A new cooling technique for heavy ions in a Penning trap
G. Savard,St. Becker,G. Bollen,H.-J. Kluge,R.B. Moore,R.B. Moore,T. Otto,Lutz Schweikhard,H. Stolzenberg,U. Wiess +9 more
TL;DR: In this paper, a new cooling technique for heavy ions stored in a Penning trap was developed, where axial and cyclotron motions were cooled by buffer gas collisions, and the outward radial diffusion caused by the buffer gas was counteracted by an azimuthal quadrupole rf field.
Journal ArticleDOI

Lunney,Vladimir Manea,Javier Fernandez Menendez,D. Neidherr,Marco Rosenbusch,Lutz Schweikhard,Achim Schwenk,J. Simonis,J. Stanja,Robert Wolf,Kai Zuber +23 more
TL;DR: The mass determination of the exotic calcium isotopes 53Ca and 54Ca is reported, using the multi-reflection time-of-flight mass spectrometer of ISOLTRAP at CERN, to establish a prominent shell closure at neutron number N = 32, in excellent agreement with the theoretical calculations.
Journal ArticleDOI
First Penning Trap Mass Measurements beyond the Proton Drip Line
C. Rauth,Dieter Ackermann,Klaus Blaum,Michael Block,A. Chaudhuri,Z. Di,Sergey Eliseev,Rafael Ferrer,D. Habs,Frank Herfurth,F. P. Heßberger,Sigurd Hofmann,Hans-Jürgen Kluge,G. Maero,A. Martín,Gerrit Marx,Manas Mukherjee,J. Neumayr,W. R. Plaß,S. Rahaman,Daniel Rodriguez Rodriguez,C. Scheidenberger,Lutz Schweikhard,P. G. Thirolf,G. Vorobjev,C. Weber +25 more
TL;DR: The masses of six neutron-deficient rare holmium and thulium isotopes close to the proton drip line were determined with the SHIPTRAP Penning trap mass spectrometer with new proton separation energies derived from the measured mass values and compared to predictions from mass formulas.
Journal ArticleDOI
ISOLTRAP: a tandem Penning trap system for accurate on-line mass determination of short-lived isotopes
G Bollen,St. Becker,Hans-Jürgen Kluge,M. König,R. B. Moore,T Otto,T Otto,H. Raimbault-Hartmann,H. Raimbault-Hartmann,G Savard,G Savard,Lutz Schweikhard,H. Stolzenberg +12 more
TL;DR: The tandem Penning trap mass spectrometer ISOLTRAP has been set up at the on-line mass separator ISOLDE at CERN/Geneva for accurate mass measurements of short-lived nuclei with T 1 2 ≥ 1 s.
Journal ArticleDOI

Alban Kellerbauer,Klaus Blaum,Georg Bollen,Frank Herfurth,H.-J. Kluge,M. Kuckein,E. Sauvan,C. Scheidenberger,Lutz Schweikhard +8 more
TL;DR: In this paper, a detailed study of the accuracy of the Penning trap mass spectrometer ISOLTRAP all expected sources of uncertainty were investigated with respect to their contributions to the uncertainty of the final result.
