Fast Low-Power-Drain Logic System for Use in Nuclear Experiments on Scientific Satellites

A fast low-power-drain logic system has been developed for use in nuclear experiments on scientific satellites. The system consists of a compatible set of AND and NAND gates, pulse generators, delays and bistables. Each basic circuit unit has a response time in the 10 nanosecond range and power drain in the 2.0 milliwatt range. The basic units may be directly interconnected to form a required logic system. The basic circuit units, their use in a typical coincidence anti-coincidence system and their possible use in event priority and wide dynamic range pulse height analyzer systems is described.
