01 Definition

Naval Research Laboratory (NRL) fusion reactor concept (1971) involving a rotationally stabilized liquid lead-lithium liner and mechanical compression. CFS-NM's spinning liquid-metal liner (SLC) concept has strong conceptual similarities to LINUS, connecting the NRL liner approach to modern commercial fusion.

02 Detailed_Analysis

LINUS was a groundbreaking magneto-inertial fusion (MIF) concept developed at the Naval Research Laboratory (NRL) in the 1970s under the leadership of Anthony Robson and Jay Boris. The concept utilized a mechanically or pneumatically driven, rotationally stabilized liquid metal liner (composed of molten lead-lithium) to radially compress a closed-field plasma target, such as a field-reversed configuration (FRC). LINUS uniquely addressed first-wall neutron damage and tritium breeding simultaneously, directly informing modern commercial MTF architectures including CFS-NM's Spinning Liquid-metal Liner.

03 Key_Facts

  • ▸ Developed at the Naval Research Laboratory during the 1970s.
  • ▸ Used a rotationally stabilized liquid lead-lithium liner for reversible compression.
  • ▸ Mitigated structural material activation and first-wall ablation via fluid walls.
  • ▸ Direct physics and engineering ancestor to modern liquid-metal liner fusion.

Overview

LINUS was an NRL fusion reactor concept from 1971 that used a rotationally stabilized liquid lead-lithium liner to compress plasma for fusion. The liquid metal liner was spun to provide rotational stabilization, preventing Rayleigh-Taylor instabilities that plague solid liner approaches.

Connection to CFS-NM

CFS-NM (Compact Fusion Systems New Mexico) was founded by Peter Turchi in 2017. CFS-NM's spinning liquid-metal liner (SLC) concept has strong conceptual similarities to LINUS. Turchi's 42-year career connects LASL (1975), AFRL Shiva Star (1980s-1990s), Atlas (2000s), and CFS-NM (2017), linking the LASL Fast Liner, NRL LINUS, AFRL MARAUDER, and CFS-NM SLC across four decades.

Lineage

NRL LINUS → CFS-NM SLC represents a separate but related lineage to the LANL → LLNL → AFRL compact toroid lineage. Both lineages involve liner compression of plasma, but LINUS/SLC uses liquid metal while FRCHX uses solid aluminum liners.
