The P3 installation of ELI-Beamlines is conceived as an experimental platform for multiple high-repetition-rate laser beams spanning time scales from femtosecond via picosecond to nanosecond. The upcoming L4n laser beamline will provide shaped nanosecond pulses of up to 1.9 kJ at a maximum repetition rate of 1 shot/min. This beamline will provide unique possibilities for high-pressure, high-energy-density physics, warm dense matter, and laser–plasma interaction experiments. Owing to the high repetition rate, it will become possible to obtain considerable improvements in data statistics, in particular, for equation-of-state data sets. The nanosecond beam will be coupled with short sub-picosecond pulses, providing high-resolution diagnostic tools by either irradiating a backlighter target or driving a betatron setup to generate energetic electrons and hard X-rays.

P3 装置的 L4n 激光束线：在 ELI-Beamlines 上实现高重复率高能量密度物理

ELI-Beamlines 的 P3 装置被设想为一个实验平台，用于跨越从飞秒到皮秒到纳秒的时间尺度的多个高重复率激光束。即将推出的 L4n 激光束线将以 1 次/分钟的最大重复率提供高达 1.9 kJ 的成形纳秒脉冲。这条光束线将为高压、高能量密度物理、暖致密物质和激光-等离子体相互作用实验提供独特的可能性。由于高重复率，将有可能在数据统计方面获得相当大的改进，特别是对于状态方程数据集。纳秒光束将与短的亚皮秒脉冲耦合，
