USE OF TWO-PHOTON ABSORPTION IN INORGANIC SCINTILLATOR MATERIALS FOR FORMING SUB-PICOSECOND TIME STAMPS OF INTERACTION WITH IONIZING RADIATION
Abstract
The features of the two-photon absorption signal in lead tungstate crystals (PbWO4) in the “pump – probe” experiment are considered. The differences in the spectral dependences of the recorded two-photon absorption effect in the presence of ionizing radiation of a crystal and without it are discovered. The method of utilizing the effect to generate a time stamp of interaction of ionizing radiation with a scintillator is proposed.
