XUV光谱仪
XUV光谱仪是新型的像差校正平场入射X射线光谱仪,光谱范围可涵盖1-80nm.模块化设计,可以满足不同的实验条件和环境。 srS!X$cec 单光栅(标准配置)可覆盖5-80nm测量范围 $<*) 5|6 技术参数 .2I?^w&j+ • bvD}N<>3N 技术优势介绍: bQD8#Ml1 - Direct imaging of the source / Superior signal strength .!q_jl%U In contrast to conventional devices our XUV spectrometer does not 3a:Hx|

^aW This configuration typically collects 15 to 25 times more light than <^s31.&p standard versions, resulting in a signal-to-noise figure improved by the ~\=D@G,9 same ratio. #WjQ'c: In some experiments, this improved signal strength is the crucial step lIyMNw for realizing a measurement at all. eEXNEgbn 9!Av sC9 - Flat-field imaging technology ~d7t\S Our instruments are based on high quality aberration-corrected RUY7Y? flat-field gratings. In contrast to conventional gratings these focus [IHo

This allows for v4e4,Nt positioning the entire detector in the focal plane of the grating for `BmnXWMgx superior spectral resolution. 6UCF w> &G2&OFAr]q - Compactness / Modularity L9jT:2F The spectrometer is very compact and can be bolted directly to a vacuum :uo)-9_ chamber. It is capable of carrying its own weight, no table required. ZH~bY2^; There are no externally moving parts. +cfcr* Through its modular design, our spectrometer can be adapted to a number "{8j!+]4i of configurations (source distance, spectral range, detectors, vacuum h: yJ pumping, etc). This makes it highly flexible for varying requirements D%+yp and experiments. !aSj1
2J /KvJjt'8 - Robust against misalignment k86TlQRh The compact design of the spectrometer makes it inherently insensitive HGAi2+& against mechanical and environmental disturbances (vibrations, 4AN8Sx( acoustics, etc). No externally moving parts and closed-loop grating *zUK3&n~I actuators with absolute position monitoring add to the robustness and *AV%= allow for monitoring of the grating alignment at all times. JDf>Qg{ In addition, the concept of a spectrometer without entrance slit also 6y!U68L;B makes the instrument less sensitive to misalignment. Under typical ECt<\h7} operating conditions a misalignment of the beam in the dispersion m 3UK`~ji direction on the entrance of the spectrometer by 500um would lead to a D\M"bf>q1 signal reduction by more than 20% in an instrument with entrance slit 5Pf=Uj6D while it is less than 10% for our design. e?XFtIj$ e6MBy\*n - Customization .Wt3|?\=nd The adaptability of our XUV spectrometer makes it possible to highly dQT[pNp: custom-fit the device to requirements.
