How to use the DETECT card

I don’t understand how to use DETECT card to simulate a single energy deposition event. In manual show DETECT card means “the output of DETECT is a distribution of energy deposited per event in the region(s) making up the detector”,What is the unit of counting results?What’s the difference between “+” and “-” in reg?

Looking forward to your answer, thank you

Dear @gao_han,

a single energy deposition event most of the cases equals to the deposited energy by a single primary (and its secondary particles). You don’t need to to anything special, just run FLUKA as usual.

The explanation of the + and - signs is the following:

the DETECTOR regions of the scoring are with the + sign. Similarly, the TRIGGER regions are with the - sign.

Cheers,
David
