About the source Time and Frequency
Hello everyone , currently i’m trying to run a simulation with a source of particles (e-), which i want to customize as following steps, pulses of 1 us width and frequency of 100 Hz, I have look up to...

Geant4 doesn’t operate that way. Each event is a separate entity, caused by one incident particle, like an electron. If your readout system is slow enough that each of your 1 us pulses appears as “one...

thank you mkelsey for your replay, when i didn’t found anything related pulses or time frequency, i expected that geant4 doesn’t operat like that, so if i get it write, i can creat...

In Geant4, you can set a time_zero to an event. See examples/extended/radioactivedecay/Activation : PrimaryGeneratorAction.cc, line 105 Read full topic

Thank you maire for the seggustion, bassicaly my goual is to acheave higher doses, thats why i want to deliever primeries into pulses, with highier frequency, i can do it with geant4 ,??? Read full...

Hej, since there is no concept of pulses/intensity in Geant4, we only know event-by-event, what you can do is to add a time profile to your initial particles which then you can store and use at a...

hello Pico, thank you, My appreciation, could you please elaborate more on how I can do it, an example which adapting similar things Read full topic

So, I’ m thinking something as follows: Running the simulation where your primaries have a defined time structure, something like: 3 primaries with starting time 0s, 1 particle with starting time 1s,...

Hi, @pico Sorry for pooping this old thread. Can you please share more details on how to sample sources for time profiles using GPS . I have two primary ammas per event set using /gps/num. I am trying...

Hello @kitu.utkarsh , this is how I modify their initial time. I am unsure but I think this would work even if you define more than one vertices. PrimaryGeneratorAction::PrimaryGeneratorAction() :...

Hi @pico, Thanks a lot for your prompt reply and for sharing the detailed method. Yeah, I am defining only one vertex with two primary particles, so I will try to extend it for my case. One more silly...

Say you have a frequency of 2Hz and one vertex: the particle for the first event will have a time 0.0s the particle for the second one will have 0.5s the particle for the third one will have 1.0s … My...

Thanks for the super clear explanation. Oh, I see. I was confused initially; I thought the particles in one vertex would have different initial times. So essentially, if I understand right, by default...
