Castor’s particle accelerator is a beautiful handblown glass tube that sits atop a black marble base, covered with an overhang. It’s outfitted with machined electrodes, and its transformer and vacuum are presented alongside, housed in custom component boxes.
I can’t explain it as eloquently or as scientifically accurate as they have, so let me just turn it over to them to elaborate:
When electrical current is activated and a enough of a vacuum has been formed within the tube in order for electrons to travel without striking a molecule of gas, lowmass particles accelerate to 30% of the speed of light. These electrons strike other atoms and give off light as they settle to their original energy levels.
The light first appears in arced shape, and quickly stabilizes and “flows” in a straight line across the centre of the tube. This beam of light bends around a magnet when one is placed beside the bottle, indicating the presence of the electron.
As gas molecules undergo more collisions inside the bottle, emission wavelengths appear separated out into plasma bands, demonstrating the Heisenberg Uncertainty Principle. More columns indicate that the electrons’ energy in a given state is less defined. When the vacuum dissipates, the plasma reaches its extinction point and scatters.
