BNCT teraphy ,produced in the target new particles enegies and numbers

I want to do a bnct therapy example. Is there an example in geant4 about this? What I need is an example that shows the number and energy of new particles created in any target when I send a proton or any particle to any target.

Hello Geant4 experts
“I want to create a source of thermal neutrons for BNCT. How can I do this?”
“Can you provide an appropriate Geant4 example or guidance for achieving this goal?”
Thank you for help me
