Dear Fluka experts and users,
I have just recently installed Fluka, and am a complete beginner. I aim to calculate inelastic cross sections in heavy ion collisions such as carbon beam, incident on a graphite target block at momentum beyond 10A GeV/c. Is there an example input file or is there a simple way to understand to create an input file for such interactions, outputting cross-sections in mb?
Best,
Neeraj
Dear @neamin ,
I’m happy to recommend you the FLUKA beginner’s course which will take place at CERN beginning of December, the registrations should be open until October 13th and it’s the ideal place for someone new to FLUKA to receive an excellent basic training. If you are unable to attend, I would advise you to take a look at the course material of previous FLUKA beginner’s courses, you can find those in the timetable of the indico page. In particular, the “Scoring I & II” and “Hadron Physics” items of the basic course will be of interest for you.
Once you get acquainted with the basics you can continue to your heavy ion problem. There is a heavy ion input template in Flair to get you started. The topic of calculating cross sections using FLUKA is quite involved, there is a lot of information available on this forum. You can start for example with this post on scoring cross section values using USRYIELD or this post about the units of the USRYIELD output. In addition, there are this post about calculating cross sections with a thin target and this or this post that give a bit more details on the output and comparison to experimental data.
Don’t hesitate to ask for further questions in case you run into trouble!
Cheers,
Andreas
