India's fusion research, often called the 'artificial sun' project, has moved ahead with a new 82.6 GHz, 400 kW gyrotron installed in the SST-1 tokamak at the Institute for Plasma Research (IPR), Gujarat. SST-1 (Steady State Superconducting Tokamak-1) is an experimental machine that studies magnetically confined hot plasma. The gyrotron supplies up to 400 kW of radio-frequency (RF) power for electron cyclotron resonance heating (ECRH) experiments and works with an existing 42 GHz, 500 kW ECRH system. SST-1 has already achieved plasma temperatures above 200 million°C, far hotter than the Sun's core.
