nif
Summary
World's largest laser at LLNL — three football fields could fit inside. 192 laser beams, 351 nm UV. Primary mission: NNSA Stockpile Stewardship Program (weapons). Secondary: inertial fusion energy (IFE) research. DECEMBER 5, 2022: First controlled fusion ignition in history. Shot N221204: 2.05 MJ laser input → 3.15 MJ fusion output (target gain 1.5). Published in PRL February 5, 2024 (cover article). August 2021: 1.35 MJ yield (threshold of ignition, gain 0.72). Subsequent shots: >8 MJ yield (6x 2021 record). Key design changes: shrunk laser entrance holes, re-adjusted x-ray symmetry, 6-micron capsule thickness increase, 8% laser energy boost. 'Culmination of more than five decades of research.' NIF ignition enables all laser IFE commercial efforts: Focused Energy (proton fast ignition), Xcimer (KrF excimer). Indirect drive: laser → hohlraum → X-rays → compress fuel capsule (peppercorn-sized).

Kenneth Arnold (June 24, 1947): nine objects over Mt. Rainier, coined 'flying saucer,' started modern UFO era, led to Operation Sign
Private pilot. Nine objects. 1,200+ mph (supersonic pre-sound barrier). No tails. 'Like Chinese kite.' Coined 'flying saucer' (reporter misquote). Nationwide wave by July 4. Led to Operation Sign → Grudge → Blue Book. 2 weeks before Roswell.
