By the use of fast neutrons dense or large materials can be analysed by Radiography and computed tomography. Motivated by James F. Hunter from Los Alamos National Laboratory, we (RC Tritec AG) evaluated in 2016 in cooperation with the Fraunhofer Institute (Germany) a production process for manufacturing large sized (450 x 450 mm) ZnS filled PP-plates for conversion of fast neutrons into...
Prototype scintillator screens were fabricated in various formats and variations, and tested with fast neutrons from a D-T neutron generator at Adelphi Technology in Redwood City, CA. The scintillators were designed with combinations of plastics+scintillator in which the hydrogen in the plastic acts as a converter for the fast neutrons producing a proton recoil reaction to yield photons within...
