RE: Question about IRRPROFI

Dear Niko,

1. All prompt results in FLUKA are per primary particle. Use of IRRPROFI
only if you want to make a delayed calculation, then the results will be
per second.
2. Use the IRRPROFIle card to create an irradiation profile defined in
one or multiple beam intervals. For each interval you have to provide
the beam intensity and duration. Imagine you have a pulsed source and
you want to define periods with beam on and beam off. For the beam off
period you have to define the length and set the intensity to zero.
Of course if you define an irradiation profile with only one interval
with zero intensity it would make no sense and will lead to a crash.

Vasilis

Subject: Question about IRRPROFI

Dear FLUKA experts,

Excuse me for the maybe dump question...

In the FLUKA online manual, as far as the IRRPROFI command is concerned
(http://www.fluka.org/fluka.php?id=man_onl&sub=44) it says that the
value 0.0 for the Beam Intensity is accepted.

Unfortunately, when I apply this value to my code, the program crashes.
So I have two questions:

1) I want the results normalized to 1 incident particle. Does the value
1.0 on the WHAT(2) field represents that ?

2) What is the physical meaning of the value 0.0 particles per second ?

Thank you in behalf,
Best Regards,
N. Charitonides
