Modern 3D Lichtenberg figures or "electrical treeing" in a block of clear acrylic, created by irradiating the block with an electron beam.Actual size: 80 mm × 80 mm × 50 mm (3 in × 3 in × 2 in) Lichtenberg figures are generated by a sliding spark discharge on the flask with a mixture of gases.
Electrical treeing first occurs and propagates when a dry dielectric material is subjected to high and divergent electrical field stress over a long period of time. . Electrical treeing is observed to originate at points where impurities, gas voids, mechanical defects, or conducting projections cause excessive electrical field stress within small regions of the di
