Hi!
Recently I was involved into design of the amplifier for photomultiplier(PMT). The problem that appears is the fact of having relatively high ambient light on top of usefull signal.
By connecting PMT directly to oscilloscope I measured 40V of DC and 1V peaks of the signal on top of that.
I want to use transimpedance amplifier to improve the bandwidth of the system, to be able to pick up gaussian pulses of 6us duration. Moreover I would like to get rid of the DC without drastic degradation of SNR.
Could you suggest me the best way to achieve my goal?
