SHIRaC : an RFQ Cooler for high-intensity beams

Future RIB facilities like Spiral2 will push the limits of production with higher intensities and more exotic beams. However, to achieve better experimental sensitivities and accuracies, a mass resolution of m/Δm ~ few 104 is necessary to separate the ions of interest and their isobaric contaminants. At an energy of few tens of keV, the purification is obtained by the use of an High Resolution Separator (HRS). The employment of gas-filled linear Paul traps, the so-called radiofrequency cooler, is required to reach the needed performances of the magnetic device by the reduction of the beam emittance.
