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。 [w!C*_V 9 单光栅(标准配置)可覆盖5-80nm测量范围 Q| ?'(J+ 技术参数 c+g@Z"es • 7b, (\Fm 技术优势介绍: 1yMr~Fo - Direct imaging of the source / Superior signal strength In contrast to conventional devices our XUV spectrometer does not require a narrow entrance aperture but rather images the harmonic source directly onto the detector. Thus 80% or more of the incoming beam can be used for measurement. Please see 6Z?Su(s(5 http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. {WQq}-( This configuration typically collects 15 to 25 times more light than standard versions, resulting in a signal-to-noise figure improved by the lj4o#^lC same ratio. 1'JD = In some experiments, this improved signal strength is the crucial step for realizing a measurement at all. 5pfYEofK[ :Wc_Utt - Flat-field imaging technology |0g{"}% Our instruments are based on high quality aberration-corrected flat-field gratings. In contrast to conventional gratings these focus all wavelengths onto a plane rather than a circle. This allows for positioning the entire detector in the focal plane of the grating for superior spectral resolution. p$Hi[upy Y1)!lTG - Compactness / Modularity _[t8rl The spectrometer is very compact and can be bolted directly to a vacuum chamber. It is capable of carrying its own weight, no table required. o:~LF6A- There are no externally moving parts. "hQgLG Through its modular design, our spectrometer can be adapted to a number of configurations (source distance, spectral range, detectors, vacuum 4t*so~ pumping, etc). This makes it highly flexible for varying requirements and experiments. q9]IIv >P=Q #;v - Robust against misalignment U>a\j2I The compact design of the spectrometer makes it inherently insensitive against mechanical and environmental disturbances (vibrations, =n+ \\D acoustics, etc). No externally moving parts and closed-loop grating actuators with absolute position monitoring add to the robustness and .UQE{.? allow for monitoring of the grating alignment at all times. 0^3+P%(o@ In addition, the concept of a spectrometer without entrance slit also makes the instrument less sensitive to misalignment. Under typical ]Y`Ib0$ operating conditions a misalignment of the beam in the dispersion direction on the entrance of the spectrometer by 500um would lead to a u5+|Su signal reduction by more than 20% in an instrument with entrance slit while it is less than 10% for our design. r@kP* l1'6cLT` - Customization sOpep The adaptability of our XUV spectrometer makes it possible to highly custom-fit the device to requirements. Thus we offer to customize every S\=1_LDx" spectrometer to exactly match the desired research application. This includes e.g. interfacing to experimental chambers, adaption of the AXPMnbUS source distance, integration of customer-supplied detectors, user-defined filter mounts, non-magnetic instruments, special mounting Ln!A:dP}c- situations, etc. LT VF8-v VUwC-) 典型客户: {<=#*qx[Y! 1) 苏黎世联邦理工学院 _>yoX 2) The Institute of Electronic Structure and Laser of the Foundation for Research and Technology-Hellas (IESL-FORTH) *F`A S> 3) MPQ 69G`2_eKCp 4) Los Alamos ;
