AW: Question about IRRPROFI

Dear Nikolaos,

Question 1): The What2 gives the Intensity per second, giving 1.0 means
one particle per second. The intensity is important for the scoring, for
example when you are using DCYSCORE. N.B. that you still have to give
the number of primaries in the START card. This number determines the
number of sampled histories, while the intensity in IRRPROFI will give
the time structure and weight of the sampled particles.

Question 2): 0.0 particles per second has the meaning of no paricles per
second or in other words "beam off".

Cheers, Florian

Betreff: 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
