Dear FLUKA experts,
I have a question about the source_newgen.f user routine.
For the purpose of single event upset rate calculation in components of an electronics system in the irradiation room of a hadrontherapy facility, I implemented these components in the inside of a rack in a model of the IR using FLUKA. A 250MeV proton beam is shot at an angle of 60° at a 15mm thick steel plate which results in a radiation field of secondary particles inside this electronics rack, which is located slightly off-center of the beamline.
To calculate the SEU rate I need the HEHAD-EQ and THNEU-EQ fluence in these components. Since the components are very small compared to the dimensions of the irradiation room, a large number of primary particles would have to be simulated for a small error.
In order to get the simulation time down, my approach would have been to score the HEHAD-EQ and THNEU-EQ fluence at the outer shell of the rack and use these fluences as a source with the source_newgen.f for an in-detail simulation.
As I have never used it before, I would like to ask how I should setup the user routine.
Thanks in advance.
