ISOLTRAP
ISOLTRAP is a tandem Penning trap mass spectrometer at the On-Line Isotope Mass Separator at CERN, very similar to SMILETRAP. The facility plays a leading role in the field of high precision mass spectrometry of radioactive ions. The masses of more than 200 short-lived nuclides have been measured with a relative uncertainty of typically dm/m ~ 1x10-7 and even almost up to one order of magnitude lower in some special cases.
