“…Significant discrepancies are observed in the case of broad distributions which do not describe the measurements well. With a detailed modelling of the individual neutron-induced reactions on an event-by-event basis we achieved a reasonable agreement between the simulated and measured PHS which is qualitatively better than in previous works [5,6,7]. However, more reliable differential cross section data are still needed for the 3α breakup channels in 12 C. In addition, a more detailed simulation including the charge collection properties of the diamond detectors is needed in order to better understand the low energy tail of the 12 C(n,α) 9 Be peak.…”

“…Moreover, such neutron transport codes do not include the correlations between the individual reaction products with more than two particles in the exit channel, and the energy is conserved only in statistical limit. This is why in previous works [5,6,7] the MCNP simulations were enhanced by additional ion transport subroutines and response functions of a diamond detector were simulated. These works were successful in describing well the sharp peaks in the diamond detector response functions but the simulations of wide distributions still suffered from the lack of detailed modelling of the individual reactions in carbon and reliable cross section data.…”

Detectors based on single crystal synthetic diamond are well suited for high resolution spectrometry of fast neutrons. Their radiation hardness and ability to operate in extreme conditions make them suitable for neutron plasma diagnostics for the ITER project. The task of plasma diagnostics via high resolution neutron spectrometry requires a good knowledge of the response matrix of the detector within a wide energy range. In this work, the Monte Carlo particle transport code NRESP is used for the calculation of the neutron response functions of diamond detectors in the energy range 7 MeV ≤ E n ≤ 16 MeV. The NRESP code, originally developed at the PhysikalischTechnische Bundesanstalt (PTB) for the calculation of the neutron response functions of liquid scintillation detectors, was adapted for the simulation of the neutron-induced reactions which occur in a diamond detector. The simulated response functions are compared to measurements in quasi-mono-energetic neutron beams performed at the PTB ion accelerator facility (PIAF).

“…At half of the distance between the SCD and the target an aluminium disc, 1 mm thick, was positioned with the scope to shield the diamond detector from the energetic protons arising from the D( 3 He, 4 He)p reaction. This reaction occurs in tritiated targets due to the decay of tritium and the produced protons have an energy >14 MeV and can produce a strong noise signal in open window SCD.…”

“…Several nuclear reactions occur in carbon under neutron irradiation causing several types of outgoing charged particles. These reactions have been studied in several papers [1][2][3][4][5][6]. Neutron-carbon interactions release the energy of the reaction products in the diamond detector and produce an output signal proportional to the deposited energy.…”

Abstract. Measurements of C12 cross sections for the excited states (n,p 0 ) up to (n,p 4 ) and (n,d 0 ), (n,d 1 ) have been carried out. The Van de Graaff neutron generator of the EC-JRC-IRMM laboratory has been used for these measurements. A very thin tritiated target (263 µg/cm 2 ) was employed with deuteron beams energies impinging on the target in the range 2.5-4.0 MeV. Neutrons in the range 18.9-20.7 MeV were produced with an intrinsic energy spread of 0.2-0.25% FWHM. With such narrow neutron energy spread, using a high energy resolution device such as a single crystal diamond detector, several peaks from the outgoing charged particles produced by the (n,p n ), (n,d n ) and also (n,α 0 ) reactions appear in the pulse height spectrum. The peaks can be identified using the reaction Q-values. The diamond detector used for these measurements has shown an intrinsic energy resolution lower than 0.9% FWHM. The analysis of the peaks has permitted to derive the partial carbon reaction cross sections for several excited states. The results are presented in this paper with the associated uncertainties and they are compared with different versions of TENDL compilation when these data are available (e.g. versions
