Indirect drive: inertial confinement fusion technique whereby the driver energy strikes the fuel capsule indirectly, i.e., by the x-rays produced by heating a high-Z enclosure (hohlraum) that surrounds the fuel capsule.

Inertial confinement fusion (ICF): concept in which a driver delivers energy to the outer surface of a pellet of fuel (typically containing a mixture of deuterium and tritium), heating and compressing it. The heating and compression then initiate a fusion chain reaction.

Inertial fusion energy: concept whereby ICF is used to predictably and continuously initiate fusion chain reactions that yield more energy than that incident on the fuel from the driver for the ultimate purpose of producing electrical power.

Krypton fluoride (KrF) laser: a gas laser that operates in the ultraviolet at 248nm.

Magnetic target fusion: ICF technique whereby a magnetic field is created surrounding the target, and the magnetic field is then imploded around the target, initiating fusion reactions.

Pulse compression: a technique whereby the incident pulse is compressed to deliver the energy in a shorter time.

Pulsed-power fusion: ICF technique whereby a large electrical current is used to magnetically implode a target.

Reactor chamber: The apparatus in which the fusion reactions would take place in an inertial fusion energy power plant, and which would contain and capture the resulting energy released from repeated ignition.

Shock ignition: ICF technique that uses hydrodynamic shocks to ignite the compressed hot spot.

Target: the fuel capsule, together with a holhraum or other energy-focusing device (if one is used), that is struck by the driver’s incident energy in order to initiate fusion reactions.
