9301 Fast Preamplifier

ORTEC 9301 Fast Preamplifier
  • Used with photomultipliers, electron multipliers, etc., in photon or ion counting applications
  • 1.5-ns rise time
  • Voltage gain of 10
  • Output of ±0.7 V into 50 Ω
  • Compact and lightweight

The ORTEC Model 9301 low-noise, fast-rise-time Preamplifier has been 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, the 50-Ω input resistance of the Model 9301 provides a load resistance for the detector output current pulse.

    In addition to its fast rise time of 1.5 ns, this preamplifier has a voltage gain of 10 and an output impedance of 50 Ω. 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 cable connection to the main amplifier. Connection to a power supply is through the 3-m (10-ft) long captive power cable furnished with the Model 9301.

    Model 9301 is fitted with a power cable connector (Amphenol 17-20090) that is compatible with other ORTEC NIM-standard modules.
