Superconducting RF-new directions

In the last two years, there has been substantial progress in superconducting accelerator technology both in long term operation at many facilities as well as in high gradients at many laboratories. These rapid advances have made RF superconductivity an enabling technology for a variety of new applications. In high energy physics, low frequency (200-400 MHz) cavities are envisioned to accelerate muons for intense neutrino beams and muon colliders (200-1300 MHz). For storage ring based light sources, superconducting cavity systems (500 MHz) will upgrade the Taiwan Light Source and provide high voltage and high power for new storage rings under construction for the Canadian Light Source (CLS), DIAMOND in England, and SOLEIL (350 MHz) in France. Similar systems are envisioned for BEPC in China and for the new Shangai Light Source.
