Hi, folks!
I'm currently designing my own version of PCB for this avalanche pulse generator. This board will be placed in aluminum box. BNC connector is a PCB vertical thought hole connector that will be soldered to the board parallel. The 50 ohm resistor mounted vertically right under signal/central wire. This is me very first design of such type generators (and frequency), so I want to know what do you think about ground polygon distribution. I separated grounds of voltage source and the output part. Any ideas how to improve?
Oh, and there is a switch on the right side of the box.
