“…At the IGISOL facility, radioactive ion beams are produced using the ion-guide method with thin foil targets. Various offline sources are available to provide stable ion beams, such as a spark discharge source which was used in this work [4]. After production, beams are mass separated using a dipole magnet, with a typical mass resolving power of about 400, and injected into the radiofrequency quadrupole (RFQ) cooler-buncher.…”

Collinear laser spectroscopy of stable palladium isotopes at the IGISOL facility

et al. 2020

Collinear laser spectroscopy on stable palladium isotopes was performed at the IGISOL facility in Jyväskylä in preparation for an experiment on its neutron-rich isotopes. Five transitions from different initial atomic states were tested, with the goal of finding the most spectroscopically efficient. The observed intensities afforded a comparison with atomiclevel population predictions based on charge-exchange calculations. For some transitions hyperfine parameters of 105 Pd were measured, which were found to be in good agreement with literature values. A King plot analysis was performed using the measured isotope shifts and known charge radii from literature to determine the atomic field and mass shift factors.

“…However, obtaining the reference as a by-product of fission entails a risk of misidentifying it for another species or molecule with nearly equal mass. In order to eliminate this risk, an offline ion source station [51], completely separate from the IGISOL target chamber, was later added to the beam line. The stable 133 Cs + reference ions were produced at this offline station.…”

“…The new off-line ion source station [51] consists of multiple ion sources and a beamline that connects to the existing IGISOL beamline just before the IGISOL dipole magnet. A deflector allows for rapid switching between the off-line ion beams and the radioactive ion beams from the IGISOL target chamber.…”

The JYFLTRAP double Penning trap at the Ion Guide Isotope Separator On-Line (IGISOL) facility has been used to measure the atomic masses of 13 neutron-rich rare-earth isotopes. Eight of the nuclides, 161 Pm, 163 Sm, 164,165 Eu, 167 Gd, and 165,167,168 Tb, were measured for the first time. The systematics of the mass surface has been studied via one-and two-neutron separation energies as well as neutron pairing-gap and shell-gap energies. The proton-neutron pairing strength has also been investigated. The impact of the new mass values on the astrophysical rapid neutron capture process has been studied. The calculated abundance distribution results in a better agreement with the solar abundance pattern near the top of the rare-earth abundance peak at around A ≈ 165.

“…The continuous radioactive ion beam from IGISOL is first mass-separated using a dipole magnet, which is usually sufficient to select the mass number of interest A. In addition to IGISOL, ion beams can be delivered from an offline ion source station [10], housing an electric discharge ion source and a surface ion source. There is also a space reservation for a laser ablation ion source.…”

Recent experiments at the JYFLTRAP Penning trap

View full text Add to dashboard Cite

The JYFLTRAP double Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility offers excellent possibilities for high-precision mass measurements of radioactive ions. Around 400 atomic masses, including around 50 isomeric states, have been measured since JYFLTRAP became operational. JYFLTRAP has also been used as a high-resolution mass separator for decay spectroscopy experiments as well as an ion counter for fission yield studies. In this contribution, an overview of recent activities at the JYFLTRAP Penning trap is given, with a focus on nuclei discussed in the PLATAN2019 meeting.
