Summary
One of the three original Project Sherwood labs (with LANL and Princeton). Home of: Astron experiment (Christofilos, 1956-1973), magnetic mirror program (Richard Post), and the National Ignition Facility (NIF) — the world's largest laser, achieving fusion ignition in December 2022. LLNL's CTR program began 1952 when Herbert York founded the lab. Richard Post led the magnetic mirror approach. The Astron was the first attempt at magnetic field reversal — direct conceptual ancestor of FRC and spheromak. After Astron cancellation (1973), spheromak concept emerged as successor. NIF achieved Q>1 (scientific breakeven) in December 2022 — first controlled fusion ignition. Referenced in 29+ corpus PDFs.
