Adiabatic Compression
Compression of a plasma in which no heat is exchanged with the surroundings, causing temperature to rise with density. The 1983 LANL paper on adiabatic compression of FRCs is foundational to the CFR lineage.

Project Sherwood established
The U.S. AEC's classified controlled-fusion program begins at LANL and partner labs.
Christofilos begins Astron experiment at LLNL
Greek engineer starts E-layer field reversal concept. Earliest compact torus conception. Presented at 1958 Geneva.
Christofilos Astron experiment at LLNL
The Astron experiment established the field-reversed configuration geometry that prefigured modern FRC research.
First Formal Documentation of FRC Topology
H.A.B. Bodin publishes a paper in Nuclear Fusion describing 'reversed field loops' within a theta-pinch, providing physical evidence of the FRC state.
Inertial-Confinement Flux-Trapping Model Proposed
T.S. Green and A.A. Newton propose that magnetic flux is lost via rapid convection at the radial Alfvén speed, a foundational theory for FRC formation.
Discovery of FRC Anomalous Stability
Experiments at LANL discover that Field-Reversed Configurations (FRCs) are significantly more stable than predicted by MHD theory.
Astron experiment funding cancelled at LLNL
16-year project ends without achieving field reversal. Compact torus concept disperses to spheromak and FRC research.
Christofilos Astron experiment cancelled at LLNL
17-year Astron project ends. Field reversal concept disperses to LANL (FRC) and LLNL/PPPL (spheromak).
