===National Ignition Facility=== [[File:U.S. Department of Energy - Science - 115 057 004 (17974887118).jpg|thumb|National Ignition Facility target chamber]] The resulting 192-beam design, dubbed the [[National Ignition Facility]], started construction at LLNL in 1997. NIF's main objective is to operate as the flagship experimental device of the so-called [[Stockpile stewardship|nuclear stewardship program]], supporting LLNLs traditional bomb-making role.
