“…The high-speed version for monophoton technique was adopted by Kirkbride et al [9]. Simple and equally precise way of measuring the decay time has been elucidated [10]. Trans-stilbene crystals have been grown by selective selfseeding vertical Bridgman Technique (SSVBT) and conventional vertical Bridgman technique reported by the authors [11].…”

“…The decay time constants of the HPS crystal were 5.4, and 21 ns, which were shorter than those of anthracene, trans-stilbene, and DPA and longer than those of p-terphenyl crystals. 2,5,6,46 Conclusions HPS crystals were synthesized to develop scintillators based on AIE behavior. HPS crystals showed an emission peak at approximately 490 nm in the PL emission and XRL spectra and scintillation decay time constants of 5.4, and 21 ns, which are shorter than those of conventional organic crystal scintillators.…”

“…Recoil protons from elastic neutron scatters excite atoms in the scintillator via ionization, which in turn produces optical scintillation photons that are detected by the SiPMs. Neutron interactions may be distinguished from gamma ray interactions (recoil electrons from Compton scatters) via PSD: In many organic scintillators, including stilbene, the decay time of the scintillation light depends on the energy loss (d E /d x ) of the ionizing particle [e.g., Harihar et al ., ]. The time required for the detector's electronic pulse to decay a given amount (e.g., from its peak to ~20% of peak) is one measure of this decay time and permits proton signals to be identified.…”

Dose spectra from energetic particles and neutrons

[1] Dose spectra from energetic particles and neutrons (DoSEN) are an early-stage space technology research project that combines two advanced complementary radiation detection concepts with fundamental advantages over traditional dosimetry. DoSEN measures not only the energy but also the charge distribution (including neutrons) of energetic particles that affect human (and robotic) health in a way not presently possible with current dosimeters. For heavy ions and protons, DoSEN provides a direct measurement of the lineal energy transfer (LET) spectra behind shielding material. For LET measurements, DoSEN contains stacks of thin-thick Si detectors similar in design to those used for the Cosmic Ray Telescope for the Effects of Radiation. With LET spectra, we can now directly break down the observed spectrum of radiation into its constituent heavy-ion components and through biologically based quality factors that provide not only doses and dose rates but also dose equivalents, associated rates, and even organ doses. DoSEN also measures neutrons from 10 to 100 MeV, which requires enough sensitive mass to fully absorb recoil particles that the neutrons produce. DoSEN develops the new concept of combining these independent measurements and using the coincidence of LET measurements and neutron detection to significantly reduce backgrounds in each measurement. The background suppression through the use of coincidence allows for significant reductions in size, mass, and power needed to provide measurements of dose, neutron dose, dose equivalents, LET spectra, and organ doses. Thus, we introduce the DoSEN concept: a promising low-mass instrument that detects the full spectrum of energetic particles, heavy ions, and neutrons to determine biological impact of radiation in space.
