Abstract.

An ion beam cooler has been constructed to adapt the emittance of the ISOLDE rare isotope beam to the acceptance of the mass spectrometer MISTRAL at CERN. Using 20,22Ne+ beams with an energy of Ebeam = 45 keV the transmission through the cooler was measured to be T = 0.25. An analytical model to describe the transmission as a function of the trapping potential is discussed. By fitting this model to the data, the lateral energy distribution of the radially confined ions was determined to be centered at E0 = 1.3(1) eV and to have a width of σE = 1.6(1) eV.
