After its move from Stockholm to GSI, CRYRING@ESR is now back in operation with previously inaccessible ion species available from the accelerator complex as well as a smaller selection from a local injector. The first merged-beam measurements of dielectronic recombination (DR) were performed at the CRYRING@ESR electron cooler since its move from Stockholm using a newly established particle detection and data acquisition setup. We present results from a scheduled experiment on low-energy DR of Ne2+ in May 2021. Neon is an astrophysically abundant element and absolute DR rates for low charge states are important for the modelling of cold, photoionized plasmas such as planetary nebulas. We plan to continue our DR experiments with a series of other low charge state ions which are of key importance for the quantitative analysis of astrophysical data.
