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 –2 V 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.
