Lawrence Livermore National Laboratory in the context of "Nuclear arms race"

The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research facility, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain. It achieved the first instance of scientific breakeven controlled fusion in an experiment on December 5, 2022, with an energy gain factor of 1.5. It supports nuclear weapon maintenance and design by studying the behavior of matter under the conditions found within nuclear explosions.

NIF is the largest and most powerful ICF device built to date. The basic ICF concept is to squeeze a small amount of fuel to reach the pressure and temperature necessary for fusion. NIF hosts the world's most energetic laser, which indirectly heats the outer layer of a small sphere. The energy is so intense that it causes the sphere to implode, squeezing the fuel inside. The implosion reaches a peak speed of 350 km/s (0.35 mm/ns), raising the fuel density from about that of water to about 100 times that of lead. The delivery of energy and the adiabatic process during implosion raises the temperature of the fuel to hundreds of millions of degrees. At these temperatures, fusion processes occur in the tiny interval before the fuel explodes outward.

Jericho (Hebrew: יריחו, romanized: Yericho) is a general designation given to a loosely related family of deployed ballistic missiles developed by Israel since the 1960s. The name is taken from the first development contract for the Jericho I signed between Israel and Dassault in 1963, with the codename as a reference to the Biblical city of Jericho. As with some other Israeli high tech weapons systems, exact details are classified, though there are observed test data, public statements by government officials, and details in open literature especially about the Shavit satellite launch vehicle.

The later Jericho family development is related to the Shavit and Shavit II space launch vehicles believed to be derivatives of the Jericho II MRBM and that preceded the development of the Jericho III ICBM. The Lawrence Livermore National Laboratory in the US concluded that the Shavit could be adapted as an ICBM carrying a 500 kg warhead over 7,500 km. Additional insight into the Jericho program was revealed by the South African series of missiles, of which the RSA-3 are believed to be licensed copies of the Jericho II/Shavit, and the RSA-4 that used part of these systems in their stack with a heavy first stage. Subsequent to the declaration and disarming of the South African nuclear program, the RSA series missiles were offered commercially as satellite launch vehicles, resulting in the advertised specifications becoming public knowledge.

Livermorium is a synthetic chemical element; it has symbol Lv and atomic number 116. It is an extremely radioactive element that has only been created in a laboratory setting and has not been observed in nature. The element is named after the Lawrence Livermore National Laboratory in the United States, which collaborated with the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, to discover livermorium during experiments conducted between 2000 and 2006. The name of the laboratory refers to the city of Livermore, California, where it is located, which in turn was named after the rancher and landowner Robert Livermore. The name was adopted by IUPAC on May 30, 2012. Six isotopes of livermorium are known, with mass numbers of 288–293 inclusive; the longest-lived among them is livermorium-293 with a half-life of about 80 milliseconds. A seventh possible isotope with mass number 294 has been reported but not yet confirmed.

In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 16 as the heaviest chalcogen, but it has not been confirmed to behave as the heavier homologue to the chalcogen polonium. Livermorium is calculated to have some similar properties to its lighter homologues (oxygen, sulfur, selenium, tellurium, and polonium), and be a post-transition metal, though it should also show several major differences from them.

A slapper detonator, also called exploding foil initiator (EFI), is a detonator developed by Lawrence Livermore National Laboratory, US Patent No. 4,788,913 (Filed 1971, Granted 1988). It is an improvement over the earlier exploding-bridgewire detonator. Instead of directly coupling the shock wave from the exploding wire (as the bridgewire does), the expanding plasma from an explosion of a metal foil drives another thin plastic or metal foil called a "flyer" or a "slapper" across a gap, and its high-velocity impact on an explosive (for example, PETN or hexanitrostilbene) then delivers the energy and shock needed to initiate a detonation. Normally all the slapper's kinetic energy is supplied by the heating (and hence expansion) of the plasma (the former foil) by the current passing through it, though constructions with a "back strap" to further drive the plasma forward by magnetic field also exist. This assembly is quite efficient; up to 30% of the electrical energy can be converted to the slapper's kinetic energy. The device's name is derived from the English word "slap".

The initial explosion is usually caused by explosive vaporization of a thin metal wire or strip, by driving several thousand amperes of electric current through it, usually from a capacitor charged to several thousand volts. The switching may be done by a spark gap or a krytron.
