为了对低Z元素厚套筒新型Z箍缩负载等离子体、以及高压下高Z元素材料动力学过程等进行精密诊断，需要发展高亮度的脉冲软、硬X射线点光源。大电流X箍缩是一种高效低成本的可能实现方式，但目前尚存在单个软X射线点源难以稳定产生的问题，而且对硬X射线辐射特性的认识更为不足。针对此，本项目拟基于X箍缩软、硬X射线辐射的关联性，围绕大电流X箍缩演化及辐射的控制机理这一核心问题，开展兆安电流X箍缩精细演化、物理机理和调控方法的研究：从大电流X箍缩精细演化出发，进一步研究软X射线形成多点源及后续产生硬X射线辐射的物理机理，最后研究低阻抗兆安源驱动二级X箍缩等实现软X射线单点源的新方法，以及不同阻抗兆安电流源上的硬X射线点源匹配负载及其辐射特性的调控手段。通过研究可深入揭示和掌握大电流X箍缩的X射线辐射特性和调控方法，为基于X箍缩产生的高亮度软、硬X射线点光源在高能量密度物理等科学前沿领域的应用提供基础和条件。

High intensity soft and hard point X-ray sources are the key diagnostics to probe the dynamics of the newly proposed low-Z thick liner Z-pinch plasmas, high-Z materials under strong pressures, and etc. The high current driven X-pinch is a potential way to produce the high intensity soft and hard point X-ray sources with high-efficiency and low-cost. But it is difficult to form a single point soft X-ray source stably, and the understanding of the characteristics of the hard X-ray source is very limited. To solve these problems and according to the fact that soft and hard X-ray radiations from X-pinch are correlated, the researches on the fine evolutions, physical mechanics and adjusting methods of the high current driven X-pinch will be carried out. The key problem to be solved is the regulation mechanism of X-pinch’s dynamics and its radiation characteristics under high current. The investigations will be conducted in the following order: firstly, the fine evolutions of the Mega ampere X-pinch will be obtained; secondly, the formation mechanisms of the multiple hot spots and the hard X-ray radiation will be revealed; finally, the methods, such as using a Mega ampere generator with a low impedance and a two-stage X-pinch load, will be tested in order to produce a single soft X-ray point source, and the hard X-ray source’s matched load configurations under Mega ampere generators with different impedances will be obtained and the methods to adjust their radiation characteristics will be explored. The project will further help to master the radiation characteristics of the high current driven X-pinch and the methods to adjust them. These prospective achievements are supposed to provide the basis and conditions for the applications of high intensity soft and hard X-ray point sources in high energy density physics and other scientific frontiers.
