	High precision tests of fundamental theories can often unfold their full potential only by using highly charged ions (HCI) at very low energies. Although in light of the envisaged energies at FAIR, experiments in the keV to MeV range may sound like backpedaling, these two techniques are in fact complementary, since the production of heavy HCI is virtually impossible without prior acceleration and electron stripping. However, subsequent preparation, transport, storage and detection of low-energy HCI bring new, surprising sets of problems and limitations. Here we will give an overview of the CRYRING@ESR local injector and the HITRAP linear decelerator. These two facilities consist out of one or two accelerator or decelerator stages, with a total length of around 10 meters, making them "compact" in comparison to other GSI accelerators.

High precision tests of fundamental theories can often unfold their full potential only by using highly charged ions (HCI) at very low energies. Although in light of the envisaged energies at FAIR, experiments in the keV to MeV range may sound like backpedaling, these two techniques are in fact complementary, since the production of heavy HCI is virtually impossible without prior acceleration and electron stripping. However, subsequent preparation, transport, storage and detection of low-energy HCI bring new, surprising sets of problems and limitations. Here we will give an overview of the CRYRING@ESR local injector and the HITRAP linear decelerator. These two facilities consist out of one or two accelerator or decelerator stages, with a total length of around 10 meters, making them "compact" in comparison to other GSI accelerators. The following sections describe their main design parameters, the achieved ion numbers, challenges of beam detection, as well as some special features such as multi-turn injection and single-shot energy analyzers. The conclusion will present the current status and will also give an outlook of the planned applications of low-energy ions at the FAIR facility.
