(a) The NSLS X25 beamline layout highlighting the locations of MGU: mini-gap undulator; FEA: the water-cooled front-end aperture; wBPM: white-beam position monitor; DCM: sagittally focusing double-crystal monochromator; mBPM: monochromatic-beam position monitor; VFM: vertically focusing mirror; IG: ionization gauge; DIFF: diffractometer assemble (ω spindle, slit apertures, cryostream, fluorescent counter); Aut: automounter; P6M: Dectris pixel-array detector. (b) View of the endstation. Close-up of the mini-κ goniometer; at its maximum open angle, κ is offset from ω by 42°. |
