Beta II
Critical link in transferring magnetized plasma gun physics from LANL to LLNL and AFRL.
01 Definition
Lawrence Livermore National Laboratory (LLNL) compact toroid experiment using a coaxial plasma gun. Beta II incorporated design features from the Los Alamos Scientific Laboratory (LASL) plasma gun, representing a direct LANL-to-LLNL technology transfer. The second link in the three-lab compact toroid lineage: LANL (CTX) → LLNL (Beta II) → AFRL (MARAUDER).
02 Detailed_Analysis
Beta II was a pioneering magnetic mirror and compact toroid fusion experiment operated at Lawrence Livermore National Laboratory (LLNL) during the late 1970s and 1980s. Evolved from the 2XIIB facility, Beta II incorporated a high-energy magnetized coaxial plasma gun adapted from Los Alamos Scientific Laboratory (LASL) designs. The facility was instrumental in demonstrating the formation, transport, and injection of magnetized spheromaks into mirror fields, serving as the crucial intermediate technological node in the three-lab compact toroid lineage linking LANL's CTX with AFRL's MARAUDER.
03 Key_Facts
- ▸ Operated at LLNL as the experimental successor to the 2XIIB mirror facility.
- ▸ Utilized a high-voltage magnetized coaxial plasma gun for spheromak injection.
- ▸ Direct recipient of LASL coaxial plasma gun technology and physics design.
- ▸ Served as the direct experimental predecessor to LLNL's RACE accelerator.

Overview
Beta II was a compact toroid experiment at Lawrence Livermore National Laboratory (LLNL) that used a coaxial plasma gun to form and accelerate compact toroids. The plasma gun design incorporated features of an existing Los Alamos Scientific Laboratory (LASL) plasma gun, establishing a direct technology transfer from LANL to LLNL.
Significance
Beta II represents the second link in the three-lab compact toroid lineage: LANL (CTX) → LLNL (Beta II) → AFRL (MARAUDER). The experiment extended LANL's CTX spheromak approach to higher parameters and demonstrated that compact toroids could be formed and accelerated using coaxial plasma guns at LLNL. This work directly led to the RACE (Ring Accelerator Experiment) program, which inspired AFRL's MARAUDER.
Technology Transfer
The LANL → LLNL transfer is documented through the Beta II plasma gun design, which incorporated LASL features. This is one of the earliest documented inter-laboratory compact toroid technology transfers in the investigation.
