HI Matthew:
One possibility is the Caen quad amplifier that they made for BPMs.

I've gotten involved with a project in which stabilization of the position of
a monochromatic, soft X-ray beam is needed. The
offending frequencies seem to be vibration frequencies like 57 and 116Hz. We
have in mind to use a thin Au film with a gap in the
middle, measuring the drain current from the films, much as people normally
use the jaws of slits. Now, I'd like to find a couple
of current amplifiers which are small enough so that they can be connected
with very short cables to the BNC connectors on the
air-side of this detector, and which would have decent frequency response and
low noise with inputs of the order of 0.1-1nA.
Although this topic is outside the realm of XAFS analysis with IFEFFIT, I
figure that people on this group might have some
good experience.
