“…The variance reduction method presented in ref. [18] is applied to calculate the number of neutrons produced from the D-D cross section for each track in the target. Eventually, the total PNG neutron production rate is estimated, and the position, momentum direction, and energy of the produced neutrons are calculated/recorded by the Geant4 toolkit.…”

“…However, there are some extensions to the Monte Carlo codes such as the MCUNED [15], the ENEA-JSI [16], the SRIANG [17], and the DDT to simulate the D-D/D-T reaction. Very recently, the possibility of simulating the D-T reaction in the GEANT4 toolkit has been evaluated by implementing a variance reduction technique [18]. The most advantage offered by the GEANT4 over other codes/extensions, is the ability to track the deuterons inside an electromagnetic field.…”

Pyroelectric crystals are heated/cooled to supply D-D/D-T fusion for the purpose of neutron generation. Enhancing the pyroelectric neutron generators (PNG) yield is one of the main goals pursued by most of the previously developed techniques/models. Here, the maximum possible neutron yield of a PNG is calculated in which a widely-used pyroelectric crystal (i.e., LiTaO3 with a diameter of 3 cm and height of 1 cm) is applied. This calculation is performed by a simulation procedure including: (1) computation of the PNG potential/current for neutron generation based on new modifications (2) simulation of the deuterium ions acceleration into the target during a thermal cycle (3) simulation of the D-D fusion interaction using the Geant4 toolkit. The results show that the maximum yield of the PNG in the ideal conditions is about 6.4× 106 neutrons per cycle. This study provides a useful approach for determining the upper limit of the expected efficiency for typical PNGs and other compact neutron generators.

“…There are many codes can be used for modelling the production of fusion neutrons such as the MCUNED, the NEUSDESC, the PROFIL, the TARGET, the SHORIN, the SRIANG, the ENEA-JSI, the DDT and recently the Geant4 toolkit [10][11][12][13][14][15][16][17][18][19][20]. The detailed description of these codes is in [10,11]. Here, the advantages and the disadvantages of the codes are given.…”

A mixture of deuterium (D) and tritium (T) is the most likely fuel for fusion reactors and hence the D(d,n)3He and T(d,n)4He fusion reactions are the ones that will fire fusion reactors in the future. Both of the fusion reactions produce neutrons which escape form the reactor core and can be measured directly outside the core. As the neutrons have large mean free path and neutral charge, they readily carry information about the burning fusion plasma from inside to outside the reactor core without being affected by electric or magnetic fields. From the produced neutrons of the D(d,n)3He and T(d,n)4He fusion reactions, the neutron yield of each reaction and the neutron yield ratio of the two reactions are calculated. This ratio is of critical importance for controlling the fusion fuel burning which is a high priority issue for fusion reactor performance. Because it is very difficult to measure this ratio experimentally, accurate theoretical calculations of the neutron yield ratio besides the related deuterium and tritium energy spectra in the fusion plasma are needed. In the present work, neutron yields of the D(d,n)3He and T(d,n)4He fusion reactions have been calculated using the MCUNED, the ENEA-JSI, the DDT codes and the Geant4 toolkit. The related deuterium and tritium energy spectra have been calculated by the MCUNED code. The relation between the ion temperature and the neutron yield in the imploded fusion plasma is discussed. Calculations are compared to the available experimental data. Comparing to the other codes, the spectrum of the fusion neutrons simulated by the MCUNED is the only one that fit the experimental data.
