Plasma Toroid Generator
There’s a new hotness in plasma physics demos. With a sealed vessel of near-vacuum xenon and exactly the right kind of magnetic induction driver, you can conjure a shimmering toroidal halo of stable plasma. Producing the toroid effect requires high-voltage, high-frequency electronics. Compared to a typical Tesla coil the voltages are a bit lower at 600–1,000 volts, but the operating frequency is much higher at around 10–15 megahertz (MHz). This fully-open-source design is intended to be as reproducible as possible....
