摘　　要：强流高能离子束可以准等容加热任何高密度样品,制备出尺度大、状态均匀、内部无冲击波的高能量密度物质,为实验室研究高能量密度物理提供了一种独特的新手段。介绍了国内外典型的强流重离子加速器装置及其与高能量密度物理相关的关键参数设计和研究规划;展示了基于粒子和流体模拟的离子束驱动高能量密度物质产生和状态演化规律进展;介绍了一套兼具高时空分辨和高穿透力的高能电子成像诊断技术;分析了中低能区离子束与等离子体相互作用过程中的碰撞和电荷交换微观机制,以及激光加速超短超强离子束在等离子体中的非线性输运和欧姆能损机制。Intense ion beams can quasi-isometrically heat any high-density sample and generate warm dense matter(WDM)with large scale,uniform state distribution without any shock wave inside.This kind of driver provides a new opportunity for the laboratory high energy density physics(HEDP)research.The typical intense ion beam accelerators around the world,as well as their critical parameters and research plans of HEDP study are introduced.The progress of ion driven WDM generation and evolution using PIC and hydrodynamic simulations is shown.The high energy electron beam radiography technique with high spatial resolution,high temporal evolution,and high penetrating ability is also introduced.The collisional and charge transfer processes of the interaction between low-to-medium energy ion and plasma are analyzed.The nonlinear effect during the intense ion beam stopping and transportation process are presented.
