Photodetachment cross-section evaluation using asymptotic considerations
Mathematical calculations are given concerning the evaluation of the negative ions photodetachment cross-section $$\sigma $$σ, into a so-called saturation regime. The interaction between a negative…
Revamping Fusion Research
A fundamental revamping of magnetic plasma fusion research is needed, because the current focus of world fusion research—the ITER-tokamak concept—is virtually certain to be a commercial failure.…
Development of theoretical model for 3D plasma energy behavior and characteristics
In this paper, research has been conducting on calculating full plasma energy and magnetic field cross sections in static as well as in tilting position for analyzing plasma vertical displacement…
Opportunities and Challenges for Compact Fusion Energy
This work considers smaller-scale alternatives and developments which may make more rapid progress towards the much needed goal of economic, safe, clean fusion power, but still based on the tokamak.

An Acoustically Driven Magnetized Target Fusion Reactor
We propose a new acoustic compression scheme for a MTF power plant. A strong acoustic wave is produced by piston impacts. The wave focuses in liquid PbLi to compress a pre-formed FRC plasma.…
Creation of a high-temperature plasma through merging and compression of supersonic field reversed configuration plasmoids
A new device, the Inductive Plasma Accelerator, was employed to simultaneously form and accelerate two oppositely directed field reversed configurations (FRCs) where the relative velocity (600 km…
Dynamic formation of a hot field reversed configuration with improved confinement by supersonic merging of two colliding high-β compact toroids.
- PhysicsPhysical review letters
A hot stable field-reversed configuration (FRC) has been produced in the C-2 experiment by colliding and merging two high-β plasmoids preformed by the dynamic version of field- reversed θ-pinch technology with significant implications for fusion research and the physics of magnetic reconnection.
Field reversed configuration confinement enhancement through edge biasing and neutral beam injection.
- PhysicsPhysical review letters
Field reversed configurations (FRCs) with high confinement are obtained in the C-2 device by combining plasma gun edge biasing and neutral beam injection and the plasma lifetimes are extended from 1 to up to 4 ms.
