Forward calorimetry for TeV-colliders

A version of the compressed gas ionization calorimeter is presented based on stacks of stainless steel tubes. The volume between the tubes is filled with molded lead plates as passive material (including the tube walls). The active material is gas Ar+10%CH4, P=100 atm. Our Monte Carlo simulation was performed with the GEANT program, where the statistical term coefficient and constant term of the calorimeter energy resolution for protons and electrons are presented versus to the geometrical calorimeter parameters (inner tube diameter, volume ratio of passive to active materials, and angle). 6 refs.; 10 figs
