In going over some runs I have done,
I want to make sure I have done the inputs correctly.
If I have an isotropic source incident down on a plate in
the x-y plane and I have the source a very small
distance above the plane, will the following statements in the source.f
file give me the isotropic flux incident on one side of the plate:
TZFLK (NPFLKA) = - FLRNDM(XXX)
XKPHI = TWOTWO * PIPIPI * FLRNDM(XXX)
TXFLK (NPFLKA) = SIN(ACOS(TZFLK(NPFLKA))) * COS(XKPHI)
TYFLK (NPFLKA) = SIN(ACOS(TZFLK(NPFLKA))) * SIN(XKPHI)
Next, since particles go only in the minus Z direction and since detectors will normalize results to one incident particle, will my flux
be 1.0 particle/cm^2/s integrated over the 2 Pi hemisphere?
That is, isn't my 4 Pi integrated flux equal to 2.0 particles/cm^2/s?
I hope this makes sense. I read the recent discussion on
fluence and current on fluka-discuss and I hope I understand it correctly.
