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.

Imperfectness of magnetic confinement in tokamak devices leads to interactions of plasma particles and radiation with the first walls and plasma facing components of fusion reactors. The most important processes are discussed. Special emphasis is given to the implantation and transport of hydrogen isotopes in solid materials.
One of the main concerns of hydrogen-material interaction is the determination of hydrogen recycling from the inner surface of the first wall, of hydrogen inventory in and hydrogen permeation through the wall of a fusion reactor. Numerical codes have been developed to calculate these properties. Hydrogen-material interaction parameters which are code input data are discussed. Some results of hydrogen isotopes inventory, recycling and permeation calculations in the next step fusion reactor ITER are presented, their accuracy is affected by the availability of data on trapping and surface processes.
