  • Constraints on the Coupling between Axionlike Dark Matter and Photons Using an Antiproton Superconducting Tuned Detection Circuit in a Cryogenic Penning Trap 
    Devlin, Jack A.; Borchert, Matthias J.; Erlewein, Stefan; Fleck, Markus; Harrington, James A.; Latacz, Barbara; Warncke, Jan; Wursten, Elise; Bohman, Matthew A.; Mooser, Andreas H.; Smorra, Christian; Wiesinger, Markus; Will, Christian; Blaum, Klaus; Matsuda, Yasuyuki; Ospelkaus, Christian; Quint, Wolfgang; Walz, Jochen; Yamazaki, Yasunori; Ulmer, Stefan (College Park, Md. : APS, 2021)
    We constrain the coupling between axionlike particles (ALPs) and photons, measured with the superconducting resonant detection circuit of a cryogenic Penning trap. By searching the noise spectrum of our fixed-frequency ...
  • Cryogenic linear Paul trap for cold highly charged ion experiments 
    Schwarz, M.; Versolato, O.O.; Windberger, A.; Brunner, F.R.; Ballance, T.; Eberle, S.N.; Ullrich, J.; Schmidt, Piet O.; Hansen, A.K.; Gingell, A.D.; Drewsen, M.; Crespo López-Urrutia, J.R. (College Park, MD : American Institute of Physics, 2012)
    Storage and cooling of highly charged ions require ultra-high vacuum levels obtainable by means of cryogenic methods. We have developed a linear Paul trap operating at 4 K capable of very long ion storage times of about ...
  • A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions 
    Leopold, T.; King, S.A.; Micke, P.; Bautista-Salvador, A.; Heip, J.C.; Ospelkaus, C.; Crespo López-Urrutia, J.R.; Schmidt, P.O. ([Erscheinungsort nicht ermittelbar] : American Institute of Physics, 2019)
    A cryogenic radio-frequency ion trap system designed for quantum logic spectroscopy of highly charged ions (HCI) is presented. It includes a segmented linear Paul trap, an in-vacuum imaging lens, and a helical resonator. ...
  • In Situ X-Ray Diffraction Analysis of Microstructure Evolution during Deep Cryogenic Treatment and Tempering of Tool Steels 
    Cui, Chengsong; Dong, Juan; Epp, Jérémy; Schulz, Alwin; Steinbacher, Matthias; Acar, Serdal; Herbst, Sebastian; Maier, Hans Jürgen (Weinheim : Wiley-VCH, 2021)
    Deep cryogenic treatment of tool steels, incorporated in conventional hardening and tempering, has been a topic of intensive research in recent years. Yet, the governing microstructural mechanisms involved in the deep ...
  • 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 ...
  • MetroMMC: Electron-Capture Spectrometry with Cryogenic Calorimeters for Science and Technology 
    Ranitzsch, P.C.-O.; Arnold, D.; Beyer, J.; Bockhorn, L.; Bonaparte, J.J.; Enss, C.; Kossert, K.; Kempf, S.; Loidl, M.; Mariam, R.; Nähle, O.J.; Paulsen, M.; Rodrigues, M.; Wegner, M. (Heidelberg : Springer Verlag, 2019)
    Accurate decay data of radionuclides are necessary for many fields of science and technology, ranging from medicine and particle physics to metrology. However, data that are in use today are mostly based on measurements ...
  • Modelling and designing cryogenic hydrogen tanks for future aircraft applications 
    Winnefeld, Christopher; Kadyk, Thomas; Bensmann, Boris; Krewer, Ulrike; Hanke-Rauschenbach, Richard (Basel : MDPI AG, 2018)
    In the near future, the challenges to reduce the economic and social dependency on fossil fuels must be faced increasingly. A sustainable and efficient energy supply based on renewable energies enables large-scale applications ...
