Scintillators and Wavelength Shifters for the Detection of Ionizing Radiation

New scintillators and waveshifter materials are under development for use in detecting charged particles in tracking applications and for detecting showering particles in calorimetric applications. Goals have been to identify and produce fast and efficient dye materials that fluoresce in the middle of the visible spectrum where polystyrene and polyvinyl toluene have good optical transparency, to replace existing materials currently in use in the field of particle physics. As a result of this study, several fluorescent dyes have been identified with fast and efficient emission, that fluorescence in the green (lambda similar to 490-520 nm). These are candidate materials for new scintillators and waveshifters.
