Laser systems with intensities of the order of 1020 W/cm2 have electric fields that are similar to the electric fields in highly-charged ions which makes them interesting targets for laser experiments. HILITE (High Intensity Laser Ion Trap Experiment) supplies an ion target designed for the particular needs at different laser facilities.
To provide a well defined ion cloud, the ions should be as cool as possible. A common way to cool them to sub-meV energies is resistive cooling. A coil is connected in parallel to an electrode into which moving ions induce a current. When the motion frequency of the ions matches the resonance frequency of the resonator, this current is amplified resonantly, enabling efficient non-destructive detection. In resonance the ions transfer their energy to the resonantor and hence are cooled.
In order to increase the resonator’s quality factor, a superconducting NbTi wire is used for the coil. We will present the assembly, properties and characterization measurements of the axial resonator.
