MIT spin-off Quaise is trying to use hijacked fusion technology to drill some of the deepest holes in history, unlocking ...

"Most advanced of its kind in the world." Scientists make progress on ultra-futuristic device that could generate virtually ...

Abstract: In this article, a diode magnetron injection gun (MIG) with an external anode for Ka-band gyrotron traveling wave tubes (gyro-TWTs) is designed, whose anode is demountable. The magnet bore ...

A 1 MW gyrotron, developed and manufactured by Kyoto Fusioneering in Japan, has been delivered to Tokamak Energy’s ST40 spherical tokamak facility. “ The new gyrotron will generate high ...

It will also be used to start up and drive plasma current. Using a gyrotron a beam of electrons travels through a strong magnetic field which accelerates them to the point where they emit microwave ...

Abstract: A cusp gun with two coaxial control electrodes biased at different voltages was optimized through parametric simulations for a gyrotron traveling-wave amplifier aiming to achieve an output ...

A startup has unearthed a solution: A gyrotron heat ray to melt rocks (sort of). This is a well-established nuclear fusion technology being reapplied to geothermal energy. Could it unlock the true ...
