Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

A new structure of RF control of plasma for electric propulsion has been proposed. With excitation characteristics of a helical antenna and propagation characteristics of waves with rotating field, both plasma production and ion heating will be expected simultaneously by employing a single helical antenna. Basic experiments to examine the proposed structure have been performed, showing consistent results with expected scenario.
