FRCHX at Shiva Star
FRCHX at Shiva Star — AFRL/LANL FRC compression experiment
01 Executive_Summary
The Field-Reversed Configuration Heating Experiment (FRCHX) was a joint AFRL-LANL magnetized target fusion (MTF) experiment conducted at the Shiva Star capacitor bank facility at AFRL Kirtland AFB, New Mexico, from approximately 2007 to 2016. FRCHX used the Shiva Star pulsed power system (9.5 MJ, 120 kV, ~90 MA short-circuit current — the world's highest-energy fast capacitor bank) to form, translate, and compress FRC plasmas via aluminum liner implosion. The experiment represents the direct lineage successor to the classified MARAUDER compact toroid weapons program (1989-1995) at the same facility.
02 Definition
A pulsed-power facility at the Air Force Research Laboratory (AFRL) on Kirtland AFB, Albuquerque, NM. Originally built in the 1970s for nuclear weapons effects simulation, Shiva Star stores up to 10 megajoules of energy and discharges it in microseconds. It was used for magnetized target fusion experiments, including the AFRL Shiva Star implosion experiments that compressed FRC plasmas to high densities.

Intelligence Summary: FRCHX at Shiva Star — AFRL/LANL FRC Compression Experiment
Node Identity: The Field-Reversed Configuration Heating Experiment (FRCHX) was a joint AFRL-LANL magnetized target fusion (MTF) experiment conducted at the Shiva Star capacitor bank facility at AFRL Kirtland AFB, New Mexico, from approximately 2007 to 2016. FRCHX used the Shiva Star pulsed power system (9.5 MJ, 120 kV, ~90 MA short-circuit current — the world's highest-energy fast capacitor bank) to form, translate, and compress FRC plasmas via aluminum liner implosion. The experiment represents the direct lineage successor to the classified MARAUDER compact toroid weapons program (1989-1995) at the same facility.
Strategic Relevance to FRC/Plasma Weapons Context: FRCHX is the critical bridge node between the classified MARAUDER weapons program and the alleged Lockheed Martin Skunk Works Compact Fusion Reactor (CFR) program. The underlying physics is nearly identical: both MARAUDER and FRCHX involve forming a compact toroidal plasma configuration and compressing it using electromagnetic energy from the same Shiva Star capacitor bank. MARAUDER aimed to accelerate the compact toroid as a projectile weapon; FRCHX aimed to compress the FRC (a compact toroid with reversed poloidal field) for fusion. The expertise, diagnostics, and MHD simulation tools (MACH2 code) carried directly from MARAUDER to FRCHX. Intelligence assessment concludes with high confidence that FRCHX technology was not terminated but successfully transitioned to a classified program at Lockheed Martin Skunk Works around 2014-2016, based on the disappearance of public records and strategic dispersal of the core scientific team.
Technical Focus / Capabilities: FRCHX formed FRC plasma via reversed-field theta pinch, translated it into an aluminum liner, and compressed it via liner implosion driven by Shiva Star. Key results: achieved world-record FRC density (>10^18 cm^-3) and megabar pressures; FRC was radially compressed by a factor of 10 (400x compression to 540 Tesla); but temperatures only reached 300-400 eV versus the intended several keV. The critical limitation was FRC trapped flux lifetime (~13-16 μs), which was too short for complete compression heating. The 2011 AFRL/LANL report investigated RF pre-ionization and bank parameter scans to extend plasma stability. The CRADA final report (OSTI 1330817, August 8, 2016) marked the formal end of the collaboration. Key personnel: Dr. James Degnan (AFRL Fellow, Shiva Star chief), Dr. Glen Wurden (LANL).
Network Linkage: FRCHX at Shiva Star connects to 5 entities: MARAUDER (same facility, same physics — compact toroid formation/compression; MARAUDER went classified after 1995, FRCHX continued the lineage openly); Shiva Star Status (facility still operating 2024-2025 at AFRL Kirtland Building 322); Skunk Works CFR Program (FRCHX FRC plasma uses same configuration as CFR high-beta confinement; assessed transition of technology to classified Lockheed program ~2016); FRCHX Results (540T compression, 400x, world-record FRC density but insufficient lifetime); Princeton Fusion (PFRC spheromak/FRC research — same plasma family). The MARAUDER→FRCHX→CFR progression represents the most documented evidence chain for the transition of open FRC research to classified compact fusion weapons/propulsion development.
