I just made a test with an irradiation profile of 30 intervals and it seemed
to work fine (FLUKA did not crash and it produced results).
In any case, for the application that you describe I'd propose you to study
the micro and macro structure of your irradiation independently. Isotopes
that significantly decay in 2.4 microseconds (between two pulses) will completely
decay between to cycles so you can use a single 12 pulse cycle to study those.
Similarly, long-lived isotopes will not be affected by the pulsed structure
of the cycle (the 12 pulses within it), so I'd compute the average
power of a cycle and use that for your 10 or 20 cycles.

Subject: IRRPROFILE

Hello,
I would like to increase the limit of maximum irradiation intervals which is
20 in IRRPROFIL card( As mentioned in manual).
Anyway i would also like to write some details about my requirement
I want to carry out an irradiation with a pulsed beam of 12 pulses.The time
duration of each pulse is about 2.4 microsecond and time lag(cooling time)
betweeb two pulses is about 1.2 seconds( thus making a cycle of about 14.4
seconds).This is then followed by a measurement time of about 100 seconds
and then same irradiation is done again.i want to know the resnuclei at the
end of each irradiation cycle and i want to do so for about 10 to 20 cycles
or more.Because of the limit of 20 irradiation intervals i can perfrom the
procedure for only 1 cycle.(Even that can be done only for 9 pulses)
Thank you
