000357192 520__ $$aDielectronic recombination (DR) is the resonant capture of a free electron by an ion. It is a fundamental process in determining the charge-state balance of low-temperature plasma environments, which can be found in a wide range of astrophysical objects such as planetary nebulae, active galactic nuclei and supernova remnants. Accurate rates of DR are therefore required to model these objects and correctly interpret astronomical observations. While theory can nowadays predict many DR transitions quite reliably, in particular for high centre-of-mass energies, transitions at low energies (ie a few eV and below) are less easy to predict in terms of their position and strength. In order to provide reliable data for plasma modelling, DR experiments are carried out at the electron coolers of heavy-ion storage rings which provide cooled merged-beam electron targets that allow for precise measurements of DR spectra. At the CRYRING@ESR storage ring at GSI/FAIR a new setup for DR measurements has been installed and taken into operation in the past few years. Making use of the ultra-cold electron beam and the wide variety of available ions in different charge states, we have implemented DR experiments to explore various physics cases. This includes both recombination rate measurements with an astrophysical motivation as described above, as well as the use of DR as a spectroscopic tool to probe the atomic structure of heavy highly-charged ions in order to benchmark atomic theory. The focus of this work is on DR measurements on neon ions: The first DR experiment conducted at CRYING@ESR was a test measurement on Li-like neon, which reproduced data obtained in a previous CRYRING experiment in Stockholm. As part of a new programme of astrophysically motivated DR campaigns, low-energy DR of O-like neon was then measured and the merged-beam recombination rate coefficient (MBRRC) and plasma recombination rate coefficient (PRRC) were calculated.
