A super electron beam ion trap has been used to produce bare U92+ ions at an electron beam energy of 198 keV. Evaporative cooling with light ions was used to trap a population of 5×104 highly charged uranium ions for many seconds and reduce their temperature to less than 2q eV, suggesting that a very low emittance source of these ions is possible. Roughly 10 U92+ and 500 U91+ ions were present in the Super electron beam ion trap as determined from x‐ray emission spectra of the trapped ions. © 1996 American Institute of Physics.
