RACE (Ring Accelerator Experiment)
01 Definition
Lawrence Livermore National Laboratory (LLNL) program (1991) that experimentally accelerated and focused compact toroid plasma rings in a coaxial railgun configuration. RACE was a fusion-oriented program and inspired AFRL's MARAUDER weapons program, establishing the LLNL→AFRL link in the three-lab compact toroid lineage.

Overview
LLNL's Ring Acceleration Experiment (1986-1995). Demonstrated that plasma toroids can be accelerated as armatures in a coaxial rail gun configuration. 7.4-meter-long coaxial-cone geometry, three-fold compression in radius and length, five-fold increase in magnetic field. Identified 'snowplow' gas drag as primary performance limitation. Transitioned to collaboration with Air Force Phillips Laboratory's MARAUDER program (1993-1994). The 1995 final report (LLNL, DOE Contract W-7405-Eng-48) documents the RACE→MARAUDER transition. Applications: 'fusion fueling and weapons effects generation.' This is the LLNL side of the compact toroid weapons lineage.
