PRELIMINALY DATA
JUN. 1999
C6438-01 is a wide bandwidth, DC to 50 MHz, amplifier. While providing the photomultiplier tube output current directly to C6438-01
input connector, it provides the voltage output signal in the conversion coefficient of 25 mV/1
A. It can be used as a wide bandwidth
amplifier not only for a photomultiplier tube but also for other detectors.
