At the end of February the first of two transformer stations went into operation at the construction site of the future FAIR accelerator facility. It is the first system at FAIR to go into operation. The station provides the energy supply to the existing SIS18 ring accelerator and will also do so for the future SIS100 ring accelerator. The transformer station will supply the SIS18 particle accelerator with electricity as early as the experimentation phase scheduled to take place this summer.

Two transformers at FAIR’s North Transformer Station were recently switched through to GSI in order to supply parts of the facility with electricity. Until then, GSI had been supplied with power exclusively through the transformer station at Leonhardstanne. The new transformers will improve the performance of the pulse load supply, which will be needed in the future for the operation of the SIS18 and SIS100 particle accelerators.

The transformers were delivered to the FAIR construction site in the fall of 2017. They were then installed and have been put into operation as planned. The second transformer station, FAIR South, is expected to go into operation in the second quarter of 2018. The new transformers convert the 110 kV high-voltage electricity that arrives at GSI and FAIR through underground high-voltage cables to 20 kV so that the current reaches the various consumers on the campus in line with their needs.

The new transformer station will be needed for the facility’s next beam time, which is scheduled for the summer of 2018. In addition to the GSI accelerators UNILAC, SIS18, and ESR, as well as the current experiments, scientists will also be able to use components of FAIR, such as the CRYRING storage ring, for the planned FAIR Phase 0 experimentation program. The experiments using this beam time will involve scientists from all over the world.
