ABSTRACT:
An electron multiplier device formed of the combination of a support made of high temperature-resisting electrically-insulating ceramic material and of a layer of secondary electron emitting semi-conducting glass material fused to the inner wall of the ceramic material and method of making; the multiplier device is further characterized in that the ceramic material and the glass material have substantially the same coefficient of expansion. The device is made by pouring molten semi-conducting glass into at least one channel in a ceramic support having a higher fusion point than that of the glass and the same coefficient of expansion, flowing the glass under pressure through the channel and cooling to leave a semi-conductor wall to the channel.
