Study of cascade showers generated by near-horizontal muons in the water Cherenkov detector with a dense array of optical modules

摘要

The method for reconstructing the cascade curve by the Cherenkov radiation in water of the NEVOD detector with a dense spatial array of optical modules is discussed. Cascades are generated by near-horizontal muons which are separated by the DECOR coordinate detector. The cascade curves and the cascade energy spectrum measured in an similar to 8000-hour measurement series are presented.
