A charge division method for the determination of the γ-conversion point in a liquid krypton calorimeter

Abstract Calculations of the spatial resolution of a liquid krypton calorimeter are presented. The calorimeter consists of towers of 10×10 cm 2 with a 1 cm anode cathode gap. The anodes are strips with Δ = 10 or 5 mm wide. The coordinate is determined on the conversion point with an accuracy σ tot 2 = Δ 2 12 + σ X 2 , where σ X is the noise error. The conversion point, in its turn, is determined by the charge division in the capacitance line. This line is has a strip cathode capacitance C 2 and an outer interstrip capacitance C 1 . The condition σ X ⪡ Δ √12 is shown to be always fulfilled by an appropriate choice of C 1 C 2 and the filter time τ. The results may be used for particle detectors of other types.
