The primary detection system is configured to acquire initial data of an object being analyzed. The secondary detection system includes at least one neutron source and at least one detector. The at least one detector is configured to acquire spectral emission data from the object generated responsive to neutrons provided by the at least one neutron source. The at least one processor is configured to acquire, from the primary detections system, the initial data from the object; determine a sub-portion of the object for further analysis using the initial data; direct at least one neutron beam from the at least one neutron source toward the sub-portion; acquire, from the secondary detector system, the spectral emission data from the object; and determine a presence of a substance using the spectral emission data.

Abstract: A photon detector having an optical transparent plate and photodiode array interconnected by an optical light guide array. The optical light guide array including elements providing a transmission line between the optical transparent plate and the photodiode array, where the position of one or more optical light guide elements is formed to adjust for a miss-registered photodiode individual element. A method for assembling the photon detector includes depositing a non-wetting film on opposing surfaces of the optical transparent plate and/or photodiode array, altering the deposited non-wetting film in regions of individual photodiode elements, dispensing an optical coupler adhesive on the optical transparent plate and photodiode array to form adhesive beads, aligning the opposing surfaces, assembling the opposing surfaces so that the corresponding optical coupler adhesive beads contact each other, and curing the optical coupler adhesive to form a structurally merged photon detector having optical light guide elements.

Abstract: A silicon photomultiplier (SiPM) based detection system includes a plurality of scintillators, SiPMs, a front end circuit, adjustment circuits, and an energy and position processing unit. The SiPMs have a non-linear response to energy deposition corresponding to radiation detection. The adjustment circuit is configured to receive an analog signal from SiPMs, and to provide an adjusted analog signal, which is configured to simulate a signal corresponding to a linear response. The energy and position processing unit utilizes the adjusted signal to provide energy and position information of detected events in the detector block.
