The BL29 (BOREAS), Resonant Absorption and Scatering,is a soft X-ray beamline with a helical undulator to produce variable-polarization light. The first experimental end-station is dedicated to X-ray magnetic circular dichroism (XMCD) and X-ray magnetic linear dichroism (XMLD) techniques,for studies of advanced magnetic materials. It allows applied magnetic fields of up to 6 Tesla, sample temperatures in a range 2-400 K, and electrical contacts for variable voltage biasing of samples.

The second experimental end-station is dedicated to soft X-ray magnetic scattering (SXRS). This instrument is based on an ultra-high vacuum reflectometerand allow applied magnetic fields up to 2 Tesla and temperatures of 20-400K.
