A system of the present disclosure is capable of detecting, imaging and measuring both neutrons and gamma rays. The system may be portable and/or field deployable. The system may include two or more detector layer cases and a digital processing unit case. The system has a plurality of parallel plates each containing a plurality of detectors. The plates may have non-PSD organic scintillation detectors, scintillation detectors having pulse-shape discrimination (PSD) properties, and inorganic scintillation detectors. A first plate and a second plate are housed within detector layer cases. The scintillation detectors are used in connection to detect, image and measure neutrons and/or gamma rays.

Field deployable neutron/gamma spectrometer

A power supply produces one or more conditioned and scaled output voltages with low noise. The power supply has various components to produce a plurality of higher output voltages from a plurality of taps of a multiplier or multiple isolated outputs. Components include an internal reference voltage circuit or an external voltage that generates a reference voltage and a sine wave power oscillator circuit and resonant circuit that generates an alternating current and voltage. The power supply has a controlled current source circuit connected to the sine wave power oscillator circuit for regulating the power level to the sine wave power oscillator. A control amplifier circuit controls the current level to the controlled current source circuit based on the error between the sampled output and the reference voltage. The resonant transform connected to the sine wave power oscillator circuit generates one or more scaled output voltages on one or more secondary windings. A buffer voltage feedback circuit is connected to an output voltage and the control amplifier circuit for providing a feedback loop to regulate the output voltage.
