The SPARC EBIT at GSI / FAIR is used as an offline injector for the low energy beamline section of the HITRAP project. In this way, the HITRAP beamline can be comissioned and experiments can be conducted independent from the beam of GSI / FAIR's accelerator complex where beam time is rare.
A Test Ion Source and Offline-Injector for the HITRAP project at GSI / FAIR
"A beamline for transport of highly charged ions with energies as low as a few keV/charge has been constructed and commissioned at GSI. Complementary to the existing infrastructure of the HITRAP facility for deceleration of highly charged ions from the GSI accelerator, the new beamline connects the HITRAP ion decelerator and an [Dresden] EBIT with the associated experimental setups. Therefore, the facility can now transport the decelerated heavy highly charged ions to the experiments or supply them offline with medium-heavy highly charged ions from the [Dresden] EBIT, both at energies as low as a few keV/charge."
