摘　　要：Z-pinch dynamic hohlraums(ZPDHs)could potentially be used to drive inertial confinement fusion targets.Double-or multishell capsules using the technique of volume ignition could exploit the advantages of ZPDHs while tolerating their radiation asymmetry,which would be unacceptable for a central ignition target.In this paper,we review research on Z-pinch implosions and ZPDHs for indirect drive targets at the Institute of Nuclear Physics and Chemistry,China Academy of Engineering Physics.The characteristics of double-shell targets and the associated technical requirements are analyzed through a one-dimensional computer code developed from MULTI-IFE.Some key issues regarding the establishment of suitable sources for dynamic hohlraums are introduced,such as soft X-ray power optimization,novel methods for plasma profile modulation,and the use of thin-shell liner implosions to inhibit the generation of prior-stagnated plasma.Finally,shock propagation and radiation characteristics in a ZPDH are presented and discussed,together with some plans for future work.
