I would to simulate deep space radiation environment (GCR+SPE) using GPS for my application. I have got GCR proton flux from CREME and wrote the following macro for GPS and want to know if it is correct:
/gps/particle proton /gps/ene/type Arb /gps/hist/type arb /gps/hist/point 1.0023 0.0055595 /gps/hist/point 1.01623 0.023156 ... /gps/hist/point 100000 5.8474E-05
/gps/pos/type Surface /gps/pos/shape Sphere /gps/pos/centre 0. 0. 0. mm /gps/pos/radius 20. m
/gps/ang/type cos /gps/ang/mintheta 0. deg /gps/ang/maxtheta 90. deg
If it is correct, who can I normalize it? I have seen a couple of of other questions regarding normalizations and saw the files on http://geant4.in2p3.fr/2007/prog/prog.htm but it is still not clear to me in particular since I'm using arbitrary type . I would appreciate it if you could please elaborate on this or give a reference so I can read myself.
Also, from the previous topics in the space category and from GPS examples I learned that it is possible to have several particle source and simulate SPE at the same time. To simulate SPE, say the worst case, should I do it like GCR with arbitrary types? If yes is there a source for flux data?
Thank you very much in advance, Ali
