Integrating UHV (ultra high vacuum) and HTS (High Temperature Superconducting) magnets for X-ray synchrotron based experiments

Abstract

Integrating UHV (ultra high vacuum) and superconducting magnets poses special challenges to the magnet designer. A range of HTS (High Temperature Superconducting) magnets have been developed for UHV synchrotron beamline applications providing users with compact powerful cryogen-free solutions. Recent examples include HTS magnets for LARIAT (Large Area Rapid Imaging Analytical Tool) [8.5 T with 110 mm warm bore], X-ray scattering experiments at BESSY and LNLS [5-6 T with 110 degrees scattering angle aperture], X-ray magnetic circular dichroism, and resonant scattering experiments at ALBA. This paper will focus on the in-UHV HTS magnet installed at ALBA. © Published under licence by IOP Publishing Ltd.
