Developing an RF-Power Coil for a Thermonuclear Reactor

International Thermonuclear Experimental Reactor

The International Thermonuclear Experimental Reactor (ITER) had recently presented the Insulator Seal division of MDC Vacuum Products, LLC, with the prospect to manufacture a 10 kW RF-power coil.

The ITER tokamak reactor will be the largest and most powerful fusion device throughout the world. It is designed to produce 500 MW of power for 50 MW of input heating power (a power amplification ratio of 10). It will go down in history as the first ever fusion device to create net energy.
