“…The p-Terphenyl single crystal scintillator allows a better discrimination, indeed, but the available size is still limited. New plastic scintillators offer a promising alternative [6]. The accuracy of the discrimination depends much on the correct determination of the base line and the start moment of the signal.…”

“…Different kind of the scintillator are used in various types of detectors. Organic plastic and liquid scintillators are used to detect high-energy neutrons in the presence of gamma radiation background [3,4]. The inorganic crystal scintillators are ideal for detection of X-and γ-ray, their higher density and atomic number Z cause better detection efficiency.…”

From various types of scintillating materials lutetium-yttrium oxyorthosilicate (LYSO) has the highest luminosity and the greatest potential of application in high-energy radiation detectors. Due to the small critical angle of total internal reflection the enhancement of the extraction of light outside a scintillator is a challenge. We study numerically the influence of the effective refractive index layer on the transmittance of LYSO crystal. It is possible to realize such layer by sub-wavelength patterning of crystal surface using for example focused ion beam. The enhancement of transmittance of LYSO crystal up to 100% as well as the possibility to tune the positions of transmittance maxima have been shown.

“…The invention of solid ("plastic") scintillators 4,5 which exhibit PSD capability, such as the EJ299-33 scintillator used in the present work, remove the toxic and fire hazards associated with most liquid scintillators. Furthermore, plastic scintillators have no need for an optical window when coupled to a photodetector and may be easily produced in any geometrical form.…”

Progress towards the realization of a new compact neutron spectrometer is described. The detector is based on EJ299-33 plastic scintillator coupled to silicon photomultipliers, and a digital implementation of pulse shape discrimination is used to separate events associated with neutrons from those associated with gamma rays. The spectrometer will be suitable over the neutron energy range 1-100 MeV, illustrated in this work with measurements made using an AmBe radioisotopic source and quasi-monoenergetic neutron beams produced using a cyclotron.
