Systems provided by German UPS manufacturer Piller are to help support operations at Sweden’s MAX IV electron accelerator research laboratory in Lund.
Piller said its 7.5MVA medium voltage rotary UPS— expandable to 12.5MVA and which features kinetic energy storage— will help protect the facility’s “highly sensitive and sophisticated research equipment”.
Jacob Schuster, project coordinator at Lund University MAX IV, said: “The MAX IV accelerator is very sensitive to variations in power supply, and the extremely short disturbances that arise from the external power grid currently result in several reboots of the plant every week.
“Electrons are the source of the intense X-rays used for the experiments at our experimental stations,” Schuster said. “Producing these and then controlling them at the speed of light is a complex process that places high demands on the plant and the associated infrastructure.”
“As a consequence of the interference on the power grid, research teams with limited access to the experimental stations may lose valuable time, so we are keen that the power supply to MAX IV is of very high quality,” Schuster added.
The critical power system will be installed by Malmö-based construction firm APQ El.
