Abstract
We report on the design and construction of the cathode image readout secti on of the BELLE detector's central drift chamber. The cathode information i s used for measurements of charged particle trajectory coordinates along th e beam axis and the charged-track trigger. The performance is evaluated wit h cosmic rays using the BELLE standard readout electronics and software. Th e detection efficiency in nominal conditions is found to exceed 98% and the position resolution for normal incidence is about 350 mum, which satisfies the design goals of the BELLE detector.
