Asymmetric implosion

Definition

Asymmetric implosion refers to the non-uniform collapse of a target in inertial confinement fusion, where different parts of the target compress at varying rates due to imbalanced forces acting upon it. This phenomenon can lead to inefficient energy transfer and reduced compression, which is crucial for achieving the necessary conditions for fusion. Understanding this term helps in the analysis of target physics and the dynamics involved in implosion processes.
