MIRRORCLE is a tabletop synchrotron light source being investigated within an EC funded project named LABSYNC. To evaluate the potential of this novel x-ray source for medical imaging applications, a set of measurements was performed at the MIRRORCLE factory in Japan.

The average electron beam current circulating in the storage ring was calculated by several methods and it was demonstrated to be in the range 0.5–1.0 µA. By comparing these values with data available for conventional x-ray tubes, the current needed to achieve the same fluence as in a standard diagnostic examination was estimated to be about 0.1–0.5 mA. Finally, results from the measurements of the electron beam size suggested that the cross section of the electron beam circulating in the storage ring is about 6 mm.

Abstract

MIRRORCLE is a tabletop synchrotron light source being investigated within an EC funded project named LABSYNC. To evaluate the potential of this novel x-ray source for medical imaging applications, a set of measurements was performed at the MIRRORCLE factory in Japan. In particular, the aim of this work was to characterize the proposed compact x-ray source by determining different parameters, such as the intensity of the broad spectra produced with thin wire targets, the size of the focal spot and its distribution. The average electron beam current circulating in the storage ring was calculated by several methods and it was demonstrated to be in the range 0.5–1.0 µA. By comparing these values with data available for conventional x-ray tubes, the current needed to achieve the same fluence as in a standard diagnostic examination was estimated to be about 0.1–0.5 mA. Finally, results from the measurements of the electron beam size suggested that the cross section of the electron beam circulating in the storage ring is about 6 mm.
