A detector for neutron imaging
2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2003A bright neutron source such as the Spallation Neutron Source (SNS) places extreme requirements on detectors including excellent 2-D spatial imaging and high dynamic range. Present imaging detectors have either shown position resolutions that are less than acceptable or they exhibit excessive paralyzing dead times due to the brightness of the source ...

Journal of Neutron Research, 1996
The principles involved in gas detectors for neutrons and the techniques for position encoding in such detectors are reviewed. This forms the basis for a discussion of the limitations on gas detector position resolution and maximum data rates, and of the aging effects in such detectors. Current capabilities and possible areas for improvement are noted.

Semiconductor neutron detectors
SPIE Proceedings, 2016Lithium Indium Selenide (LiInSe2) has been under development in RMD Inc. and Fisk University for room temperature thermal neutron detection due to a number of promising properties. The recent advances of the crystal growth, material processing, and detector fabrication technologies allowed us to fabricate large detectors with 100 mm2 active area.

IEEE Transactions on Nuclear Science, 1969
A miniature neutron detector has been designed to verify the correct operation of a pulsed 14-MeV neutron generator. The detector consists essentially of the following components: a plastic scintillator which converts neutron energy to light; a photomultiplier tube which collects light and converts it into an amplified electrical signal; a power supply

Nuclear Instruments and Methods, 1973
Abstract A fast time-response detector for absolute neutron flux measurements was designed. The detector consists of a medium size liquid scintillator tank with an entrance channel for a collimated neutron beam. The primary neutron energy is transformed by successive collisions into proton and carbon recoils resulting in a light flash which is ...
