None A question concerning the event biasing

From: Olivier Dadoun <Olivier Dadoun>

Dear all,

I have an electron phase space input file for Geant4. The format of my file is the following:

x1(cm) y1(cm) px1(MeV) py1(MeV) pz1(MeV) N1

...

xi(cm) yi(cm) pxi(MeV) pyi(MeV) pzi(MeV) Ni

Where Ni is the number of electrons which have the same phase parameters (xi,pi).

To manage this I can inside my PrimaryGeneratorAction do:

particleGun->SetParticlePosition(x,y,0)

particleGun->SetParticleMomentum(px,py,pz)

and

particleGun->SetNumberOfParticles(N)

(and make a loop over all the file).

I would like to know if there is better way to proceed ? I though to the event biasing method (with some Weight for the particle considered) but I am not sure it is applicable here ...

Do you have any suggestions ?

By advance thank you

cheers

Olivier
