LANL MAGO Collaboration

Intelligence Summary: LANL-VNIIEF MAGO Collaboration (1992-2003) — U.S.-Russia Magnetized Target Fusion Partnership

Node Identity The LANL MAGO Collaboration was an 11-year scientific partnership (1992-2003) between Los Alamos National Laboratory (LANL) and the All-Russian Scientific Research Institute of Experimental Physics (VNIIEF/Arzamas-16) focused on magnetized target fusion (MTF). The collaboration used the MAGO (Magnetized Plasma Gun) device at VNIIEF to demonstrate plasma preheating and compression for fusion applications, with LANL providing diagnostic and computational support.

Strategic Relevance This collaboration represents the most significant documented channel of scientific exchange between the U.S. and Russian nuclear weapons establishments on magnetized target fusion — the same physics underlying plasma weapons. The collaboration was explicitly framed as a nonproliferation tool: by engaging Russian nuclear weapons scientists in joint fusion research, the U.S. aimed to prevent their expertise from proliferating to third countries. However, the "energy" framing was always secondary to the weapons mission. Both LANL and VNIIEF are nuclear weapons laboratories, and the MAGO device uses explosive pulsed power to generate extreme magnetic fields (up to 240 kG) for plasma compression — the same technique applicable to compact toroid weapons. The collaboration provided both sides with insights into the other's pulsed power and plasma physics capabilities, creating a dual-use knowledge exchange channel that served both nonproliferation and weapons intelligence objectives.

Technical Focus / Capabilities The MAGO device at VNIIEF used explosive flux compression generators to drive plasma preheating and compression in a magnetized target fusion configuration. Key parameters included 200 MJ stored energy, 200 MA current, and 9 MA plasma current. LANL provided the MACH2 and MHRDR computational codes for magnetohydrodynamic (MHD) modeling, diagnostic instruments, and analytical expertise. The collaboration demonstrated the feasibility of plasma preheating and compression at explosive-driven energy scales — directly relevant to both fusion energy and compact toroid weapon formation. Irvin R. Lindemuth of LANL's X-1 division was a key participant, presenting results at the 1st International Symposium for Evaluation of Current Trends in Fusion Research in 1994.

Network Linkage The LANL MAGO Collaboration connects VNIIEF/Arzamas-16 to LANL and PPPL through the MAGO Program. It represents the international exchange channel that links Russia's nuclear weapons fusion research to the U.S. MTF/FRCHX development lineage. The collaboration's dual-use nature — nonproliferation cover with weapons-relevant physics exchange — mirrors the pattern seen in the Doverie proposal and in Russia's broader strategy of leveraging international fusion collaboration (ITER, PPPL) for technology access.
