Modelling and study of the Cherenkov effect

Studies at the Institute for Nuclear Research and Nuclear Energy particular ly in regard to cosmic ray detection and construction of the Muonic Cherenk ov telescope at the University of Blagoevgrad indicate a need for the devel opment of a theoretical model based on observed phenomena and a refinement of this for detection system optimisation. This was introduced in the EGS4 code system. The first simulations consecrate on a number of different geom etries of the water tank in total reflection. The model was compared with e xperimental data involving a Co-60 gamma source and the telescope. (C) 2001 Elsevier Science Ltd. All rights reserved.
