Superconducting Insertion Devices with Switchable Period Length — •Tomas Holubek¹, Tilo Baumbach¹, Sara Casalbuoni¹, Stefan Gerstl¹, Andreas Grau¹, Michael Hagelstein¹, David Saez de Jauregui¹, Cristian Boffo², and Wolfgang Walter² — ¹Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany — ²Babcock Noell GmbH, Wuerzburg, Germany

Superconducting insertion devices (IDs) are very attractive for synchrotron light sources since they offer the possibility to enhance the tuning range and functionality significantly by period length switching. Period length switching can be realized by employing two or more individually powerable subsets of superconducting coils and reverse the current in a part of the winding. So far, the first demonstration mock-up coil allowing period length tripling was fabricated and tested successfully (A. Grau et al., accepted for publication in IEEE Transactions on Applied Superconductivity). Here, we report on the feasibility of a superconducting switch implemented as proposed by A. Madur et al., Proc. of the 10th International Conference on Synchrotron Radiation Instrumentation 2009, Melbourne, Australia.
