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 design and performance test of an antiscattering X-ray grid that is based on photosensitive glass was conducted using MCNP simulation. The simulation was designed in three parts: source, scatterer, and grid. The source was a cone type with a single energy of 50 keV, and the scatterer was designed as a box with elemental composition and density the same as those of a human body. Three types of grid were tested: ideal, injection, and electroplating. The ideal-type grid was generally known and contained only a shielding wall, the injection-type grid had the shielding material injected into the glass, and the electroplating-type grid had the shielding material electroplated on the glass lattice skeleton. The ideal-type grid showed a scattered and primary photon ratio (SPR) of 0.106, and the nongrid type showed an SPR of 0.159. The injection-type grid had an SPR of 0.126, which corresponded to 119.3% of that of the ideal type. The electroplating-type grid had an SPR of 0.0964, which corresponded to 93.7% of that of the ideal type. It was understood that the electroplating-type grid showed the most effective reduction of the scattered photons in terms of SPR.
