CRYRING@ESR is the first operational heavy ion storage ring of the FAIR project (Facility for Antiproton and Ion Research) . It has a long history of successful research in atomic and molecular physics during its two-decade operation as a central research facility of the Manne Siegbahn Laboratory in Stockholm, Sweden. After its shutdown it was decided to transfer CRYRING to FAIR/GSI as a Swedish in-kind contribution to the FAIR project. Starting in 2015 it was modernized, adapted to FAIR standards and connected to the existing experimental storage ring ESR under the project name CRYRING@ESR. In 2017 first ions from a local ion source could be stored and in the end of 2019 first ions from ESR were successfully transferred and stored in CRYRING@ESR. Despite the difficult situation due to SARS-CoV-2 in spring this year a reduced physics program during the GSI beam time block could be performed. For the next two years approx. 400 8-hour shifts are foreseen for experiments at ESR and CRYRING. A call for beam time proposals just ended a few days ago and a large number of applications is expected.
In this seminar I will present the status of CRYRING@ESR and give an overview of the foreseen physics program together with results from the first successful experiments.
