MAXIV is a Swedish national laboratory at the University of Lund. It is a strategic partner of the SOLARIS Centre. Swedish scientists provided the Poles with a synchrotron design based on the unique technology of integrated magnets – the SOLARIS synchrotron is a replica of one of the two light sources in Lund. Since 2010, the Polish and Swedish team have worked closely together, sharing their knowledge and experience: initially in the field of building synchrotrons, and now as regards their operation.
