“…The energy resolution measured at 662 keV is 7.2 ± 0.1% (FWHM). This is a better value than achieved in previous work [8], but not as good as expected. The low energy threshold is ~10 keV using our simple level trigger.…”

“…In our previous work we required a coincidence between fast outputs in order to reduce the effects of uncorrelated dark counts and lower the trigger threshold [8]. Due to the improved light collection of the larger S10985, however, we did not find this to be necessary this time.…”

“…Initial testing of the S10985 was conducted using a 0.5″ × 0.5″ cylindrical LaBr 3 detector ( Fig. 1) purchased from SaintGobain Crystals and used in our previous SiPM work [8]. After confirming basic operation, the device was sent to SaintGobain for integration into a hermetically sealed detector package.…”

New scintillator materials have been shown to hold great potential for low-cost, reliable gamma-ray detectors in high-energy astronomy and solar physics. Commercially available silicon photo-multipliers (SiPMs) promise to make scintillator-based instruments even more attractive by reducing mass and power requirements. SiPMs have by now been shown to perform well as readouts for scintillator gamma-ray detectors in the laboratory. We present results from ongoing work to investigate whether SiPMs are appropriate for use in space, including the Monte Carlo modeling of the light collection in a small LaBr 3 /SiPM spectrometer scheduled to fly on a highaltitude balloon flight in 2011.

New scintillator materials have been shown to hold great potential for low-cost, reliable gamma-ray detectors in high-energy astronomy and solar physics. New devices for the detection of scintillation light promise to make scintillator-based instruments even more attractive by reducing mass and power requirements. In particular, silicon photomultipliers (SiPMs) are commercially available that offer gains and quantum efficiencies similar to those of photomultiplier tubes (PMTs), but with greatly reduced mass, high ruggedness, low voltage requirements, and no sensitivity to magnetic fields. SiPMs have by now been shown to perform well as readouts for scintillator gamma-ray detectors in the laboratory. Before they may used in space-based instruments, however, it must be shown that 1) sufficiently large light collecting areas may be fabricated without loss of performance;2) the variability of the gain with temperature can be compensated for; and 3) that SiPMs are sufficiently robust and radiation hard. We present results from ongoing work to investigate whether SiPMs are appropriate for use in space, including data from the successful flight of a combined LaBr3/SiPM detector on a high-altitude scientific balloon, and the performance of larger gamma-ray spectrometers with improved light collection.

Dose spectra from energetic particles and neutrons

et al. 2013

[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.
