Microstructured semiconductor neutron detectors
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 high-purity Si wafers, the perforations are etched into the diode surface with ICP-RIE and backfilled with LiF neutron reactive material. The intrinsic thermal neutron detection efficiency depends upon many facto...
متن کاملFuture of Semiconductor Based Thermal Neutron Detectors
Thermal neutron detectors have seen only incremental improvements over the last decades. In this paper we overview the current technology of choice for thermal neutron detection – He tubes, which suffer from, moderate to poor fieldability, and low absolute efficiency. The need for improved neutron detection is evident due to this technology gap and the fact that neutrons are a highly specific i...
متن کاملDesign and performance considerations for perforated semiconductor thermal-neutron detectors
Perforated silicon structures backfilled with either B or LiF are presently under construction as high efficiency thermal-neutron detectors. Although many perforated structures are possible, there are three fundamental designs that are studied in the present work, namely (a) cylindrical perforations where holes are filled with neutron reactive material, (b) pillar configurations where semicondu...
متن کاملNeutron Detectors
Mechanisms for detecting neutrons in matter are based on indirect methods. Neutrons, as their name suggests, are neutral. Also, they do not interact directly with the electrons in matter, as gamma ray$ do. The process of neutron detection begins when neutrons, interacting with various nuclei, initiate the release of one or more charged particles. The electrical signrdsproduced by the charged pa...

Please make the following corrections on subject report. Figures 3-2 and 3-3 should be replaced by the attached figures. Page 91, line 12 should be changed to read "The Fano factor established by these measurements is .30 ± 0.03 which is entirely consistent with the approximate value of 0.32 derived from Van Roosbroeck's curves."
