Re: Question about IRRPROFI

Dear Nikolaos,

we have used IRRPROFI with WHAT(2) = 0.0 many times without any problem.
If the program crashes, it means there is something else wrong with
your input. Please send your input file, as well as the *.out and the *.log
files.

FLUKA results are ALWAYS normalized to 1 incident particle, independent
of your input.
The value 1.0 on the WHAT(2) field means simply 1 particle per second.

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

It means there is no beam in the time interval concerned. For instance,
you can have x particles/sec for one month, a two-days shutdown, and again
x particles/sec for another month: for the two-days shutdown period,
you assign WHAT(2) = 0.0.
