Dear User,
you are scoring the neutron fluence taking into account the factor
dt/cos(theta).
For scoring the number of particles crossing a surface, I did the
following steps:
* I create a boundary between two regions where I need to store the
particle number information.
** I activate the mgdraw routine (using the USERDUMP card) and I use the
entry BXDRAW (see the description from the manual here reported)
*** I store the data on a file
BXDRAW (boundary crossing dumping)
Argument list (all variables are input only):
ICODE : FLUKA physical compartment originating the call
= 19: call from Kaskad (hadrons and muons)
= 29: call from Emfsco (electrons, positrons and photons)
= 39: call from Kasneu (low-energy neutrons)
= 49: call from Kashea (heavy ions)
= 59: call from Kasoph (optical photons)
MREG : number of region before boundary crossing
NEWREG : number of region after boundary crossing
XSCO, YSCO, ZSCO : coordinates of crossing point
BXDRAW is called at each boundary crossing (if requested by the user with
USERDUMP, WHAT(3) < 7.0). There is no default output: any output must be
supplied by the user.
If name-based input is being used, the names corresponding to MREG and
NEWREG can be obtained via a call to routine GEOR2N:
