摘要

LCLS的极端条件下物质(MEC)仪器率先使用硬x射线自由电子激光器(XFEL)与高功率光学激光器相结合,以推进高能量密度(HED)科学。自2012年作为一个开放访问的用户设施投入使用以来,MEC已经实现了一系列备受瞩目的科学成果,为动态等离子体和高压材料状态的原子和结构特性提供了新的见解。2021年,美国能源部批准了CD-1建设新的HED科学设施,并对当前MEC的激光驱动器和实验能力进行了重大升级。这种独一无二的设备将结合三个光学激光驱动器:高功率短脉冲(150J, 150fs 10Hz);100j级长脉冲(10Hz);以及LCLS XFEL的kJ长脉冲。本讲座将概述该设备的概念设计,并将其置于日益发展的高功率激光科学领域的背景下。

The Matter in Extreme Conditions Upgrade (MEC-U) Project
The Matter in Extreme Conditions (MEC) instrument at LCLS pioneered the use of the hard X-ray free electron laser (XFEL) in combination with high-power optical lasers to advance High Energy Density (HED) science. Since it was commissioned in 2012 as an open-access user facility, MEC has enabled a wide range of high-profile scientific results, providing new insight into the atomic and structural properties of dynamic plasma and high-pressure material states. In 2021, DOE gave CD-1 approval for the construction of a new HED science facility with significant upgrades in the laser drivers and experimental capabilities of the present-day MEC. This one-of-a-kind facility will combine three optical laser drivers: a high-power short pulse (150J, 150fs 10Hz); a 100J-class long pulse (10Hz); and a kJ long pulse with the LCLS XFEL. This talk will provide an overview of the facility conceptual design and place it in the context of the growing field of high-power laser science.
