2.4.1 Electrometer-Amplifier
The collector cable is coupled directly to a coaxial fitting located on
the electrometer-amplifier PC board. The PC board is located on the side
panel next to but outside of the isothermal chamber. It consists of an
electrometer amplifier and an operational amplifier. This circuit is a very
high-gain, current-to-voltage converter circuit, having an input
impedance measuring in the billions of ohms. It is static sensitive and
highly susceptible to contamination. Special care must be taken in
handling this PC board.
Refer to Section 5.5.3: Electrometer-Amplifier PC Board for more
information concerning the electrometer-amplifier and the other printed
circuits that follow.
