「柔X光」譜出科學新篇章－－動態電子結構解析

＂Tender X-ray＂opens a new chapter in science-dynamic electronic structure analysis

TPS 32A柔X光吸收光譜光束線為國家同步幅射研究中心台灣光子源（TPS）第三期建造計畫中新建之光束線，並預計於2023年出光運轉。TPS 32A光束線光子能量範圍為1.7-11 keV，預計光通量在6keV時為10^(12)光子／秒，不僅可提供高亮度、乾淨無高諧波光子且連續可調的X光光源，搭配可執行快速能量掃描之單光儀（DCM），實驗站將支援X光吸收光譜（XAS）和硬X光光電子能譜（HAXPES）等實驗技術。除此之外，運用KB聚焦鏡可將光斑進一步縮小，使其具有微米級空間解析特性的顯微X光吸收光譜（μ-XAS）技術，這些優勢將滿足基礎科學研究與尖端科技創新，為科學界和產業界提供與時俱進的實驗設施與專業技術的研究資源，並開啟全新的研究視野。

TPS 32A tender X-ray absorption spectroscopy beamline, located the National Synchrotron Radiation Research Center, is a newly constructed in phase III of the Taiwan Photon Source (TPS) project and is expected to operate in 2023. The photon energy range of the TPS 32A beamline is 1.7-11 keV, and the expected photon flux is 10^(12) photons/sec at 6 keV. This beamline can provide high brightness, lower high harmonic photons, and a continuously tunable X-ray light source. Equipped with a double-crystal monochromator (DCM) that can perform on the fly-scan, the end station will provide experimental technologies such as X-ray absorption spectroscopy (XAS) and hard X-ray photoelectron spectroscopy (HAXPES). In addition, the use of the Kirkpatrick-Baez (KB) focusing mirror can further reduce the focal spot size and confer it with micron-level spatial resolution characteristics of micro-X-ray absorption spectroscopy (μ-XAS). These advantages will satisfy basic scientific research and cutting-edge technological innovation. The scientific and industrial circles provide experimental facilities and professional technical research resources that keep pace with the times and open up new research horizons.
