產品說明
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 or liquid detectors.
The RDT Domino®
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, 20% to 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.
MSND® Technology
The detector utilizes microstructured semiconductor neutron detector (MSND®) technology? with 6Li conversion to yield an adjustable thermal-neutron detection efficiency of up to 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.
Electronics & Interfacing
The onboard electronics package includes a preamplifier, shaping-amplifier, discriminator, analog-to-digital converter, temperature sensor, and voltage regulator.
