I'm working on modeling a fairly straightforward scintillator hodoscope aimed at geophysical muon tomography of the type that Tanaka et al did with volcanoes in 2008 and 2009. One of the primary goals of the simulation is to characterize a relationship between internal resolution and integration time; as such I'd really like to do a time-dependent simulation where the particle injections were based upon functions of time, and the simulation was set to run for a set duration.
Based upon what I've read in the Application Developer's Manual, this forum, etc. It looks like this type of simulation is not very common; that it is more common to use normalization factors and the like for dosimetry calculations. However, I did note that it may be possible to use the GPS with a macro that made use of the /control/loop functionality. This seems like it would be clunky and very computationally-intensive, unfortunately.
My main questions are therefore:
1. Is it possible to assign each particle generated on/in a surface by a GPS object a unique starting time?
2. Any other suggestions for a time-dependent implementation of the General Particle Source?
Thanks in advance, -D. Hodge
