April 2006AbstractThe International Linear Collider (ILC) is being designed to explore particlephysics at the TeV scale. The design of the Very Forward Region of the ILCdetector is considered in the presented work. The Beam Calorimeter - one oftwo electromagnetic calorimeters situated there - is the subject of this thesis.The Beam Calorimeter has to provide a good hermeticity for high energyelectrons, positrons and photons down to very low polar angles, serve for fastbeamdiagnosticsandshieldtheinnerpartofthedetectorfrombackscatteredbeamstrahlung remnants and synchrotron radiation.As a possible technology for the Beam Calorimeter a diamond-tungstensandwich calorimeter is considered.
