Hi folks!
I've decided to make a well known Jim William's avalanche pulse generator to test my scopes. Basically, it's a LT1073 based DC-DC converter with diode voltage multiplier and 2N2369 transistor in avalanche mode. The board itself designed to fit in a small aluminum case with a single AAA battery holder, switch and all the components. As I have never designed and routed any of hi-freq stuff before, I need help in routing ground and ground polygons.
JP1 and JP2 are external switch attachment, X1 is an BNC connector.
P.S. The board is going to be a double sided, so ground polygons are possible on both sides, the question is in shape and joint point as there are two "parts" of scheme: DC-DC converter and an output.
