The PUMA offline ion source beamline
/ Schlaich, Moritz (Darmstadt, Tech. U.) ; Fischer, Paul (Greifswald U.) ; Giesel, Paul Florian (Greifswald U.) ; Klink, Clara (Darmstadt, Tech. U. ; CERN) ; Obertelli, Alexandre (Darmstadt, Tech. U.) ; Schweikhard, Lutz (Greifswald U.) ; Wienholtz, Frank (Darmstadt, Tech. U.)
The antiProton Unstable Matter Annihilation experiment (PUMA) at CERN aims to study the nucleonic composition in the matter density tail of stable and radioactive nuclei using low-energy antiprotons. Since there is no facility in which both low-energy antiprotons and radioactive nuclei can be produced, the experimental realization with exotic nuclei requires the transportation of the antiprotons from the Extra Low ENergy Antiproton (ELENA) facility to the nearby located Isotope mass Separator On-Line DEvice (ISOLDE).

Production and purification of molecular $^{225}$Ac at CERN-ISOLDE
/ Au, M (CERN ; U. Mainz, PRISMA) ; Nies, L (CERN ; Greifswald U.) ; Stegemann, S (CERN) ; Athanasakis-Kaklamanakis, M (CERN ; Leuven U. ; Imperial Coll., London) ; Cocolios, T E (CERN ; Leuven U.) ; Fischer, P (Greifswald U.) ; Giesel, P F (Greifswald U.) ; Johnson, J D (Leuven U.) ; Köster, U (CERN ; Laue-Langevin Inst.) ; Lange, D (Heidelberg, Max Planck Inst.) et al.
The radioactive nuclide $^{225}$Ac is one of the few promising candidates for cancer treatment by targeted-$\alpha$-therapy, but worldwide production of $^{225}$Ac faces significant limitations. In this work, the Isotope Separation On-Line method was used to produce actinium by irradiating targets made of uranium carbide and thorium carbide with 1.4-GeV protons. [...]

Development and commissioning of ion-optical elements for ion and antiproton beams with energies up to 5 keV
/ Klink, Clara (Darmstadt, Tech. U. ; CERN) ; Schlaich, Moritz (Darmstadt, Tech. U.) ; Fischer, Jonas (Darmstadt, Tech. U.) ; Obertelli, Alexandre (Darmstadt, Tech. U.) ; Schmidt, Alexander (Darmstadt, Tech. U.) ; Wienholtz, Frank (Darmstadt, Tech. U.)
In nuclear and atomic physics experiments, charged ion beams often need to be guided from the ion production to the experimental site. In the PUMA experiment, an ion source beamline was developed, which can be operated with up to \SI5{\kilo\electronvolt} beam energy at a base pressure of $10^{-9}$ mbar or better. [...]

Design and characterization of an antiproton deceleration beamline for the PUMA experiment
/ Fischer, Jonas (Darmstadt, Tech. U.) ; Schmidt, Alexander (Darmstadt, Tech. U.) ; Azaryan, Nikolay (CERN) ; Butin, François (CERN) ; Somoza, Jose Ferreira (CERN) ; Husson, Audric (Darmstadt, Tech.

We report on the design and characterization of an antiproton deceleration beamline, based on a pulsed drift tube, for the PUMA experiment at the Antimatter Factory at CERN. The design has been tailored to high-voltage (100 kV) and ultra-high vacuum (below $10^{-10}$ mbar) conditions. [...]

A multi-reflection time-of-flight mass spectrometer for the offline ion source of the PUMA experiment
/ Schlaich, M. (Darmstadt, Tech. Hochsch.) ; Fischer, J. (Darmstadt, Tech. Hochsch.) ; Fischer, P. (Greifswald U.) ; Klink, C. (Darmstadt, Tech. Hochsch.) ; Obertelli, A. (Darmstadt, Tech.

The antiProton Unstable Matter Annihilation experiment (PUMA) at CERN aims at investigating the nucleon composition in the matter density tail of radioactive as well as stable isotopes by use of low-energy antiproton-nucleon annihilation processes. For this purpose, antiprotons provided by the Extra Low ENergy Antiproton (ELENA) facility will be trapped together with the ions of interest. [...]

The use of radioactive molecules for fundamental physics research is a developing interdisciplinary field limited dominantly by their scarce availability. In this work, radioactive molecular ion beams containing actinide nuclei extracted from uranium carbide targets are produced via the Isotope Separation On-Line technique at the CERN-ISOLDE facility.
