Manas Mukherjee,Dietrich Beck,Klaus Blaum,Georg Bollen,Jens Dilling,Sebastian George,F. Herfurth,Alexander Herlert,Alban Kellerbauer,H.-J. Kluge,Stefan Schwarz,Lutz Schweikhard,C. Yazidjian +12 more
TL;DR: ISOLTRAP as discussed by the authors is a Penning trap mass spectrometer for high-precision mass measurements on short-lived nuclides installed at the on-line isotope separator ISOLDE at CERN.

Sebastian George,Klaus Blaum,F. Herfurth,Alexander Herlert,Martin Kretzschmar,Szilard Nagy,Stefan Schwarz,Lutz Schweikhard,C. Yazidjian +8 more
TL;DR: In this paper, a new excitation scheme, Ramsey's method of time-separated oscillatory fields, has been successfully tested with the ISOLTRAP mass spectrometer at ISOLDE/CERN for mass measurements on stable as well as short-lived nuclides.
Journal ArticleDOI

TL;DR: It is shown that the Ramsey method applied to Penning trap mass measurements yields a statistical uncertainty similar to that obtained by the conventional technique but 10 times faster, which is a new powerful tool for high-precision mass measurements.

TL;DR: In this article, the authors proposed a method for high-accuracy mass measurements of the shortest-lived isotopes and decay studies at the FAIR facility using an electron beam ion trap for charge breeding, ion traps for beam preparation, and a high-precision Penning trap system for mass measurements and decay analysis.
