First results from the SINBAD beam line at DAΦNE are reported. The SR brilliance, as measured in the far infrared at the sample position, has been compared with the one of the mercury lamp. For λ=100 μm and through an aperture of 1 mm, the gain in intensity is larger than 20. The high brilliance of the synchrotron radiation in the far-infrared is fully exploited by high-pressure experiments. Preliminary experiments with a diamond-anvil cell in the 10 GPa range are reported.
