The front end preamp is designed for use in demanding low noise, high speed, and high background applications.
Consisting of a gated boxcar integrator, an independent reset function, and other proprietary functionality not shown in the figure, the front end is dynamically controlled and reconfigured to support any one of several advanced triggering and data acquisition modes.
When coupled to a typical multi-anode PMT, this deceptively simple circuit achieves single photon sensitivity at microsecond-level pulse-pair resolution.
