Astron (Christofilos Fusion Experiment)
01 Executive_Summary
Astron was a 1960s magnetic-confinement fusion concept proposed by Nicholas Christofilos at Lawrence Livermore National Laboratory (LLNL). It used a relativistic electron beam to create a field-reversed configuration for plasma confinement. Astron is a direct precursor to modern FRC research and the compact-toroid lineage, establishing the field-reversed geometry that LANL later refined through the FRX experiments.
