| Overview: A GoPro Hero 3+ silver camera was shielded with lead and sent through an industrial irradiator while viewing plastic and mineral samples. The plastics were used to produce lichtenberg figures. The irradiation facility is the Mercury Plastics NeoBeam facility which is used for cross linking plastics. The accelerator can produce a 5MeV, 20mA electron beam which is scanned over a moving cart. These videos were of a Lichtenberg production run by Bert Hickman who sells the Lichtenberg figures on his website: http://www.capturedlightning.com/ View the previous version of this system: Radcam1 Irradiation run videos and pictures: Radcam2 Neobeam Run |
