Large Area Zero Bias Solid-state Neutron Detectors

Solid-state neutron detectors utilize latest advancement in semiconductors for development of efficient and economical neutron detectors. The recent shortage and price increase of He-3 resulted in more incentive to reach maturity of this technology and enable replacement of gas based neutron detectors. Solid state neutron detectors provide important advantages over current neutron detectors suc...

Towards high efficiency solid-state thermal and fast neutron detectors

Variety of applications of fast neutron detection utilize thermal neutron detectors and moderators. Examples include homeland security applications such as portal monitors and nuclear safeguards which employ passive systems for detection of fissile materials. These applications mostly rely on gas filled detectors such as 3He, BF3 or plastic scintillators and require high voltage for operation. ...

Boron carbide based solid state neutron detectors: The effects of bias and time constant on detection efficiency

Neutron detection in thick boron carbide(BC)/n-type Si heterojunction diodes shows a threefold increase in efficiency with applied bias and longer time constants. The improved efficiencies resulting from long time constants have been conclusively linked to the much longer charge collection times in the BC layer. Neutron detection signals from both the p-type BC layer and the n-type Si side of t...
