We report on the status of the first Italian Infrared Synchrotron Radiation Beamline SINBAD (Synchrotron INfrared Beamline At DAFNE), that has been designed to work at wavelengths greater than 10 mm. SINBAD is being installed on DAFNE, the new collider of the Laboratori Nazionali di Frascati designed to work at 0.51 GeV with a beam current of 2 to 5 A. The infrared radiation extracted from a bending magnet under an angle of 50x50 mrad will be two orders of magnitude more brilliant than that of a black body at 2000 K at a wavelength of 100 mm. The beamline layout, which consists of two plane mirrors, two toroidal mirrors, and one aspherical mirror, has been designed by ray tracing simulation. In this layout one ellipsoid focuses the radiation on a wedged CVD diamond-film window, the beam is than re-focused again on the entrance of an interferometer. With a calculated transmittance of the optics between 60% and 80% at 50 mm, this beamline will allow experiments which require a very high brilliance in the far infrared.
