One of the key components to advancing the neutron detection efficiency and increased counting efficiency, is the recent advances in high-aspect ratio deep etching techniques of a common thin-film semiconductor diode neutron detector (MSND). Neutron detector applications include those for homeland security (e.g., border screening), fundamental research (e.g., neutron scattering beamlines), and industrial monitoring (e.g., personnel monitoring, water content in soil). Solid-state neutron detectors provide an alternative to the He-3 based neutron detectors, maintaining a high thermal-neutron detection efficiency, at a fraction of the volume, mass, voltage, and power required from gas or liquid detectors.

 

MSND® Tile Technology

Solid-State Neutron Detection Applications:  The MSND® technology implements Li-6 conversion to yield a thermal neutron detection efficiency of 30%. Optimum HDPE moderator for Cf-252 neutron source at 1-m is 3-4 cm in front and 3-6 cm behind the MSND® sensor. Recommend AC coupling to electronic readout circuit.

Features:
  • Surface mount ceramic package
  • Nickel Silver RF integrated shielding
  • Thin form factor
  • Dimensions: 12.6 x 12.6 x 2.4 mm
  • 20-30% thermal neutron efficiency
  • Low power
  • Low voltage
  • Solid State
  • 1-cm^2 active area

RDT Domino® V5.4 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 efficiency, less than 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.

The Domino V5.4 Neutron Detector is calibrated to 30% thermal neutron detection efficiency, however, other desired efficiencies can be calibrated. As an advantage, a reduction in neutron detection efficiency will increase the gamma-ray rejection of the Domino Neutron Detector.

Applications

The radiation detection industry has grown over the past 50 years, due to the progression of understanding and uses of radiation in both academics and industry; with the last decade inviting concerns of improved and continued homeland security and responses to industrial accidents such as the Fukushima meltdown.  In response to this growth, RDT has developed MSND® technology that can be used for numerous applications in numerous industries.

Neutron detector applications include:

  • Homeland security & Defense (e.g. border screening)
  • Healthcare (e.g. PET/CT, SPECT/MRI instruments)
  • Fundamental research (e.g. neutron scattering beam lines)
  • Industrial monitoring (e.g. personnel monitoring, water content in soil)
  • Carbon-based & alternative energy (e.g. exploratory fossil fuel drivers)

Our neutron detectors provide an alternative to the He-3 based detectors, maintaining high thermal-neutron detection efficiency, at a fraction of the volume, mass, voltage, and power required from gas or liquid detectors.
