Nowadays the measurements of time of registration in colliding beam experiments improves. LYSO(Ce) crystals could be used as fast counter of particle's arrival time with accuracy better than 100 ps. There is the investigation of Cherenkov radiation influence on time of registration and its accuracy in LYSO(Ce). The result contains the data from the test beam experiment.
