Microstructured Semiconductor Neutron Detector (MSND®)
Designed by Rotunda Scientific Technologies™ LLC © 2012-2018
The MSND® technology implements Li6 conversion to yield a thermal neutron detection efficiency of 30%. Optimum HDPE moderator for Cf252 neutron source at 1-m is 3-4 cm in front and 3-6 cm behind the MSND® sensor.

• 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
Solid-State Neutron Detection Applications:
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 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. Recommend AC coupling to electronic readout circuit.
