General
The Model 9301 low-noise, fast-rise-time preamplifier is designed for use with photomultipliers, electron multipliers, and other detectors employed in photon counting, ion counting, or fast-timing applications. When connected to the detector, its 50 W input impedance provides a suitable termination for the detector output current pulse.

In addition to its fast rise time of 1.5 ns, this preamplifier has a voltage gain of x10 and an output impedance of 50 W. Because of its compact size and light weight, the Model 9301 is ideal for mounting directly or close to a detector. Consequently, low-level signals, which would otherwise be susceptible to pickup of noise or interference, are boosted to a suitable level for connection to the following instrument.

The instrument is powered via an integral 3 m (10') long power cable fitted with a 9-pin D type connector that is compatible with ORTEC NIM-standard modules.
