Multi-Reflection Time-of-Flight (MR-ToF) devices are powerful tools for high-precision mass spectrometry, highly selective and high-flux mass separation as well as, most recently, for highly sensitive laser spectroscopic applications. In this work, various ion-optical simulations are conducted to provide insights into optimizing the design of the MR-ToF apparatus to enhance performance across its diverse application fields. [...]

Isotopes at the limits of nuclear existence are of great interest for their critical role in nuclear astrophysical reactions and their exotic structure. Experimentally, exotic nuclides are challenging to address due to their low production cross-sections, overwhelming amounts of contamination, and lifetimes of typically less than a second. [...]

Charge radii of neutron-rich scandium isotopes and the seniority symmetry in the $0f_{7/2}$ shell
/ Bai, S.W. (Peking U., SKLNPT) ; Yang, X.F. (Peking U., SKLNPT) ; Koszorús, Á. (Leuven U.) ; Berengut, J.C. (New South Wales U.) ; Billowes, J. (Manchester U.) ; Bissell, M.L. (Manchester U.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Borschevsky, A. (Groningen U.) ; Campbell, P. (Manchester U.) ; Cheal, B. (Liverpool U.) et al.
Nuclear charge radii of neutron-rich $^{47-49}$Sc isotopes were measured using collinear laser spectroscopy at CERN-ISOLDE. The new data reveal that the charge radii of scandium isotopes exhibit a distinct trend between $N=20$ and $N=28$, with $^{41}$Sc and $^{49}$Sc isotopes having similar values, mirroring the closeness of the charge radii of $^{40}$Ca and $^{48}$Ca.

Creation and characterisation of multi-charged cerium beams at TRIUMF’s OLIS
/ Justus, P (U. Heidelberg (main) ; Heidelberg, Max Planck Inst.) ; Charles, C R J (TRIUMF ; Western Ontario U. ; Simon Fraser U.) ; Ames, F (TRIUMF) ; Jayamanna, K (TRIUMF) ; Malbrunot-Ettenauer, S (TRIUMF ; CERN)
A novel $^{140}$Ce$^{n+}$ stable ion beam was developed at TRIUMF’s Off-Line Ion Source (OLIS) facility for fundamental research into (i) astrophysical processes, and (ii) forming lanthanide molecules with O$_{2}$ gas and halogens. This first creation of a multi-charged $^{140}$Ce beam at OLIS is a successful chemical analog for actinide beams and molecule formation at TRIUMF’s TITAN facility for future electron dipole moment (EDM) measurements with rare radioactive thorium molecules..

Simulations of a cryogenic, buffer-gas filled Paul trap for low-emittance ion bunches
/ Lechner, S (CERN ; Vienna, Tech. U. ; McGill U.) ; Sels, S (CERN) ; Belosevic, I (TRIUMF) ; Buchinger, F (McGill U.) ; Fischer, P (Greifswald U.) ; Kanitz, C (Erlangen - Nuremberg U.) ; Lagaki, V (CERN ; Greifswald U.) ; Maier, F M (CERN ; Greifswald U.) ; Plattner, P (CERN ; Innsbruck U.) ; Schweikhard, L (Greifswald U.) et al.
Many experiments with pulsed ion beams benefit from or even require ion bunches with both small temporal width as well as small energy spread. To achieve optimal ion-beam preparation, a buffer-gas filled cryogenic Paul trap is being developed in the context of the Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS).
