A Multiplier for Use with E-DE/DX Particle Identifiers

The Vela 5 satellite energetic particle experiment will employ an E-dE/dX particle identifier in which the 2-pulse multiplication is performed by a gated, constant current circuit. The multiplication time is proportional to pulse height and varies betwieen 1.5 and 15 microseconds. The multiplier output is a reasonably accurate representation of the product of the input pulses, and is nearly independent of temperature.
