The heavy ion trap facility (HITRAP), which is shown in fig.1 and is being built in the re-injection channel between ESR and SIS will provide unique beams of highly charged ions up to bare uranium at very low energies for a large variety of experiments. At the HITRAP facility the ions, produced by the GSI accelerator facility, will be decelerated in two(More)
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. For the first time the masses of the proton-unbound isotopes 144,145Ho and 147,148Tm were directly measured. The proton separation energies were derived from the measured mass values and(More)
The heavy ion trap facility (HITRAP), which is being built in the re-injection channel between ESR and SIS will provide unique beams of highly charged ions up to bare uranium at very low energies for a large variety of experiments. At the HITRAP facility it is envisaged to decelerate heavy highly charged ions down to energies of the keV-range where they can(More)
The electron beam ion source MAXEBIS, developed and built at the University of Frankfurt, has been installed at GSI to serve as an offline test ion source for the HITRAP project and for use as a test setup for charge breeding explorations. The setup has been equipped with new diagnostics and beam optics devices. Two ion sources dedicated to the production(More)
The heavy ion trap facility (HITRAP) (fig.1) will provide unique beams of highly charged ions up to bare U at very low energies for a large variety of experiments. HITRAP will decelerate ions (e.g. U 91+) produced by the GSI accelerator facility at relativistic energies. The ions are first decelerated the ESR down to 4 MeV/u and further decelerated down to(More)
Nuclides in the vicinity of 94Ag have been studied with the Penning trap mass spectrometer JYFLTRAP at the Ion-Guide Isotope Separator On-Line. The masses of the two-proton-decay daughter 92Rh and the beta-decay daughter 94Pd of the high-spin isomer in 94Ag have been measured, and the masses of 93Pd and 94Ag have been deduced. When combined with the data(More)
The masses of ten proton-rich nuclides, including the N=Z+1 nuclides ⁸⁵Mo and ⁸⁷Tc, were measured with the Penning trap mass spectrometer SHIPTRAP. Compared to the Atomic Mass Evaluation 2003 a systematic shift of the mass surface by up to 1.6 MeV is observed causing significant abundance changes of the ashes of astrophysical x-ray bursts. Surprisingly low(More)
