<radiobiology> A British fusion device in which scientists observed fusion neutrons in 1958.
They were erroneously considered to be thermonuclear (coming from particles with a Maxwellian velocity distribution) and were a cause for the initial optimism that fusion energy would be easy.
They were actually due to electromagnetic acceleration during a plasma instability, an effect which cannot be scaled up to produce useful energy.
