Improvement of sensitivity in avalanche-type image pickup tubes are examined. Sensitivities which are 1000 times higher than those of conventional tubes are attained by using thick amorphous Se layers (25.5μm) and by adopting a new electrode for high voltage operation. Noise characteristics of the avalanche-type image pickup tubes have been also investigated. It was found that the avalanche excess noise are extremely reduced by operational feature of the pickup tube, including the charge storage operation and the electron beam scanning.
