Measurement of electromagnetic shower position with an electrodeless drift chamber
Abstract
Spatial resolution of a lead-glass shower detector was considerably improved by means of a converter and an electrodeless drift chamber as a coordinate detector. The coordinate of an electromagnetic shower was measured without a flash ADC; only a multi-hit TDC was used. A spatial resolution of 1.95 mm (r.m.s.) at an energy of 3 GeV was achieved. The efficiency in a relatively high shower count rate was checked.
