Accelerator in operation — FAIR Phase 0 experiments underway

09.02.2021

Today, the GSI/FAIR accelerator facilities successfully started a new operating phase to conduct scientific experiments of the FAIR Phase 0 program. From February to July, scientists from all over the world will investigate numerous research questions in the fields of nuclear physics, atomic physics, biophysics, materials research and plasma physics in the framework of approximately 80 approved experiments. We look forward to a rich harvest of scientific results.

The complete accelerator facility will be in operation: the linear accelerator UNILAC, the ring accelerator SIS18, the experimental storage ring ESR, the fragment separator FRS, the high-power laser PHELIX and, for the first time, the new FAIR storage ring CRYRING will be available for use by the researchers. A large number of experimental sites will be served, partly in parallel operation, with different ion beams from hydrogen to uranium. The science run at the GSI facilities is part of the FAIR experimental program, the so-called FAIR Phase 0, which already offers excellent experimental opportunities while FAIR is still under construction.

During the previous shutdown, numerous maintenance and modernization measures could be implemented to further prepare the existing facility for future operation as a pre-accelerator of the FAIR facility. Due to the Corona pandemic, the usual travel of domestic and foreign guest scientists remains limited during this experiment period. However, the shutdown was also used to expand remote access to parts of the facility for the researchers and improve electronic communication in order to enable the best possible performance of the scientific work.
