The novel x-ray source named MIRRORCLE is based on a tabletop normal conducting synchrotron using a collision of circulating electron beam with a tiny target. It is demonstrated that the brightness is comparable to SR, its source point size can be a nano scale, the spectrum is very flat and dominated by hard compornents, and it is highly coherent. MIRRORCLE is useful for medical and industrial applications since this is tabletop and its electron energy can be less than 8MeV which supresses neutron generation. X-ray imagings taken by MIRRORCLE are demonstrated, which has many advantages compared with that of the conventional synchrotron light source. 「みらくる」と名付けた新しいX線発生装置は卓上型シンクロトロンをベースとし, 電子周回軌道上においた微少ターゲットに電子をぶつけてX線を発生する.光源点のサイズが放射光よりも遙かに小さく, 放射光並の輝度を持つのが特徴である.放射角が大きいのも特徴であり, イメージングに最適である.卓上型で容易にハードX線を出すことができることから医療用, 工業用に期待される.本校では,「みらくる」で撮像した優れたX線イメージを紹介する.
