Development of 12mm Proximity Focused Two-Stage Diode.

摘要

A 12 mm proximity focused double diode and a 12 mm proximity focused triple diode have been designed, fabricated, and delivered. Power supplies were designed, fabricated, and delivered. All photocathodes on the tubes were S-20 with extended red response. Both input and output faceplates were fiber optics. The 12 mm double diode output fiber optic was an inverter. A special feature of the 12 mm double diode was that it was actually two proximity focused diodes in one tube envelope. The unique design was achieved by transferring a fiber optic containing a phosphor on one side and a photocathode on the other side into the tube envelope forming the center of the double diode. A triple diode was made by placing a single diode in front of a double diode and bonding the two together. The power supplies were miniaturized and all self-contained including batteries. Photocathode sensitivities ranged from 126 microamperes/lumen to 400 microamperes/lumen. Brightness gains of up to 5000 were achieved on the double diodes and over 10000 on the triple diodes. (Author)
