Characterization of a boron-loaded deuterated liquid scintillator for fast and thermal neutron detection
2021, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :However, loading a deuterated scintillator with a thermal neutron sensitive dopant, like boron, to expand the detectable neutron energy range and couple thermal capture events in the detector response function for spectrum unfolding, has yet to be explored. Since the 1970s, researchers have been exploring the benefits of deuterated organic scintillators over traditional hydrogen-based scintillators for neutron spectroscopy measurements [3,17,18]. Neutron elastic scattering on hydrogen has a symmetric forward–backward scattering angle distribution resulting in a relatively flat pulse integral spectrum for different neutron energies [2] making neutron spectrum unfolding difficult.
Deuterated stilbene (stilbene-d<inf>12</inf>): An improved detector for fast neutrons
2018, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentSolution growth of a deuterated trans-stilbene crystal for fast neutron detection
2018, Journal of Crystal GrowthCitation Excerpt :Advantages of deuteration have been demonstrated in the past with some inorganic crystals, an excellent example of which is DKDP (KD2PO4) with useful (and commercially important) properties. Among single organic crystals, growth and characterization was reported only for a relatively small (10 mm in diameter × 21 mm long), melt-grown anthracene-d10 crystal that was used for the first demonstration of spectroscopic capabilities introduced by deuterium [17]. This paper presents information on the growth of a large deuterated single crystal of trans-stilbene (C14D12, stilbene-d12).
Recent developments in deuterated scintillators for neutron measurements at low-energy accelerators
2017, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :The use of a proton converter such as paraffin to detect neutrons is still the basis for many neutron detectors many years later including organic, 1H-based liquid and plastic scintillators. Brooks et al. recognized the above features and developed deuterated-anthracene detectors and later benzene-d6 detectors(NE230,BC537) for neutron measurements [2]. However spectral unfolding techniques to obtain energy spectra were somewhat limited, although a number of useful (d,n) measurements with incident polarized deuterons were made by Lister et al. using these detectors [4].
Deuterated-xylene (xylene-d<inf>10</inf>; EJ301D): A new, improved deuterated liquid scintillator for neutron energy measurements without time-of-flight
2016, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated EquipmentCitation Excerpt :Brooks et al. originally demonstrated this effect using small deuterated-anthracene detectors [13] and later with deuterated benzene (benzene-d6, C6D6), specifically NE230 [14]. Subsequently other groups including our group at UM, have exploited deuterated-benzene detectors (BC-537, NE-230), now marketed as EJ315, in a number of nuclear reaction studies using both stable and short-lived nuclear beams, as well as demonstrating applications of such detectors in nuclear security and nuclear non-proliferation [11,15–21]. However, benzene-based liquid scintillators have potential safety issues e.g. for field applications, and in particular the low flashpoint (Table 1) and its carcinogenic properties.
