Scintillator Screens for Neutron Transmission Radiography
Neutron transmission radiography (NR) is based on the application of the universal law of attenuation of radiation passing through matter. Because different materials have different attenuation behavior the neutron beam passing through a sample can be interpreted as a signal carrying information about the composition and structure of the sample.
Generally, NR is sensitive to all materials interacting strongly with neutrons an especially to arrangements where strongly interacting materials are combined with weakly interacting materials. Unlike X-rays, neutrons interact significantly with some light materials and penetrate easily some heavy materials, making it a complementary technique to X-ray radiography.

In collaboration with the PSI (Paul-Scherrer-Institute) RC Tritec is offering scintillator screens for Neutron Imaging on the basis of ZnS mixed with 6-LiF.
Dependent on the type of ZnS used, a green or blue fluorescence is achieved. Above graph show the emission spectra of the blue and green emitting phosphors.
In joint developments with the PSI scintillator screens have been optimized to guarantee best possible light output combined with optimal spatial resolution. High luminous deposits result in higher light output where as thinner deposits show a higher spatial resolution.
Customers may choose between thicknesses of 50, 100, 200 and 300 Micrometer to fit the performance of the scintillator screen perfectly to his requirements.
Standard sizes for the screens are 200 x 200 mm or 400 x 400 mm.
RC Tritec is willing to fulfill all customers requirements. For special sizes, thicknesses or any other requests please contact us.
