Abstract

A compact X-ray ring of about 13 m diameter with two multipole 12-T superconducting wigglers is proposed as 34-keV photon sources for Didital Subtraction Angiography (DSA) of the hospital scale making use of the electron undulating method which allows a uniform wide-area exposure of human heart to 34-keV photons. The whole facility including the 1.5-GeV compact conventional type ring of triplet-achromat type lattice, two compact wigglers, two short beam lines (several meters long), and a short electron injector can be installed in a space of about 30 m square. A twenty cycle expansion of the exposed area of 33~ 34 keV photons to human heart is most effectively achieved by the combination of the electron undulating method and the asymmetric crystal diffraction method. A photon fluence rate of more than 2.4x 10¹⁴ photons/s with a 0.1% photon energy spread can be expected for a horizontal opening angle of 10 mrad, at a stored beam current of 0.5 A, by using a wiggler consisting of three magnets plus two magnets of half the deflection on either end of the wiggler.
