Sabot: Protective device used when injecting an IFE target into the chamber at high speed.

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

Target: 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.

Wall-plug efficiency: Energy conversion efficiency defined as a ratio of the total driver output power to the input electrical power.

Wetted wall: Fusion reactor chamber’s first wall that features a renewable, thin layer of liquid.
