A linear radiofrequency quadrupole ion trap for the cooling and bunching of radioactive ion beams
A linear radio-frequency quadrupole ion guide and beam buncher has been installed at the ISOLTRAP mass spectrometry experiment at he ISOLDE facility at CERN. The apparatus is being used as a beam cooling, accumulation, and bunching system. It operates with a buffer gas that cools the injected ions and converts the quasicontinuous 60-keV beam from the ISOLDE facility to 2.5-keV beam pulses with improved normalized transverse emittance. Recent measurements suggest a capture efficiency of the ion guide of up to 40% and a cooling and bunching efficiency of at least 12% which is expected to still be increased. The improved ISOLTRAP setup has so far been very successfully in three on-line experiments. © 2002 Elsevier Science B.V. All rights reserved.
