Hi,
i made several cloud chambers which work really well. A Spark chamber was always on my to do list, but i had no time up to now to build it.
An a lot simpler design was made by Carl Willis:
I think for the first try something like this is a lot easier to set up.

These are called a Frisch-grid and are comanly used to detect ionising radiation they also have the capability to give the direction of the incoming particle / photon.
Usually use an organic gas such as propane and argon at partial pressure with a thin window into the detctor area (windows from kapton polyehtylene or whatever
commonly used in accelerator mass spectrometry and particle physics laboratories like ours
