Dear Fluka Experts and Prof. Dr. "Alberto Fasso,

EMail:  fluka-discuss_at_fluka.org

 

Thank you very much for your response to our question regarding the thermal neutrons detection via PPAC detector.

 

Upon receiving your following suggestions:

////////////////////////////////////=//////////////////////////////////////////

As a default, charged fragments produced by thermal neutrons are not 
transported: that is why you "see" them at the gas-gap where they are 
produced, but not at the PPAC's gas gap. But for 6-Li it is possible to 
make an exception by requesting pointwise cross sections: use LOW-NEUT 
command with WHAT(6) = 1. (Leave all other WHATs = 0). 
In this way, 3-H and 4-He will be transported and will be detected far from the production point.

////////////////////////////////////-//////////////////////////////////

 

We employed them into out Fluka input file(attached), and tried. However we could not still found the 3-H and 4-He, secondaries at the gas gaps.

 

Could you please have a look into our attached files.

 

 

With best wishes, 

 Dr. M. Jamil and Kim Hyun Gee
