Detection of induced pulses in proportional wire devices with resistive cathodes

Abstract If the cathode of a proportional wire device is made out of a suitably resistive material, it is possible to detect induced pulses using pick-up electrodes outside the device itself. Tests have been made on proportional tubes with helical delay lines, strips, or plates as pick-up electrodes. This method simplifies design and construction of pick-up electrodes, and furthermore allows unusual electrode arrangements.
