CTX (Compact Toroid Experiment)
Established the coaxial gun method for creating high-energy, self-confined spheromaks.
01 Definition
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 and is the foundational node of the three-lab compact toroid lineage (LANL → LLNL → AFRL).
02 Detailed_Analysis
The Compact Toroid Experiment (CTX) was an influential plasma physics program at Los Alamos National Laboratory (LANL) active throughout the 1980s. CTX utilized a massive magnetized coaxial plasma gun driven by high-voltage capacitor banks to form, inject, and sustain spheromak compact toroids within flux conservers. CTX established foundational scaling laws for magnetic helicity injection, magnetic reconnection, and self-organization in closed-field plasmoids, founding the core technological lineage that later transitioned to LLNL's Beta II/RACE and AFRL's MARAUDER plasmoid accelerator.
03 Key_Facts
- ▸ Constructed and operated at Los Alamos National Laboratory in the 1980s.
- ▸ Pioneered coaxial gun helicity injection for stable spheromak formation.
- ▸ Demonstrated robust magnetic self-organization and flux-conserver confinement.
- ▸ Foundational starting node for the multi-lab compact toroid research pipeline.

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:
- LLNL's Beta II (incorporated LASL plasma gun features)
- LLNL's RACE (coaxial railgun compact toroid acceleration)
- AFRL's MARAUDER (compact toroid weapons at Shiva Star)
- HyperV/HyperJet's plasma guns (commercial PJMIF)
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.
