Doubly Irradiated “Windblown Lightning” Sculpture

This Captured Lightning® sculpture was created by irradiating a block of clear acrylic with a beam of electrons from a 5 million volt particle accelerator. An electron beam irradiated the left side, the specimen was then rotated 180 degrees, and it was irradiated once more on the opposite side. This created two independent layers of electrical charge deep inside the specimen. The rightmost charge layer was then manually discharged, creating a miniature “lightning storm” within the layer immediately above. Additional discharges then grew between the right and left charge layers, forming a beautifully interconnected 3D discharge pattern. This sculpture was then illuminated from below by blue light emitting diodes (LED’s). Unlike low-resolution laser crystal art, each of our Captured Lightning® sculptures contain a unique, and incredibly detailed, natural fractal discharge pattern. No two sculptures are identical. As they branch, the branching discharge channels become increasingly finer and hairlike, ultimately disappearing at the tips. The smallest discharges are thought to extend down to the molecular level.
