JYE-ro-tron

Definition

A high-powered vacuum tube device that generates electromagnetic waves in the microwave frequency range, used in fusion reactors to heat plasma.

Etymology

The word is a portmanteau derived from 'gyro'—referring to the gyration of electrons in a magnetic field—and the suffix '-tron', which is common for electronic vacuum tube devices.

In the news

In the article, the PACMAN framework manages six gyrotrons simultaneously to heat plasma, allowing researchers to achieve optimal fusion performance in real time.
