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。 h 8<s(WR 单光栅(标准配置)可覆盖5-80nm测量范围 :|\[a0ZL
技术参数 = R n • UGxF}Q 技术优势介绍: Sim$:5P - 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 vA{DF{S4 http://www.hoerlein-partner.com/#!services/cihc for a sketch drawing. QFB2,k6jN This configuration typically collects 15 to 25 times more light than standard versions, resulting in a signal-to-noise figure improved by the 8%`h:fE same ratio.
z5_jx&^Z In some experiments, this improved signal strength is the crucial step for realizing a measurement at all. ?AVnv(_ "yK)9F[9Mo - Flat-field imaging technology \qDY0hIv t 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. [x%8l,O
#l cSBS38> - Compactness / Modularity CD.
XZA[ 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. HqI[]T@ There are no externally moving parts. V`0Y
p Through its modular design, our spectrometer can be adapted to a number of configurations (source distance, spectral range, detectors, vacuum pxI[/vS
N pumping, etc). This makes it highly flexible for varying requirements and experiments. M96Nt&P` ?Ld:HE - Robust against misalignment P_P~c~o The compact design of the spectrometer makes it inherently insensitive against mechanical and environmental disturbances (vibrations, = Qn8Y`U acoustics, etc). No externally moving parts and closed-loop grating actuators with absolute position monitoring add to the robustness and sY[!=` @ allow for monitoring of the grating alignment at all times. rM4Ri}bS In addition, the concept of a spectrometer without entrance slit also makes the instrument less sensitive to misalignment. Under typical

WZ operating conditions a misalignment of the beam in the dispersion direction on the entrance of the spectrometer by 500um would lead to a /eBcPu"[Vb signal reduction by more than 20% in an instrument with entrance slit while it is less than 10% for our design. E Uq6)

y#P_ }Kfo - Customization p
m<K6I The adaptability of our XUV spectrometer makes it possible to highly custom-fit the device to requirements. Thus we offer to customize every <vzU}JA\ spectrometer to exactly match the desired research application. This includes e.g. interfacing to experimental chambers, adaption of the &Z}}9dd source distance, integration of customer-supplied detectors, user-defined filter mounts, non-magnetic instruments, special mounting Q>xp 90&.n situations, etc. @.=2*e.z|b l}FA&c" 典型客户: ^Ge|tBMoKE 1) 苏黎世联邦理工学院 5>:p'zI 2) The Institute of Electronic Structure and Laser of the Foundation for Research and Technology-Hellas (IESL-FORTH) U ZL-mF:)& 3) MPQ c],Zw 4) Los Alamos o9v.]tb 5) Max Planck Institute 2h)* {M23a
