General
The Model 9306 1 GHz Preamplifier is optimized for fast timing and counting applications with detectors that deliver pulses with ultra-fast rise times. An output rise time of 350 ps and a non-inverting voltage gain of x100 make the Model 9306 ideal for use with microchannel plates, microchannel-plate photomultipliers, channeltrons, silicon diodes, fast photomultiplier tubes, and electron multipliers. It is particularly suited to use with the Model 9307-P pico-TIMING Discriminator to give optimum time resolution with ultra-fast detectors. Its compact case allows close coupling to the detector to minimize sensitivity to environmental noise.
To preserve the ultra-fast rise time, the Model 9306 is designed to accept and deliver signals on high-quality, 50 W coaxial cables with SMA connectors and 50 W terminations. The input is AC coupled, with a 50 W input impedance, and is protected to a maximum of ±1 V. Two identical outputs are provided for convenient, simultaneous connection to two different instruments. Both outputs are AC coupled, short-circuit protected, and capable of driving pulse amplitudes from 0 to -2V into 50 W loads.
The preamplifier is designed for use with 50 W coaxial signal cables having SMA connectors. To avoid degradation of the 350 ps rise time through long signal cables, the total length of the input and output signal cables should not exceed 1.7 m (5'). 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 and power supplies.
All specifications below were measured with a pulser having a pulse width of 2 ns FWHM, and a rise time of 150 ps. Where significant, the measurement is corrected for the rise times of the pulser, coaxial cable, and oscilloscope. The specifications are identical for both outputs 1 and 2.
