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. U.) ; Klink, Clara (CERN) ; Obertelli, Alexandre (Darmstadt, Tech. U.) ; Schlaich, Moritz (Darmstadt, Tech. U.) ; Sinturel, Alexandre (CERN) et al.
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. [...]
