Towards light sources featuring superconducting miniundulators

Abstract

Besides the exploitation of the Helios 2 superconducting compact storage ring for user operations and for its own R&D work, SSLS envisions a 4 th generation synchrotron light source to complement and, eventually, replace the current facility. This vision includes an accelerator system based on a superconducting linear accelerator with up to 5 recirculation loops for energy multiplication and recovery with the distinguishing feature that the light would be generated by superconducting mini- and micro-undulators. Under this programme, SSLS is pursuing the development of superconducting miniundulators including a proof-of-technology electron beam experiment in co-operation with the Shanghai Institute of Applied Physics and the analytical and numerical study of the fabrication tolerances of superconducting miniundulators with respect to their finite length field errors and mechanical errors. © World Scientific Publishing Company.
