Evaluation of LGSO:Ce scintillator for high energy physics experiments

The work is focused on the development of production methods of large scintillators based on lutetium-gadolinium oxyorthosilicate doped with cerium Lu2xGd2−2xSiO5:Ce (LGSO:Ce). Large LGSO:Ce crystals were grown by the Czochralski method, and a set of experimental samples for testing of scintillation characteristics was produced. Possibilities are discussed to use this scintillator in high energy physics experiments. In particular, an electromagnetic calorimeter to search for conversion of electrons into muons, which is forbidden in the Standard Model.
