Biomedical imaging center in SPring-8

A medical application subgroup of The SPring-8 Users Society drew up a plan of a building design for a Biomedical Imaging Center (BMIC) in cooperation with RIKEN.11Japanese abbreviation of the Institute for Physical and Chemical Research. our experiences of more than 15 years in this field we have found that various energies of monochromatic X-rays, strong photon densities, as well as large exposure fields are necessary, and will thus implement them in the BMIC. We therefore proposed the installation of an undulator and a wiggler. The BMIC is located 200 m from the light source to obtain a 20 cm-wide exposure field supposing that the wiggler device is installed at the light source. White X-rays from the undulator irradiate a target element generating fluorescent, semi-monochromatic, and widely spread X-rays. Monochromatic X-rays, Kα, may be specifically extracted by cutting off the Kβ component. A monochromatic undulator beamline is now being constructed. The last light source should be the wiggler to cover a wide range of medical applications.
