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 set of thermodynamic properties of high-temperature, weakly nonideal Flinabe (LiF-NaF-BeF2) gas is calculated and presented. High-temperature Flinabe gases (plasmas) appear in the inertial fusion energy chamber over a wide range of temperatures and pressures due to the absorption of X-rays and debris, emitted from the target microexplosion, within a very thin surface layer of the Flinabe liquid wall. The equation-of-state (EOS) and ionization equilibrium data of the resulting high-temperature gas were computed and are presented in another paper. In this paper, the set of thermodynamic properties (specific enthalpy, specific heats, adiabatic exponent, and sound speed) that are required, in conjunction with the Flinabe EOS, to perform gas dynamics calculations and the required assessments of many research and development issues in nuclear fusion is modeled and computed consistently with the previously presented EOS and ionization equilibrium data. This set of Flinabe thermodynamic properties is missed in the literature, and the need to model and estimate these properties seems to be immediate rather than justifiable. Computational results for Flinabe thermodynamic properties are presented and discussed. These properties have been presented as a set of isobars that have been validated by obtaining the limiting conditions at very high temperatures for a fully dissociated/fully ionized gas.
