  • 350-fold improved measurement of the antiproton magnetic moment using a multi-trap method 
    Smorra, Christian; Blessing, Pascal E.; Borchert, Matthias J.; Devlin, Jack A.; Harrington, James A.; Higuchi, Takashi; Morgner, Jonathan; Nagahama, Hiroki; Sellner, Stefan; Bohman, Matthew A.; Mooser, Andreas H.; Schneider, Georg L.; Schön, Natalie; Wiesinger, Markus; Blaum, Klaus; Matsuda, Yasuyuki; Ospelkaus, Christian; Quint, Wolfgang; Walz, Jochen; Yamazaki, Yasunori; Ulmer, Stefan (New York, NY : Springer International Publishing, 2018)
    We summarize our recent 1.5 parts per billion measurement of the antiproton magnetic moment using the multi Penning-trap system of the BASE collaboration. The result was achieved by combining the detection of individual ...
  • Challenging the Standard Model by high precision comparisons of the fundamental properties of antiprotons and protons 
    Borchert, Matthias Joachim (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    This thesis describes high precision measurements on the fundamental properties of the antiproton, namely the charge-to-mass ratio and the magnetic moment. This work is embedded in the experimental work of the BASE ...
  • Cryogenic 9Be+ Penning trap for precision measurements with (anti-)protons 
    Niemann, M.; Meiners, T.; Mielke, J.; Borchert, M.J.; Cornejo, J.M.; Ulmer, S.; Ospelkaus, C. (Bristol : Institute of Physics Publishing, 2019)
    Cooling and detection schemes using laser cooling and methods of quantum logic can contribute to high precision CPT symmetry tests in the baryonic sector. This work introduces an experiment to sympathetically cool protons ...
  • Design and commissioning of an experiment for sympathetic cooling and coupling of ions in a cryogenic Penning trap 
    Niemann, Malte (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Precise comparisons between the properties of matter and antimatter conjugates constitute a stringent test of CPT and Lorentz symmetries. The proton’s and antiproton’s magnetic moments have recently been measured to high ...
  • Improved limit on the directly measured antiproton lifetime 
    Sellner, S.; Besirli, M.; Bohman, M.; Borchert, M.J.; Harrington, J.; Higuchi, T.; Mooser, A.; Nagahama, H.; Schneider, G.; Smorra, C.; Tanaka, T.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (Bristol : Institute of Physics Publishing, 2017)
    Continuous monitoring of a cloud of antiprotons stored in a Penning trap for 405 days enables us to set an improved limit on the directly measured antiproton lifetime. From our measurements we extract a storage time of ...
  • Measurement of Ultralow Heating Rates of a Single Antiproton in a Cryogenic Penning Trap 
    Borchert, M.J.; Blessing, P.E.; Devlin, J.A.; Harrington, J.A.; Higuchi, T.; Morgner, J.; Smorra, C.; Wursten, E.; Bohman, M.; Wiesinger, M.; Mooser, A.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (College Park, MD : American Physical Society, 2019)
    We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron quantum transition rates of 6(1) quanta/h ...
  • Superconducting Solenoid System with Adjustable Shielding Factor for Precision Measurements of the Properties of the Antiproton 
    Devlin, Jack A.; Wursten, Elise; Harrington, James A.; Higuchi, Takashi; Blessing, Pascal E.; Borchert, Matthias J.; Erlewein, Stefan; Hansen, Jannek J.; Morgner, Jonathan; Bohman, Matthew A.; Mooser, Andreas H.; Smorra, Christian; Wiesinger, Markus; Blaum, Klaus; Matsuda, Yasuyuki; Ospelkaus, Christian; Quint, Wolfgang; Walz, Jochen; Yamazaki, Yasunori; Ulmer, Stefan (College Park, Md. [u.a.] : American Physical Society, 2019)
    A superconducting self-shielding three-solenoid system with an adjustable shielding factor is developed, implemented, and characterized using a single antiproton in a Penning trap. With the tuned system, we suppress external ...
  • Sympathetic cooling schemes for separately trapped ions coupled via image currents 
    Will, C.; Bohman, M.; Driscoll, T.; Wiesinger, M.; Abbass, F.; Borchert, M.J.; Devlin, J.A.; Erlewein, S.; Fleck, M.; Latacz, B.; Moller, R.; Mooser, A.; Popper, D.; Wursten, E.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Smorra, C.; Ulmer, S. ([Bad Honnef] : Dt. Physikalische Ges., 2022)
    Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transitions for direct laser cooling. We study ...
  • The TRAPSENSOR facility: An open-ring 7 tesla Penning trap for laser-based precision experiments 
    Gutiérrez, Manuel J.; Berrocal, Joaquín; Cornejo, Juan M.; Domínguez, Francisco; Del Pozo, Jesús J.; Arrazola, Iñigo; Bañuelos, Javier; Escobedo, Pablo; Kaleja, Oliver; Lamata, Lucas; Rica, Raúl A.; Schmidt, Stefan; Block, Michael; Solano, Enrique; Rodríguez, Daniel (Bristol : Institute of Physics Publishing, 2019)
    A Penning-trap facility for high-precision mass spectrometry based on a novel detection method has been built. This method consists in measuring motional frequencies of singly-charged ions trapped in strong magnetic fields ...
