Infrared edge radiation beamline at Aladdin

An infrared beamline has been constructed at the 800 MeV electron storage ring, Aladdin. The beamline is located downstream of a short straight section, where it collects edge radiation produced by electrons exiting and entering the bending magnets at the ends of the straight section. Measurements at wavelengths of 1-5 /spl mu/m suggest that the edge radiation is brighter than standard synchrotron radiation. When used for Fourier transform infrared (FTIR) microspectroscopy, the signal-to-noise ratio is 20 times that measured with a glower source. Several applications of the beamline are described.
