/ 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).

/ Lechner, S. (CERN ; Vienna, Tech. U., Atominst.) ; Miyagi, T. (Darmstadt, EMMI ; Heidelberg, Max Planck Inst. ; TRIUMF) ; Xu, Z.Y. (Leuven U. ; Tennessee U.) ; Bissell, M.L.

(CERN ; Heidelberg, Max Planck Inst.) et al.
Nuclear moments of the antimony isotopes $^{113-133}$Sb are measured by collinear laser spectroscopy and used to benchmark phenomenological shell-model and \textit{ab initio} calculations in the valence-space in-medium similarity renormalization group (VS-IMSRG). The shell-model calculations reproduce the electromagnetic moments over all Sb isotopes when suitable effective $g$-factors and charges are employed. [...]

Collinear laser spectroscopy was performed on the isomer of the aluminium isotope $^{26m}$Al. The measured isotope shift to $^{27}$Al in the $3s^{2}3p\;^{2}\!P^\circ_{3/2} \rightarrow 3s^{2}4s\;^{2}\!S_{1/2}$ atomic transition enabled the first experimental determination of the nuclear charge radius of $^{26m}$Al, resulting in $R_c$=\qty{3.130±.015}{\femto\meter}.

Simulation studies of a 30-keV MR-ToF device for highly sensitive collinear laser spectroscopy
/ Maier, F M (CERN ; Greifswald U.) ; Vilen, M (CERN) ; Belosevic, I (TRIUMF) ; Buchinger, F (McGill U.) ; Kanitz, C (CERN ; Erlangen - Nuremberg U.) ; Lechner, S (CERN ; McGill U.) ; Leistenschneider, E (CERN) ; Nörtershäuser, W (Darmstadt, Tech.

The Multi Ion Reflection Apparatus for Collinear Laser Spectroscopy (MIRACLS) seeks to extend the reach of high-resolution collinear laser spectroscopy (CLS) to more exotic radionuclides. In this novel technique, ion bunches of short-lived radioisotopes are trapped between two electrostatic mirrors of a Multi-Reflection Time-of-Flight (MR-ToF) device at 30-keV kinetic energy. [...]

Doppler and sympathetic cooling for the investigation of short-lived radioactive ions
/ Sels, S (CERN ; Leuven U.) ; Maier, F M (CERN ; Greifswald U.) ; Au, M (CERN ; Mainz U.) ; Fischer, P (Greifswald U.) ; Kanitz, C (CERN) ; Lagaki, V (CERN ; Greifswald U.) ; Lechner, S (CERN ; TU Vienna) ; Leistenschneider, E (CERN) ; Leimbach, D (CERN ; Mainz U., Inst. Phys. ; U. Gothenburg (main)) ; Lykiardopoulou, E M (British Columbia U. ; TRIUMF) et al.
At radioactive ion beam (RIB) facilities, ions of short-lived radionuclides are cooled and bunched in buffergas-filled Paul traps to improve the ion-beam quality for subsequent experiments. To deliver even colder ions, beneficial to RIB experiments’ sensitivity or accuracy, we employ Doppler and sympathetic cooling in a Paul trap cooler-buncher. [...]

Stray-light Suppression for the MIRACLS Proof-of-principle Experiment

U.) et al.
The Multi-Ion Reflection Apparatus for Collinear Laser Spectroscopy
(MIRACLS), currently under development at ISOLDE/CERN, aims to
combine the high resolution of fluorescence-based collinear laser spectroscopy (CLS) with a high sensitivity. This will be achieved by confining
30-keV ion bunches in a Multi-Reflection Time-of-Flight (MR-ToF) device
which allows laser spectroscopic probing for several thousand times. [...]
