Re: Flux

Hello Roser,

Yes it is possible.
You have to use BEAM and BEAMPOS cards to describe as accurate as possible
de shape of your beam.

Then depending of your study you can define an irradiation profile with
IRRPROF card (with requested radioactive decay, cooling times and scoring
at those cooling times) or if your study is only interested in prompt
radiation, you have to remember that FLUKA expresses results per primary.

Example : you define a USRBIN card and request the calculation of
tracklengh fluence, you will get part.cm/cm3/primary = part/cm2/primary

Online with fluscw user routine or offline when drawing some plot with
flair or pawlevbin you can insert some normalization which make sense with
your beam flux and replace the "primary" with your actual value.

Hope it helps.

Regards.
Sebastien.
