ABSTRACT

This chapter discusses the comprehensive review of the implosion and compression of the inertial confinement fusion target. Although the numerical simulation plays an important role in analyzing these processes, it is possible to make both the qualitative and quantitative estimation even with a simplified analysis. This chapter provides an analysis of the acceleration process of the target and shows why a shell target instead of a sphere is preferred. The degradation may depend on the target structure and/or compression scheme and it may be dangerous to draw a conclusion from a calculation of a specific example. During implosion experiments in the past several years, theorists came up against a serious difficulty in interpreting the neutron production from relatively thick D-T-filled glass microballoons; the theoretical prediction was many orders of magnitude larger than the experimental results on neutron yield.
