I’m trying to setup a reverse monte carlo with GRAS for a given geometry. My choice for the RMC is due to the geometry dimensions, where the target is a CCD and much smaller than the full geometry.
What I’m trying to do now is setting up the simulations with monoenergetic electrons. Is that possible in RMC? I ask because from the user guide, the RMC accepts exponential or power-law spectrums, or a user specified spectrum. I tried setting up with the latter option, with the following form:
/gps/ene/type Arb /gps/hist/type arb /gps/ene/min 3.000E+00 MeV /gps/ene/max 3.000E+00 MeV /gps/hist/point 3.00 1.00E+09 /gras/analysis/adjoint/addUserDefinedPrimSpectrum e- 1.00E+09 1/cm2 Arb
When I run the simulation, I seem not to get any results, and there are no converges whatsoever.
In addition, I add the normalization factor of 1.00E+09 so I get a transmission efficiency for a given primary energy.
Is that the way to go? I’d really appreciate any inputs.
Thanks in advance.
