Abstract: An improved dual mode scintillator detector is described that performs pulse shape discrimination of incident neutrons and gamma rays. The detector may comprise a dual mode scintillator coupled to two shaping amplifiers with different shaping times. A luminescence signal produced by the scintillator will generally produce two different signals from the shaping amplifiers, and the relative amplitudes of these signals may allow for gamma-neutron discrimination. For instance, if the scintillator produces a luminescence signal over a shorter time period for one type of incident particle (e.g., gamma events) and produces a luminescence signal over a longer time period for the other type of incident particle (e.g., neutron events), the relative amplitudes of the signals produced by each shaping amplifier can allow for gamma-neutron discrimination.

Abstract: A device that detects single optical and radiation events and that provides improved blue detection efficiency and lower dark currents than prior silicon SSPM devices. The sensing element of the devices is a photodiode that may be used to provide single photon detection through the process of generating a self-sustained avalanche. The type of diode is called a Geiger photodiode or signal photon-counting avalanche diode. A CMOS photodiode can be fabricated using a “buried” doping layer for the P-N junction, where the high doping concentration and P-N junction is deep beneath the surface, and the doping concentration at the surface of the diode may be low. The use of a buried layer with a high doping concentration compared to the near surface layer of the primary P-N junction allows for the electric field of the depletion region to extend up near the surface of the diode. With a low doping concentration through the bulk of the diode, the induced bulk defects are limited, which may reduce the dark current. The resulting structure provides a diode with improved quantum efficiency and dark current.
