Source Characteristics of Low Energy Storage Ring: MIRRORCLE-20

The low energy storage ring MIRRORCLE-20, operating at electron energy Eel = 20 MeV can produce a powerful infrared (IR) synchrotron radiation with wavelengths over mid-IR and far-IR regions. To clarify the applicability of this light source, its far-IR output as well as spectrum was measured. The IR emission is forced by a circular optics, named photon storage ring (PhSR), placed around the electron orbit, and is collected by a magic mirror associated with two plane mirrors in the storage ring. It is proven that the FIR intensity is boosted by the PhSR. The SR spectrum of MIRRORCLE-20 in the far-IR region is much broader and more intense than that of a typical black body light source, and therefore can be used for far infrared spectroscopy (FIRS).
