Russian-US Magnetic Flux Compression Collaboration between Los Alamos and Arzamas-16 - 1995
This document outlines the collaborative efforts between the Los Alamos National Laboratory (LANL) and the All-Russian Scientific Research Institute of Experimental Physics (VNIIEF) in the mid-1990s, focusing on magnetic flux compression technology.
🔑 Key points from the report include:
Objective of Collaboration: Following the end of the Cold War, the U.S. and Russia initiated "lab-to-lab" interactions between their nuclear weapons design laboratories. Both institutes sought to apply their specialized knowledge of magnetic flux compression—converting chemical energy from high explosives into intense electrical pulses and concentrated magnetic energy—to fundamental scientific research.
Technical Capabilities: The report highlights VNIIEF’s significant technological achievements, which were largely unrecognized in the U.S. prior to the collaboration. These include the ability to produce:
Electrical currents exceeding 200 MA.
Inductively stored magnetic energies of 200 MJ.
Magnetic fields exceeding 10 MG in useful volumes.
🔑 Key Systems: Much of the research centered on the Disk Explosive Magnetic Generator (DEMG). The document describes these generators as modular, with various sizes (25 cm, 40 cm, and 100 cm diameters) capable of scaling to massive outputs; a 3-module, 100-cm DEMG reportedly produced 100 MJ at 256 MA.
Experimental Focus: Joint experimental campaigns investigated:
Imploding Liners: Using magnetically accelerated liners to generate ultrahigh pressures for material research.
Soft X-Ray Production: Exploring the "Changing Mass Liner" (CML) concept as a potentially more stable and simpler alternative to traditional high-voltage pulsed power approaches for x-ray generation.
Plasma Physics: Formation of hot, neutron-generating plasmas.
Significance: The paper notes that this collaboration provided U.S. scientists with access to unique, high-performance Russian pulsed power systems and served as a model for further scientific partnership between the two nations' nuclear institutes.
