论文摘要
我们提出了一个新型实验平台的第一个结果，该平台能够访问与包括间接驱动磁化ICF在内的主题相关的物理学。激光能量沉积；原子物理学的各种主题；和实验室天体物理学（例如，B场渗透到HED等离子体中）。该平台使用电线阵列z钉的X射线来照射硅靶，从而产生消融的等离子体的流出。烧蚀的等离子体扩展为环境，动态显着的B场（〜5 t），这些电流由流过z固定的电流支持。流出具有明确的（准1D）形态，使得通常仅在更复杂的集成方案中可用的基本过程研究。实验在喜pie脉冲动力发生器上（1.4 mA，240 ns上升时间）。在这台计算机上，电线阵列z-pinch产生一个X射线脉冲，其总能量在〜30 ns上约为15 kJ。这相当于在目标上的平均亮度温度约为10 eV。
We present first results from a novel experimental platform which is able to access physics relevant to topics including indirect-drive magnetised ICF; laser energy deposition; various topics in atomic physics; and laboratory astrophysics (for example the penetration of B-fields into HED plasmas). This platform uses the X-Rays from a wire array Z-Pinch to irradiate a silicon target, producing an outflow of ablated plasma. The ablated plasma expands into ambient, dynamically significant B-fields (~5 T) which are supported by the current flowing through the Z-Pinch. The outflows have a well-defined (quasi-1D) morphology, enabling the study of fundamental processes typically only available in more complex, integrated schemes. Experiments were fielded on the MAGPIE pulsed-power generator (1.4 MA, 240 ns rise time). On this machine a wire array Z-Pinch produces an X-Ray pulse carrying a total energy of ~15 kJ over ~30 ns. This equates to an average brightness temperature of around 10 eV on-target.
