CLTPCLTP Slide 34 DEPARTMENT OF SUBNUCLEAR PHYSICS The foundation of the department of subnuclear physics at IEP SAS was preceded by many years of the research at the department of nuclear physics at the P. J. afrik University. Dr. J. Patoka became the first head of the department when the IEP SAS had been established. Before 80-ies all research activities were centered mainly around the bubble chamber experiments at JINR, Dubna, Russia. At the beginning of 80-ies the main research interests shifted towards electronic experiments (e.g. HYPERON at Serpukhov, Russia). In 1980 the participation of IEP SAS at the H1 experiment at DESY, Hamburg began. The year 1984 marks the beginning of the collaboration with the CERN, Geneva, based initially on the individual contributions, but from 1991 the participation at the CERN experimental programme became official.
