01 Executive_Summary

Los Alamos National Laboratory (LANL) compact toroid experiment using a magnetized coaxial plasma gun to generate spheromaks. CTX established the plasma gun as a primary tool for compact toroid formation. This technology later propagated to LLNL's Beta II and RACE programs and to AFRL's MARAUDER. CTX is the foundational node of the three-lab compact toroid lineage.

Overview

CTX (Compact Toroid Experiment) was a LANL program that used a magnetized coaxial plasma gun to generate spheromaks — compact toroids with both toroidal and poloidal magnetic fields. The experiment demonstrated that spheromaks could be formed and sustained using coaxial plasma guns.

Foundational Role

CTX is the foundational node of the three-lab compact toroid lineage. The coaxial plasma gun technology developed for CTX propagated to:

Connection to FRX

CTX (spheromaks) and FRX (FRCs) were parallel programs at LANL. Together they established the two branches of compact toroid physics: spheromaks (with toroidal field) and FRCs (without toroidal field). Both descend from the same LANL research environment.
