摘要

我们报道了一种坚固的微流体喷嘴的开发，能够以高达kHz的重复率产生亚微米厚度的补充液片目标，λ/20的表面平面面积至少为100 μm2，真空尺寸为6 × 1.5 mm2。对该平台进行了稳定性评估，以爆发模式发射了数百次4.3 J激光，频率为0.5 Hz，峰值强度为6 × 1020 W/cm2，总计2.9 kJ。平台的关键指标，包括薄片特性、喷嘴孔径形态和质子光谱，表明实验后液体薄片平台的性能没有明显的下降。除了将其应用于离子束技术之外，我们还概述了将该平台进一步发展为高重复率等离子体反射镜的途径。

Replenishing liquid sheet targets to enable high-intensity high-repetition-rate laser-plasma interactions for ion-beam technology.

We report on the development of a robust microfluidic nozzle capable of generating replenishing liquid sheet targets with sub-micron thickness at up to kHz repetition rates, a λ/20 surface flatness over areas of at least 100 μm2, and in-vacuum dimensions of 6 × 1.5 mm2. The platform was evaluated for stability under hundreds of 4.3 J laser shots at 0.5 Hz and 6 × 1020 W/cm2 peak intensity, delivered in burst mode, totaling 2.9 kJ on the target. The key metrics of the platform, including sheet characteristics, nozzle aperture morphology, and proton spectra, showed no measurable degradation in the performance of the liquid sheet platform following this experiment. Beyond its application to ion beam technology, we outline a pathway to further develop the capabilities of the platform into a high-repetition-rate plasma mirror.
