NSLS-II Colloquium Series

"Development of insertion devices at SOLEIL"

Presented by Marie Emmanuelle Couprie, SOLEIL, France

Thursday, January 11, 2018, 4:00 pm — Large Seminar Room, Bldg. 510

Insertion devices (undulators and wigglers) are essential components for accelerator based light sources, such as synchrotron radiation facilities implemented on storage rings and free electron lasers. The wide panoply of insertion devices developed at Synchrotron SOLEIL (electromagnetic, combined permanent magnet and electromagnetic for rapid switching of the polarization, permanent magnet APPLE-II, hybrid in-vacuum and cryogenic undulators, out and in-vacuum wigglers) enables to cover a very wide spectral range (from the UV to the hard X-rays), and to provide flexibility for the users of the SOLEIL third generation light source. Starting from the description of the developments carried out at SOLEIL on the different types of systems, some future perspectives will be given, considering the evolution of the specifications of the different light source types. The use of the undulator radiation for photon beam based alignment and adjustment (such as taper) will be discussed. Furthermore, undulator radiation can serve as an electron beam diagnostic and provide a further insight on the electron beam quality itself, as illustrated in the case of the COXINEL project, using laser plasma acceleration.
