FIG. 2.

(a) Top-view diagram of the optical system installed at BL3 of SACLA. The grating was installed in the Optics Hutch (OH). The x-ray mirrors (M1–M3), the GaAs wafer, the OPAL camera, the Si analyzer crystal, and the MPCCD detector were placed in Experimental Hutch 1 (EH1). (b) Schematic of the dotted area in (a). The distances among the optics are as follows: grating to M1, 8.085 m; M1 to M2, 0.35 m; M2 to M3, 0.35 m; M3 to GaAs crystal, 2.12 m; M2 to Si crystal, 2.58 m; Si crystal to MPCCD, 0.35 m.
