High-tech waves
2026-01-16 - A gyrotron is essentially an energy-delivery device. Once generated in the magnetic tube, high-frequency waves travel the length of a wave guide into an antenna that directs the beam into the plasma. The effect of the high-frequency wave on the electrons in the plasma is to accelerate their motion—another way of saying that electrons are "heated" by the high frequency beam. Two gyrotrons delivered by the Japanese Domestic Agency have already been installed at ITER.
