“…Whether these recoiling protons are detected through cloud chamber photography, ionization, scintillation, or any other means, these techniques remain the dominant method of fast neutron detection. At the other end of the energy spectrum, detection of fission fragments from 3 He, 6 Li, 10 B and fissile isotopes present the dominant method of measuring thermal (slow) neutrons. In both cases, these detectors typically require power and data acquisition [3,4].…”

Inorganic crystal scintillators play a crucial role in particle detection for various applications in fundamental physics and applied science. The use of such materials as scintillating bolometers, which operate at temperatures as low as 10 mK and detect both heat (phonon) and scintillation signals, significantly extends detectors performance compared to the conventional scintillation counters. In particular, such low-temperature devices offer a high energy resolution in a wide energy interval thanks to a phonon signal detection, while a simultaneous registration of scintillation emitted provides an efficient particle identification tool. This feature is of great importance for a background identification and rejection. Combined with a large variety of elements of interest, which can be embedded in crystal scintillators, scintillating bolometers represent powerful particle detectors for rare-event searches (e.g., rare alpha and beta decays, double-beta decay, dark matter particles, neutrino detection). Here, we review the features and results of low-temperature scintillation detection achieved over a 30-year history of developments of scintillating bolometers and their use in rare-event search experiments.

“…The kinetic energy of the recoiling particles is absorbed by the scintillator and is converted into photons, which in turn can be detected by an extra photoelectric detector. [ 10 ] Plastic scintillators (e.g., NE102 (30.5 cm long and 12.7 cm in diameter), BC400, or EJ200), organic crystal (e.g., Anthracene), and liquid scintillators (e.g., NE213) have been commercially used as fast neutron sensitive materials. [ 11 ] Coupling with the photoelectric detector, the neutron energy and the flux information can be determined.…”

Fast neutron detection is significant for neutron imaging and flux monitoring but cannot be directly achieved by inorganic semiconductors. The traditional detection is mainly mediated by an organic scintillator and a coupled photodetector, resulting in signal losses. Here, a direct detection method for fast neutrons is demonstrated based on organic semiconducting single crystals (OSSCs) detectors. Methyl 4-hydroxybenzoate (4MHB, C 6 H 5 O-COOCH 3 ) and 4-hydroxycyanobenzene (4HCB, C 6 H 5 O-CN). The organic semiconductor acts as a fast neutron sensitive material due to its high hydrogen density, simultaneously as a semiconductor that generates the electric signal. The detectors based on 4MHB crystals can quantitatively measure the dose and energy of the fast neutron flux with a response time of 0.5 µs and detection efficiency of 78.5% cm −3 . Effects of functional groups on fast neutron detection performances are also investigated as a guideline to synthesis new molecules for this purpose. Furthermore, neutron radiation effects on these detectors are investigated. Hydrogen-related point defects are generated by fast neutrons, but device performances remain robust after irradiation of 10 13 n cm −2 fast neutrons. This study demonstrates that OSSCs show great potential as direct fast neutron detectors and particularly have highly-localized and tissue-equivalent properties that benefit neutron imaging and cancer therapy applications.
