摘要

摘要介绍了一种用于研究在液体喷射靶上形成的极紫外范围（EUV）激光等离子体发射特性的支架。为了形成喷射靶，使用了一个脉冲阀和不同直径的毛细管。使用 Nd:YAG 激光器（波长为 1064 nm，脉冲持续时间为 11 ns，频率高达 10 Hz，脉冲能量为 500 mJ）激发激光等离子体。为了研究发射光谱，使用了一台以绝对单位校准的镜面 X 射线光谱仪、一台 Aurora 4000 可见光范围光谱仪和一台在超紫外范围内工作的显微镜。此外，还对形成的液体射流进行拍照。介绍了支架的设计及其主要参数。还介绍了研究液体从不同喷嘴流出进入真空的过程的首次实验结果。

A Stand for Investigating Properties of Laser Plasma Formed on Liquid-Jet Targets

A stand is described that is designed to study the emission properties of laser plasma in the extreme ultraviolet range (EUV) formed on liquid jet targets. To form a jet target, a pulse valve and capillaries of various diameters are used. A Nd:YAG laser is used (with a wavelength of 1064 nm, a pulse duration of 11 ns, a frequency of up to 10 Hz, and a pulse energy of 500 mJ) to excite laser plasma. To investigate the emission spectra, a mirror X-ray spectrometer calibrated in absolute units, an Aurora 4000 visible-range spectrometer, and a microscope operating in the EUV range are used. Photographing of the formed liquid jets is also provided. The design of the stand and its main parameters are presented. The results of the first experiments to study the processes of liquid outflow from various nozzles into vacuum are also presented.
