Description

Dear FLUKA experts,

I am a FLUKA user and I have a question regarding the correct way to count the number of positive pions (π⁺) created (produced) within a specific geometry region, not just those passing through it.

My setup:

  • FLUKA version: 4-5.0

  • Input file: Xe_W_3082MeV_0.inp(attached)

  • Geometry: I have a region named TARGET (made of tungsten) where a heavy ion beam (Xe-132) interacts.

  • I want to count the π⁺ produced exclusively inside the TARGET region.

What I have tried so far:

  1. Using USERDUMP -1.0 magdraw TARGET to write only particles created in that region, but I could not do it properly.

My specific questions are:

  1. What is the most straightforward and recommended method to obtain the total number of π⁺ produced in a specific region?

  2. If I use USERDUMP with magdraw, how can I do this? and how can I interpret the output file?

  3. Alternatively, would USRTRACK or USRBDX be more appropriate for this purpose?

I would greatly appreciate any guidance or examples you can provide.

Thank you very much for your time and help.

Best regards,

Jilberto

Hi Jilberto,

I believe you are on the right track with mgdraw, this routine indeed being the most appropriate method for your problem. You say you also tried to use the mgdraw routine already, could you also provide this file in addition to the .inp and .flair file?

If you get back to me on this I can work on answering your questions.

Best regards,

Andreas
