DominoⓇ Neutron Detector

“We are happy with the Domino® due to its simplicity and low-voltage handling.  The small form factor allows for neutron generator applications like ours.”

– Brian Jurczyk, President / Starfire Industries LLC

Solid-State Neutron Detection Applications

Neutron detector applications include those for homeland security (e.g., border screening), fundamental research (e.g., at neutron scattering beamlines), and industrial monitoring (e.g., personnel monitoring, water content in soil). Solid-state neutron detectors provide an alternative to the 3He-based detectors, maintaining a high thermal-neutron detection efficiency, at a fraction of the volume, mass, voltage, and power required from gas, liquid, or crystal detectors. Recommend AC coupling to electronic readout circuit. 


MSND® Technology

The detector utilizes microstructured semiconductor neutron detector (MSND®) technology. The MSND® technology implements 6Li conversion to yield a thermal neutron detection efficiency of 30%. Optimum HDPE moderator for 252Cf neutron source at 1-m is 3-4 cm in front and 3-6 cm behind the MSND® sensor. 


The Domino® Neutron Detector

A strong demand for thin form factor neutron detectors with the flexibility to adjust available detection area has driven RDT to offer the end-to-end pluggable Domino® with 4 cm2 detection area, 30% thermal neutron detection efficiency, < 0.3 mW power consumption, and digital output per module.  The digital outputs of the Domino® may also be tied together in the tiled format.

Electronics & Interfacing: The onboard electronics package includes a preamplifier, shaping amplifier, discriminator, analog-to-digital converter, temperature sensor and voltage regulator.
