp part.

generator(source)

Main function that will be called from the cpp side every time a batch of particles should be created. Once created here, the particles are copied to cpp. (Yes maybe the copy could be avoided, but I did not manage to do it)
