线阵Z箍缩作为实验室中最强的X射线源，在惯性约束聚变、实验室天体物理和其他高能密度应用中具有重要意义。为了产生更大功率和更高效率的X射线，人们对线阵的动力学特性进行了广泛的研究，并提出了各种方法来改善线阵的内爆质量。本文综述了电爆炸丝和Z箍缩的电介质涂层效应的实验和理论研究。自2000年初以来，人们对与丝阵Z箍缩第一阶段有关的电线爆炸进行了广泛的研究，结果表明，电介质涂层可以显著增加初始阶段电线中的焦耳能量沉积，甚至可以实现钨丝的无电晕爆炸。近年来，绝缘线阵Z箍缩的动力学研究受到越来越多的关注。通过施加介电涂层，烧蚀过程被抑制，X射线开始时间被延迟，并且多峰辐射的可能性被降低。这篇评论是由线阵Z箍缩的演化动力学，并广泛介绍了相关的科学概念和各种其他应用。根据目前的研究现状，提出了介质涂层Z箍缩负载面临的挑战、机遇和发展方向，以期进一步推动介质涂层Z箍缩负载的研究和应用。
As the most powerful x-ray source in the laboratories, the wire array Z pinches have been of great relevance to inertial confinement fusions, laboratory astrophysics, and other high-energy density applications. In order to produce x-ray with greater power and higher efficiency, the dynamics of wire array has been investigated extensively, and various methods have been proposed to improve the implosion quality of the wire array. This review focuses on the experimental and theoretical investigations regarding the effects of the dielectric coatings on electrical exploding wires and Z pinches. Since the early 2000, the electrical wire explosion related to the first stage of the wire array Z pinches has been studied extensively, and the results indicated that the dielectric coatings can significantly increase the joule energy deposition into a wire in the initial stage, and even the corona free explosion of tungsten wires can be achieved. Recently, there is an increasing interest in the dynamics of insulated wire array Z pinches. By applying dielectric coatings, the ablation process is suppressed, the x-ray start time is delayed, and the possibility of multi-peak radiation is decreased. This review is organized by the evolution dynamics of wire array Z pinches, and a broad introduction to relevant scientific concepts and various other applications are presented. According to the current research status, the challenges, opportunities and further developments of Z pinch loads using dielectric coatings are proposed to further promote the researches and their applications.
