Surface discharges on a wood block II
Another wood block discharge photo with a different wood block and electrode configuration. The wood block was placed on top of the negatively charged VDG terminal and a grounded cookie sheet was placed above the wood block. These discharges have more energy than the previous setup. The photo is rotated 90 degrees. Towards the top of the photo, a red/orange subsurface discharge is seen to emerge from the wood surface and then go back down below surface again.
