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。 '[u=q

N6-V - Direct imaging of the source / Superior signal strength w, 0tY=h6 In contrast to conventional devices our XUV spectrometer does not ]+\@_1<ZI require a narrow entrance aperture but rather images the harmonic source MFHPh8P directly onto the detector.

Please see G?-27Jk8 http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. uM0!,~&9| This configuration typically collects 15 to 25 times more light than oOk.Fq standard versions, resulting in a signal-to-noise figure improved by the DbSl}N ; same ratio.

In contrast to conventional gratings these focus W>b(hVBE all wavelengths onto a plane rather than a circle. This allows for I`h9P2~ positioning the entire detector in the focal plane of the grating for N"|^AF superior spectral resolution. {]ZZ] Kq/W-VyGh - Compactness / Modularity 6y)xMX The spectrometer is very compact and can be bolted directly to a vacuum bAeN>~WvY chamber. It is capable of carrying its own weight, no table required. 8F0+\40 There are no externally moving parts. TX{DZ# Through its modular design, our spectrometer can be adapted to a number u(JC 4w' of configurations (source distance, spectral range, detectors, vacuum qs6yEuh# pumping, etc). This makes it highly flexible for varying requirements jIMaPT and experiments. zypZ3g{vz <[xxCW(2 - Robust against misalignment uR"srn;^ The compact design of the spectrometer makes it inherently insensitive `>RJ*_aKEI against mechanical and environmental disturbances (vibrations, Tgp}k%R~ acoustics, etc). No externally moving parts and closed-loop grating /_rAy actuators with absolute position monitoring add to the robustness and '#<?QE!d2 allow for monitoring of the grating alignment at all times.

Under typical k]x64hgm operating conditions a misalignment of the beam in the dispersion =mCUuY# direction on the entrance of the spectrometer by 500um would lead to a k%QhF] signal reduction by more than 20% in an instrument with entrance slit zQxZR}' while it is less than 10% for our design. w5jH#ja UuxWP\~2 - Customization 7dX1.}M<( The adaptability of our XUV spectrometer makes it possible to highly xc R custom-fit the device to requirements.
