Dear All
I wanna calculate cosmic sources (SPE,GCR) at altitude of 35786 (GEO
orbit), so I used gcrtool folder included an example
(gcrexampleAllparticle.inp), but there are some misunderstandings.
First of all, I defined a simple input to test my source setting just for
SPE(20october2003). For this purpose, I set beam card as well as SPECSOUR
with sdum SPE2003 and a beampose card (flood) as you can see in the
attachment. In order to ensure of correct beam distribution, I defined a
vacuum sphere then I tried to get same particle distribution as source via
USRBIN and USRBDX. Unfortunately, I could not adapt output data with second
column of sep28oct2003.spc file.
Please tell me:
1) in SPECSOUR, what are Sampling index and Transition energy (as what(5)
and (6))? Should I set them?
2)I added Physics card to apply superposition model as written in the
Advanced Cosmic Rays2002.ppt, but I did not any changes with considering it
and without it.
3)Although, there are 3 columns for each H, He and O fluxes in the
sep28oct2003.spc file, I can get just proton distribution when I set it as
part in the USRBDX and there is no result when I choose Helium or oxygen ?
4) Do I define geometry and source correctly or not?
Moreover, I have Badhwar and Oneil's software to generate GCR spectra in
various Solar circumstances, How can I link them to FLUKA input file?
And, should be GCR-SPE card called to transport GCR and/or SPE with
geomagnetic field? So it is not suitable for us because I want to simulate
GCR and SPE in GEO orbit. Am I right?
What are the main shape of GCR and SPE sources?
The last but not least, when I define SPESOUR for GCR or SPE in a given
event as well as a Beam card with Proton type, dose Fluka consider other
particles like helium or heavy ions?
I appreciate you in advance.
