Commissioned in May 2004 on the SLS machine, the LUCIA beamline was moved to the synchrotron SOLEIL during the summer of 2008. To take advantage of this new setting several changes to its design were introduced. Here, a review of the various improvements of the mechanics and, mostly, of the optics is given. Described in detail are the results of a new multilayer grating monochromator implemented on the Kohzu vessel already holding the two-crystal set-up. It consists of a grating grooved onto a multilayer (replacing the first crystal) associated to a multilayer (as a second crystal). It allows a shift of the low-energy limit of the beamline to around 500 eV with an energy resolution and a photon flux comparable with those of the previous couples of crystals (KTP and beryl).
LUCIA光束线于2004年5月在SLS机器上投入使用,2008年夏天迁至同步加速器SOLEIL。为利用这一新环境,对其设计进行了多项更改。在此,对机械部分尤其是光学部分的各种改进进行了综述。详细描述了在已装有双晶装置的小泽容器上实现的新型多层光栅单色仪的结果。它由刻在多层上的光栅(取代第一块晶体)与多层(作为第二块晶体)组成。它可使光束线的低能极限移至约500 eV,其能量分辨率和光子通量与之前的晶体对(磷酸钛氧钾和绿柱石)相当。
