Let's say I want to measure the speed of light using a LED pulser and a photomultiplier tube.
A quick web search doesnt turn up anything relevant.
I suppose I need an avalanche driver into a fast LED.
And a fast amplifier on the photomultiplier tube.
And a good sampling head on the 7S11 plugin. Or I'll have to fix the bad power supply on the 7104.
Now I could guess some ballpark numbers, like a few hundred pF discharging through a fast transistor. And maybe a MMIC stage or three to amplify the phototube current.
But of course itprobably takes plenty of optimizing all the little details to get the best risetimes.
Anybody been there, done that, and have any proven circuits?
Thanks,.
