Inertial confinement fusion (ICF) is a fusion energy process that initiates nuclear fusion reactions by compressing and heating targets filled with fuel. The targets are small pellets, typically containing deuterium (2H) and tritium (3H).
This timeline of nuclear fusion is an incomplete chronological summary of significant events in the study and use of nuclear fusion.
The Laboratory for Laser Energetics (LLE) is a scientific research facility which is part of the University of Rochester's south campus, located in Brighton, New York. The lab was established in 1970 with operations jointly funded by the United States Department of Energy, the University of Rochester and the New York State government. The Laser Lab was commissioned to investigate high-energy physics involving the interaction of extremely intense laser radiation with matter. Scientific experiments at the facility emphasize inertial confinement, direct drive, laser-induced fusion, fundamental plasma physics and astrophysics using the OMEGA Laser Facility. In June 1995, OMEGA became the world's highest-energy ultraviolet laser. The lab shares its building with the Center for Optoelectronics and Imaging and the Center for Optics Manufacturing. The Robert L. Sproull Center for Ultra High Intensity Laser Research was opened in 2005 and houses the OMEGA EP laser, which was completed in May 2008.
Inertial Fusion Energy is a proposed approach to building a nuclear fusion power plant based on performing inertial confinement fusion at industrial scale. This approach to fusion power is still in a research phase. ICF first developed shortly after the development of the laser in 1960, but was a classified US research program during its earliest years. In 1972, John Nuckolls wrote a paper predicting that compressing a target could create conditions where fusion reactions are chained together, a process known as fusion ignition or a burning plasma. On August 8, 2021, the NIF at Livermore National Laboratory became the first ICF facility in the world to demonstrate this. This breakthrough drove the US Department of Energy to create an Inertial Fusion Energy program in 2022 with a budget of 3 million dollars in its first year.
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. This is quantified by the Lawson criterion. Ignition can also be defined by the fusion energy gain factor.
Magnetized liner inertial fusion (MagLIF) is an ongoing fusion power experiment being carried out on the Z Pulsed Power Facility at Sandia National Laboratories in the US. Is it one example of the broader magneto-inertial fusion approach, which attempts to compress a pre-heated plasma. The goal is to produce fusion conditions without the level of compression needed in the inertial confinement fusion (ICF) approach, where the required densities reach about 100 times that of lead.
LASNEX is a computer program that simulates the interactions between x-rays and a plasma, along with many effects associated with these interactions. The program is used to predict the performance of inertial confinement fusion (ICF) devices such as the Nova laser or proposed particle beam "drivers". Versions of LASNEX have been used since the late 1960s or early 1970s, and the program has been constantly updated. LASNEX's existence was mentioned in John Nuckolls' seminal paper in Nature in 1972 that first widely introduced the ICF concept, saying it was "...like breaking an enemy code. It tells you how many divisions to bring to bear on a problem."
Omar Hurricane is a physicist at Lawrence Livermore National Laboratory, in the thermonuclear and inertial confinement fusion design division. Hurricane completed his Ph.D. at the University of California, Los Angeles (UCLA) under the supervision of Professor René Pellat in 1994. He remained at UCLA as a postdoc under adviser Steven Cowley, studying the kink and nonlinear ballooning mode instability in high-beta plasmas until joining LLNL in 1998 as a designer in A-Division.

The history of nuclear fusion began early in the 20th century as an inquiry into how stars powered themselves and expanded to incorporate a broad inquiry into the nature of matter and energy, as potential applications expanded to include warfare, energy production and rocket propulsion.
Christine Garban-Labaune is a French plasma physicist known for her research in inertial confinement fusion.
In plasma physics, a burning plasma is a plasma that is heated primarily by fusion reactions involving thermal plasma ions. The Sun and similar stars are a burning plasma, and in 2020 the National Ignition Facility achieved a burning plasma in the laboratory. A closely related concept is that of an ignited plasma, in which all of the heating comes from fusion reactions.
