Image Intensifiers
For wavelengths larger than VUV (i.e., near UV, visible and IR) sealed detector tubes, so-called image intensifiers, can be used. Usually such image intensifiers are read out using an optical screen and the time information is lost. RoentDek can supply electronically coupled delay-line or wedge-and-strip readout systems for special image intensifiers that presume the timing information for each photon. These image intensifiers with high resistive screen for (electronic) coupling with special RoentDek anodes are produced by Exosens Imaging Germany GmbH.
Such detectors could also be used for position and time resolved high energy X-ray detection if such a special image intensifier is combined with a scintillator window (see the website of Photek Ltd).
Currently we investigate the possibility to detect thermal and high energetic neutrons with neutron sensitive scintillators coupled to the image intensifier for time- and position-sensitive image readout with RoentDek anodes.
