If you fly over MAX IV right now and look down, you’ll see a large circular building. The reason for this size and shape is the 528-meter-long 3GeV storage ring which precisely guides bunches of electrons traveling at velocities approaching the speed of light. As the electrons pass through arrays of magnets called insertion devices, they produce bright X-rays which are then used by beamline scientists to do many different types of experiments.
In an article published this month in the Journal of Synchrotron Radiation, the 3 GeV ring team led by Pedro Tavares describe the results for the first year of operation. This important milestone in the MAX IV project provides validation for many of the brand-new concepts that were implemented in the MAX IV design in order to improve the performance of the machine and reduce downtime.
