New Type

The X-ray free electron laser (XFEL) is a new type of synchrotron facility, which can produce full coherent light at X-ray wavelength ranges. Its focusing system makes it possible to create an extremely intensive XFEL beam. Long-size focusing mirrors are necessary for this system from the viewpoint of X-ray radiation damage. We established the figuring system with an accuracy at the nanometre level. The focusing mirror has an elliptical curved shape with a length of 400 mm. Figure accuracy with a peak-to-valley height of 2 nm is achieved. The Kirkpatrick Baez focusing system was also designed and developed for two-dimensional focusing at Japanese XFEL.

The performance of X-ray free-electron laser beamlines may be limited by the angular aperture. Compound refractive lenses (CRLs) can be employed to prefocus the X-ray beam, thereby increasing the beamline transmission. A prefocusing CRL was implemented in the X-ray transport of the Matter under Extreme Conditions Instrument at the Linac Coherent Light Source. A significant improvement in the beamline transmission was calculated over the 3–10 keV photon energy range. At 5 keV, the relative X-ray intensity was measured and a factor of four increase was seen in the beamline transmission. The X-ray focus was also determined by the ablation imprint method.

X-ray focus optimization and characterization based on coherent scattering and quantitative speckle size measurements was demonstrated at the Linac Coherent Light Source. Its performance as a single-pulse free-electron laser beam diagnostic was tested for two typical focusing configurations. The results derived from the speckle size/shape analysis show the effectiveness of this technique in finding the focus' location, size and shape. In addition, its single-pulse compatibility enables users to capture pulse-to-pulse fluctuations in focus properties compared with other techniques that require scanning and averaging.
