Say what -- arcing TO polycarbonate!
« on: August 11, 2022, 10:56:28 PM »
I put a resistor string in a polycarbonate (or may be acrylic) tube filled with mineral oil.  The bottom of the tube structure is 1/4" polycarbonate, which is sitting an a piece of 1/4" thick micarta, on a plastic roll around cart.

The resistor string totals 1G and it's across the output of a CW multiplier that's making 25" sparks.

Low and behold, there are small (<1") arcs through the oil into the polycarbonate bottom  What in the world is going on?  What could be attracting the arc?
