“…As a wide band gap semiconductor with properties such as low dark current, fast response time, high carrier mobility, good radiation resistance, and bio-compatibility, diamond has drawn much attention recently in the field of ionization radiation detection [1][2][3] for UV, 4 gamma-ray, 5 X-ray, 6,7 neutrons, [8][9][10] protons 11 and heavy ions, 12 especially in Large Hadron Collider accelerator. Diamond detector shows advantages in low dark current and good radiation resistance.…”

Polycrystalline CVD diamond detector: Fast response and high sensitivity with large area

Polycrystalline diamond was successfully used to fabricate a large area (diameter up to 46 mm) radiation detector. It was proven that the developed detector shows a fast pulsed response time and a high sensitivity, therefore its rise time is lower than 5 ns, which is two times faster than that of a Si-PIN detector of the same size. And because of the large sensitive area, this detector shows good dominance in fast pulsed and low density radiation detection.

“…This high quantity of neutrons with energy in the range of 1 eV-100 keV gives hope for successful thermal neutron imaging using LiF detectors due to the higher efficiency of their absorption compared with MeV neutrons. It is also necessary to mention that, recently, LiF films embedded with Li 6 have been successfully used as converters of neutrons in tokomak experiments with thermonuclear neutrons [41,42] . The subsequent results give confidence that LiF detectors could be successfully used for high-resolution imaging of plasma neutron sources.…”

This paper describes an overview of our recent discovery -clear demonstration that LiF crystals can be efficiently used as a high-performance neutron imaging detector based on optically stimulated luminescence of color centers generated by neutron irradiation. It is shown that the neutron images we have obtained are almost free from granular noise, have a spatial resolution of ∼5.4 µm and a linear response with a dynamic range of at least 10 3 . The high contrast and good sensitivity of LiF crystals allow us to distinguish two holes with less than 2% transmittance difference. We propose to use such detectors in areas where high spatial resolution with high image gradation resolution is needed, including diagnostics of different plasma sources such as laser and z-pinch produced plasmas.

“…Figure 3). It must be pointed out that also the incoming neutron beam was simulated with a Monte Carlo code; the latter takes into account the p(T, 3 He)n and p( 7 Li, 7 Be)n reaction cross section, the proton energy loss in the targets, and the geometrical parameters of the experimental setup.…”

“…1- 3 Recently it has been shown that SDs can play a role as compact neutron spectrometers in high neutron flux environments and where there is limited space, e.g., neutron cameras. 4,5 Neutron detection in SD is based on the collection of electron-hole pairs produced by charged particles generated by neutron interaction with 12 C nuclei.…”

Single crystal diamond detector measurements of deuterium-deuterium and deuterium-tritium neutrons in Joint European Torus fusion plasmas Rev. Sci. Instrum. 85, 043506 (2014) A Single-crystal Diamond (SD) detector prototype was installed at Joint European Torus (JET) in 2013 and the achieved results have shown its spectroscopic capability of measuring 2.5 MeV neutrons from deuterium plasmas. This paper presents measurements of the SD response function to monoenergetic neutrons, which is a key point for the development of a neutron spectrometer based on SDs and compares them with Monte Carlo simulations. The analysis procedure allows for a good reconstruction of the experimental results. The good pulse height energy resolution (equivalent FWHM of 80 keV at 2.5 MeV), gain stability, insensitivity to magnetic field, and compact size make SDs attractive as compact neutron spectrometers of high flux deuterium plasmas, such as for instance those needed for the ITER neutron camera.
