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 DR measurements were performed at the CRYRING@ESR electron cooler and we will present the newly established particle detection and data acquisition setup and the results of DR measurements of astrophysically relevant neon ions in low charge states. A test run in May 2020 with Ne7+ from an ECR source was used to commission the setup and study electron beam temperatures. It demonstrated an undegraded resolution compared to previous measurements. It was followed up in May 2021 by a scheduled experiment on astrophysically relevant low-energy DR of Ne2+.
