Title: #553 Lichtenberg figures
Post by: mikeselectricstuff on December 02, 2013, 09:21:08 am
These are acrylic blocks, irradiated using a particle accelerator.

The irradiation leaves charged pathways in the plastic, which are then discharged, causing fracturing of the  plastic along the discharge path.

These guys are the masters of this - they rent time on an accelerator a few times a year to make them http://www.capturedlightning.com/ (http://www.capturedlightning.com/)

My wife gave me one a few years ago. They make great nightlights.

This one is 125mm in diameter and about 350mm tall, I acquired it about 30 years ago. It's a superb quality piece, not seen one like it for sale since.

what happens if someone aims the particle accelerator at their hand?

You get a burn right through, that cauterises the flesh in a shape exactly like the beam shape. This then will either fester and get septic ( yummy) or will turn into a solid block of scar tissue. If you are unlucky it will become malignant.

Or you will die of radiation poisoning. Unfortunately this "experiment" has been done by accident:
