Abstract

The purpose of this paper is to examine new possible ways of discrimination of neutron from gamma radiation in diamond detectors. A brand new patented diamond detector was designed and tested using proton beams of various energies accelerated using the Tandem Van de Graaf and Tandetron accelerators in experimental chambers of the Laboratory for ion beam interactions of the Ruđer Bošković Institute in Zagreb. In order to corroborate that the geometry design was optimal for fast neutron and gamma ray discrimination, simulations were made using Monte-Carlo simulation tools GRAS, GEANT4 and CERN’s scientific software framework ROOT as well as SRIM.

Cilj ovog rada je ispitivanje novih mogućih načina diskriminacije neutronskog od gama zračenja u dijamantnim detektorima. Novi patentirani dijamantni detektor dizajniran je i ispitan pomoću protonskih snopova različitih energija ubrzanih korištenjem akceleratora Tandem Van de Graaf i Tandetron u eksperimentalnim komorama Laboratorija za interakcije ionskih snopova Instituta Ruđer Bošković u Zagrebu. Za potvrdu optimalnog dizajna geometrije napravljene su Monte-Carlo simulacije pomoću alata kao što su GRAS, Geant4 i ROOT za definiranje geometrije detektora, izvora i analizu, kao i SRIM programski paket.
