SPring-8, the large synchrotron radiation facility

Inquiry number

INS-0000001688

This apparatus is an experimental irradiation system capable of exposing biological samples—such as two dimensional cultured cells, spheroids, and mice—to synchrotron X rays. In monochromatic X ray irradiation experiments conducted in the experimental hutch, monochromatic X rays with energies ranging from 10 to 90 keV can be used. X ray beams with dimensions of up to 1 mm (vertical) × 12 mm (horizontal) can be irradiated onto samples, exceeding the maximum beam size listed in the table (“X rays at the sample position”) for measurement experiments. When monochromatic X rays at 33.2 keV, which corresponds to the K absorption edge of iodine, are used, the irradiation dose rate is approximately 0.1 Gy/s. Furthermore, by installing equipment in Optical Hutch 2, irradiation experiments using white X rays can also be performed. The effective energy of the white X rays is approximately 120 keV. In white X ray irradiation experiments as well, X ray beams with dimensions of up to 3 mm (vertical) × 12 mm (horizontal) can be irradiated onto samples, exceeding the beam sizes listed in the table (“X rays at the sample position”). The dose rate of the white X rays is approximately 170 Gy/s.
