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.

The physics and technology that is being developed for and that will be demonstrated in ITER [1] will be sufficient to make a very good neutron source, there are a number of potential ‘national missions’ for a good neutron source, and the further technology advances beyond ITER that would be required for a neutron source facility are essentially the same as the advances that would be required for an electrical energy producing fusion demonstration reactor. Some preliminary considerations are presented for an alternative pathway for fusion energy development, proceeding from the present through an international test reactor (ITER) stage to a fusion neutron source facility (or non-electrical applications) stage and finally to the deployment of fusion electrical power reactors. Recent studies of two types of fusion neutron source facilities for ‘national missions’ are reviewed as representative examples.
