Perforated semiconductor neutron detectors are compact, highefficiency, diode detectors that operate at low power. Microstructured neutron detector fabrication methods have been improved over 2011 IEEE Nuclear Science Symposium Conference Record N231 Arrayed High Efficiency DualIntegrated Microstructured Semiconductor Neutron Detectors The objective of this project is to design and build a highefficiency neutron detector array consisting of 3000 pixels, with each pixel being 100 microns wide and 4 cm tall, all based on the microstructured semiconductor neutron detector (MSND) technology.
Semiconductor neutron detectors Microstructured solidstate neutron detector He3 replacement technology Microstructured diode Silicon wetetching abstract Silicon diodes with large aspect ratio 3D microstructures backlled with 6LiF show a signicant increase in neutron detection efciency beyond that of conventional thinlm coated planar devices. Semiconductor diode detectors coated with neutron reactive materials have been investigated as neutron detectors for many decades, and are fashioned mostly as planar diodes coated with 10B, 6LiF, or Gd.
Perforated semiconductor neutron detectors are compact diode detectors that operate at low power and can be fashioned to have high thermal neutron detection efficiency. Fabricated from highpurity Si wafers, the perforations are etched into the diode surface with ICPRIE and backfilled with 6 LiF neutron reactive material.
Widebandgap microstructured semiconductor neutron detector technology will dramatically improve the life of neutron detectors that are placed in highfluence areas, e. g.detectors at CERNs Large Hadron Collider (LHC) are subject to fluences 1015 fast hadronscm2.

Microstructured Semiconductor Neutron Detectors (MSNDs) Douglas S. McGregor, Steven L. Bellinger, Ryan G. Fronk, Luke Henson, Taylor Ochs, J. Kenneth Shultis These dualsided microstructured semiconductor neutron detectors (DSMSNDs) have the ability to absorb and detect neutrons that stream through the frontside, effectively doubling the detection efficiency of a singlesided device.
