Six ground rods were driven into the ground and connected with 2 inch wide copper strap soldered to the copper clad rods. First copper cylinder series spark gap that we built, using five 2-inch diameter cylinders. Note the much larger 2.5 inch cylinder to the left. Scale pic showing just how large a 2.5-inch cylinder really is. Large cylinder gap under construction.
Cylinders sit on white fiberglass rods.
Blue Goose with 62 inch toroid. Aluminum duct toroids cannot withstand much abuse. Magnifier driver on right, extra coils on left. The flashing does not produce measurable corona. The far coil was connected with coax, but the attempt at a twin magnifier coil did not work well.
