The design progress in a compact low aspect ratio (low A) DEMO reactor, ‘SlimCS’, and its design issues are reported. The design study focused mainly on the torus configuration including the blanket, divertor, materials and maintenance scheme. For continuity with the Japanese ITER-TBM, the blanket is based on a water-cooled solid breeder blanket. For vertical stability of the elongated plasma and high beta access, the blanket is segmented into replaceable and permanent blankets and a sector-wide conducting shell is arranged inbetween these blankets. A numerical calculation indicates that fuel self-sufficiency can be satisfied when the blanket interior is ideally fabricated. An allowable heat load to the divertor plate should be 8 MW m−2 or lower, which can be a critical constraint for determining a handling power of DEMO.

The synchrotron radiation system may be useful for evaluating microcirculatory disorders and early-stage malignant tumors in various human organs.

X-ray dark-field and bright-field imaging in the Laue geometry has been successfully demonstrated. Using a Bragg-case asymmetric monochromator that produces an X-ray beam with a 0.3 mrad divergence incident onto an object and a Laue geometry analyzer that can simultaneously provide dark-field imaging (DFI) and bright-field imaging (BFI). The DFI has only an X-ray refraction component on the object without illumination, while the BFI has reasonable illumination. This was achieved by a 1.075 mm thick silicon analyzer with 4, 4, 0 diffraction at 35 keV X-ray photon energy. An image of an insect embedded in polymethylmethacrylate, which can not be visualized by absorption, has been obtained.
