I am trying to simulate Gd2O3 scintillator for neutron. When I add Raddecay card “error code 12 occurs”. if I remove Raddecay and associated cards, other card outputs work properly. I could not understand the reason for it.
And, when Gd capture neutrons, it emits electron, photon x-ray and gamma ray. I used “ray” function in USEBIN, USERTRACK, etc… But it seems bit odd to me. is there any other function that can use for X-ray?
Here is the full spectrum of DETECT card, how do I add the ACCUMN or ACCUMP to it on flair?
I am grateful, if anyone can help me with this questions. Gd2O3Eu_09April21.flair (5.9 KB)
In the simulation you are missing the PHYSICS card with SDUM=EVAPORAT which activates heavy fragment evaporation. This is needed for residual nuclei production and decays. This will solve the error you are getting.
Also include an additional EMFCUT card to define the PROD-CUT for photons and electrons.
Carefull with the option “RAY”, it is a pseudo-particle used in FLUKA, for instance, to scan the geometry.
It does not refer to X-rays. Both, X-rays and gamma rays are scored using the PHOTONS option.
Regarding the spectrum obtained by the DETECT card and your comment “How do I add the ACCUMN or ACCUMP to it on flair?” Could please be more precise about what you want to do?
Many Thanks for the reply and advices.
In attached figure, peaks can be observed in spectrum, but i would like to convolute the recorded spectrum with the Gaussian function. For that, I am trying to include ACCUMP and ACCUMN. is there any other method to do it?
no, only one “dummy” DETECT card is needed for the user routine to work. The energy settings and scoring regions on the “dummy” card also do not matter. The only requirement is that the “dummy” card has to be the last among the DETECT cards.
