摘要

首尔国立大学开发了用于X-pinch装置的集体汤姆森散射(CTS)诊断系统。该系统用于测量等离子体射流的各种参数，包括等离子体温度和等离子体流速。在流速测量中，对二次谐波Nd:YAG激光器和采集光学元件进行定向，以保证散射矢量与流速方向对齐。收集光学已被优化，以最大限度地提高光子效率。考虑到CTS光谱诊断对光谱色散和分辨率的要求，设计色散为0.004 nm/pixel的光谱仪。测量了系统的光谱色散和分辨率。CTS诊断系统将有助于更深入地了解X-pinch等离子体动力学，并开发先进的高能量密度等离子体(HEDP)技术。

Development of a Collective Thomson Scattering diagnostic system on SNU X-pinch device

The Collective Thomson Scattering (CTS) diagnostic system has been developed for the X-pinch device at Seoul National University. The system is designed to measure various parameters of plasma jets, including plasma temperature and plasma flow velocity. For the flow velocity measurement, the second harmonic Nd:YAG laser and the collection optics are oriented in order to ensure the scattering vector is aligned with the flow direction. The collection optics have been optimized to maximize photon efficiency. Due to the requirement of high spectral dispersion and resolution for the diagnosis of CTS spectra, the spectrometer is designed with a dispersion of 0.004 nm/pixel. The spectral dispersion and resolution of the system has been measured. The CTS diagnostic system will contribute to a deeper understanding of X-pinch plasma dynamics and the development of advanced High Energy Density Plasma (HEDP)-based technologies.
