Diamond, a highly radiation-resistant material, is considered a nearly ideal material for radiation detection, particularly in high-energy physics. In this study, radiation damage from high-energy proton beams was induced in diamond crystal...
Integration of a rapid scanning technique into THz time-domain spectrometers for nonlinear THz spectroscopy measurements [0.03%]
一种快速扫描技术在太赫兹时域光谱仪中的应用及非线性太赫兹光谱测量
