Perforated Semiconductor Neutron Detector Modules
Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with 6 LiF to make the pin diodes sensitive to thermal neutrons. The prototype d...
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 کاملA new active thermal neutron detector.
This communication presents the main results about the design and in-house fabrication of a new solid-state neutron detector, which produces a DC output signal proportional to the thermal neutron fluence rate. The detector has been developed within the framework of the 3-y project NESCOFI@BTF of INFN (CSN V). Due to its sensitivity, photon rejection, low cost and minimum size, this device is su...
متن کاملNine Element Si-based Pillar Structured Thermal Neutron Detector
Solid state thermal neutron detectors are desirable for replacing the current He based technology, which has some limitations arising from stability, sensitivity to microphonics and the recent shortage of He. Our approach to designing such solid state detectors is based on the combined use of high aspect ratio silicon PIN pillars surrounded by B, the neutron converter material. To date, our hig...
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...
