I am shooting some beta electrons (beta emitter) to a slab of silicon to know the behaviour of a CCD and CMOS sensor. I've been using monoenergetic electrons so far but now I want to simulate a point source of C14. To do that I have to use GPS to generate a user defined energy spectrum (any alternative suggestion?). The problem is that I'm quite confused with the command "/gps/histpoint". I now that the first parameter is the energy (in MeV) and the second is the weight but I don't know how to use this parameter. I am trying to understand this with experiments but the more I do the more I am confused. I've been looking for in internet about this but everything I find are experiments, that don't fit with my situation, and the documentation that is quite poor in this aspect.
Can anybody help me? Thanks a lot, Jorge
