Filamentary Subminiature Scalers
Colin C. Harris, P. R. Bell · Review of Scientific Instruments · 1956
In order to reduce the power requirements and heat dissipation in multichannel pulse-height analyzers with parallel digital storage, we have devised and tested a low-wattage scale-of-two employing filamentary subminiature tubes. These units are designed for use in scales of 16 or 32 and exhibit great reliability and long life. The resolving time is 5 μsec with grid-catching diodes and 13 μsec unaided. For greater reliability in very long cascades and for battery operation, a Higinbotham version has been devised. Both designs promise extremely long life and may be useful wherever bistable switching circuits are used.
