项目摘要
The interaction of ultraintense laser pulses with matter allows producing conditions that are rele-vant to a variety of fundamental interdisciplinary research fields, which include modeling astrophysical objects such the interior of giant planets and low mass stars, or the development of compact proton accelerators for cancer therapy or as injectors for nuclear physics applications. However, this requires producing matter at Gbar pressures or accelerating the protons to very high energies, but this has so far proven experimentally challenging, especially because the mechanisms that govern the above phenomena at the microscopic levels are still poorly understood. Here, we will employ micrometer-sized hydrogen and argon droplets from a laminar liquid jet as ideal, mass-limited targets for novel studies of relativistic laser-plasma generation with respect to the above topics. More specifically, the combination of the unique features of the em-ployed droplets and of laser pulses from two different high-power laser systems in an energy range over more than two orders of magnitude will allow us, on the one side, advancing our knowledge of matter in the high energy density regime and, on the other side, greatly improving the laser-generated beam features, thus paving the way for the realization of next-stage tabletop-scale proton accelerators.
超强激光脉冲与物质的相互作用允许产生与各种基础交叉学科研究领域相关的条件,包括对诸如巨行星和低质量恒星内部的天体物理对象进行建模,或开发用于癌症治疗或核物理应用的紧凑型质子加速器。然而,这需要在GBAR压力下产生物质或将质子加速到非常高的能量,但到目前为止,这在实验上被证明是具有挑战性的,特别是因为在微观层面上支配上述现象的机制仍然知之甚少。在这里,我们将使用来自层流液体射流的微米大小的氢和氩液滴作为理想的、质量受限的目标,用于与上述主题相关的相对论激光等离子体产生的新研究。更具体地说,利用在超过两个数量级的能量范围内使用的液滴和来自两个不同高功率激光系统的激光脉冲的独特功能相结合,将使我们能够一方面推进我们对处于高能量密度区的物质的了解,另一方面将大大改善激光产生的光束特征,从而为实现下一阶段桌面规模的质子加速器铺平道路。
