Plot spectre of X-ray energy

Dear fluka experts, I plot my data, but I don’t find the specter that I expect can you help, please
Best regards
this is the specter i get


and this is what i want to get

Dear @kitaniabdellah,

I think that you are interested in using USRTRACK for scoring the photons.

Dear @kitaniabdellah ,

I think quite possible is that the number of primaries used in the simulation is too small so that there is not enough statistics in the result. Maybe increase the number of primaries to the order of 1E7 or more, the ‘wanted’ result can be exhibited. Also the energy cut-off may be too small so that the time for the simulation can be quite long, maybe first take several keV to take a try and then decrese accordingly is a better way.

Best,
Xiao

dear @Mihaela_Parvu
can you explain more please
Best regards

Dear @yuxiao i will try 1e+07 , i hope it’s working
thank you

Dear @yuxiao thank you so much for your advice
best regards

Later edit

Dear @kitaniabdellah,

If you want to score only the X-ray spectrum you have to use USRTRACK, since the DETECT card scores all the particles. Take a look here Question about DETECT - #3 by dprelipc

hello fluka experts i want to plot this specter of x-ray energy but i can’t get the right specter

thank you for your advices

As I mentioned in an earlier post, you cannot obtain only the X-rays spectrum by using the DETECT card, but by using USRTRACK with the scoring of photons. I see that you introduced this card, but the particles that you are scoring are electrons.

Please look at the attached file.
