Title Optimisation of Superconducting Undulators for X-ray FELs
Abstract When superconducting undulators (SCUs) are optimised specifically for Free Electron Lasers (FELs) rather than storage rings a number of interesting implications emerge. In particular these relate to the vacuum requirement, the heat deposition within the SCU due to wakefield effects, and the undulator geometry itself. The impact of these considerations is that the peak field level achievable in an SCU specifically optimised for an FEL is significantly enhanced. For example, a planar SCU, utilising NbTi, with a 15mm period and 5mm aperture optimised for an FEL instead of a storage ring will generate a peak field of 2.1T compared to 1.4T. This radical increase in undulator performance will have a major impact on the optimisation of future X-ray FELs. This paper describes how an SCU for an X-ray FEL will be able to generate magnetic field levels far beyond those currently foreseen by any other magnet technology. It will also describe the prototype SCU being assembled now in the UK and the planned demonstration with beam on the CLARA test accelerator in early 2018.
