A Dedicated Infrared Synchrotron Radiation Source at the Als

We present ideas for a storage ring dedicated to and optimized for the production of synchrotron radiation over the infrared wavelength range from 1-1000 μm. The site for the 66 m circumference ring is atop the existing ALS booster synchrotron shielding. This area provides enough floor space for both the ring and beamlines, and hutches. We plan to operate the ring in two modes: as a conventional light source and as a superradiant source in the far-IR. In the conventional mode, our design allows greater transmission of light at longer wavelengths in the far-infrared than typical light sources and significantly improves beam stability. In the superradiant mode, we hope to achieve coherent emission of synchrotron radiation over the 200-1000 μm wavelength range by shortening the bunches at very low bunch current
