Since formation in 2004, HTS-110 has developed a range of HTS magnets for magnetic x-ray experiments including high resolution diffraction, non-resonant magnetic scattering, resonant magnetic scattering, X-ray Magnetic Circular Dichroism (XMCD) spectroscopy and X-ray absorption spectroscopy and imaging, which are used worldwide in synchrotron research facilities such as BESSY (Germany), ALBA (Spain), NSLS-II (USA), APS (USA), Singapore Synchrotron Light Source (Singapore) and PAL (Korea).
