A laboratory‐scale hard X‐ray microscope utilizing the portable synchrotron named MIRRORCLE‐6X is developed in our laboratory. MIRRORCLE‐6X is a X‐ray source suitable for hard X‐ray microscopy as a result of the X‐ray source size of the order of micron, and highly brilliant hard X‐rays. Furthermore, when effective focusing elements of hard X‐rays are used for MIRRORCLE‐6X, this machine could be used for non destructive inspection with high resolution of biological and engineering. We designed hard X‐ray optical elements for MIRRORCLE6X and started fabricating X‐ray mirrors. © 2004 American Institute of Physics
