Auf der Suche nach kosmischer Antimaterie

open access: yesPhysik in unserer Zeit, Volume 52, Issue 6, Page 274-281, November 2021., 2021
Im Mai 2011 wurde das Alpha Magnetic Spectrometer (AMS‐02) mit dem letzten Flug des Space‐Shuttles Endeavour auf die Internationale Raumstation gebracht. Seitdem erfasst es die geladene kosmische Strahlung mit bisher nie erreichter Präzision und liefert neue Einblicke in hochenergetische Prozesse in unserer Milchstraße.

Probing Compressed Baryonic Matter

open access: yesUniverse, 2022
The objective of the compressed baryonic matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt, Germany, is the investigation of the fundamental properties of strongly interacting matter.

Quantenlogik‐Uhren

open access: yesPhysik in unserer Zeit, Volume 52, Issue 4, Page 183-189, July 2021., 2021
Einige Atome sind durch Laserkühlung inzwischen so gut kontrollierbar, dass bereits optische Uhren mit Unsicherheiten im Bereich von 10–18 realisiert wurden. Vielen Atomen und den meisten Molekülen, die besonders empfindlich auf physikalische Effekte jenseits des Standardmodells reagieren, fehlt jedoch ein Übergang zum Laserkühlen.

Proposal of a New Double-Nozzle Technique for In-Gas-Jet Laser Resonance Ionization Spectroscopy

open access: yesAtoms, 2023
This paper proposes a new double-nozzle technique for in-gas-jet laser resonance ionization spectroscopy. We explored the functionality of this new technique through detailed gas dynamic and Monte Carlo atom-trajectory simulations, in which results are ...

Tank‐Circuit Assisted Coupling Method for Sympathetic Laser Cooling

open access: yesAdvanced Quantum Technologies, Volume 4, Issue 7, July 2021., 2021
A novel scheme is presented that allows to efficiently cool arbitrary ions by coupling them to a directly laser cooled ion in a separate Penning trap. The results demonstrate how a common tank circuit can drastically enhance the coupling, resulting in the expected avoided‐crossing behavior.

Measurement of Antiproton Production in p-He Collisions at sqrt[s_{NN}]=110  GeV. [PDF]

open access: yesPhysical Review Letters, 2018
The cross section for prompt antiproton production in collisions of protons with an energy of 6.5 TeV incident on helium nuclei at rest is measured with the LHCb experiment from a data set corresponding to an integrated luminosity of 0.5  nb^{-1}.

Properties of the quark‐gluon plasma created in heavy‐ion collisions

open access: yesAstronomische Nachrichten, Volume 342, Issue 5, Page 715-726, June 2021., 2021
Abstract We review the properties of the strongly interacting quark‐gluon plasma (QGP) at finite temperature and baryon chemical potential as created in heavy‐ion collisions at ultrarelativistic energies. The description of the strongly interacting (non‐perturbative) QGP in equilibrium is based on the effective propagators and couplings from the ...

Stability and lifetime study of carbon nanotubes as cold electron field emitters for electron cooling in the CERN extra low energy antiproton ring

open access: yesPhysical Review Accelerators and Beams, 2021
Electron cooling is a fundamental process to guarantee the beam quality in low energy antimatter facilities. In extra low energy antiproton, the electron cooler reduces the emittance blowup of the antiproton beam and thus delivers a focused and bright ...

Prospects for Low-Energy Antiproton Physics at Fermilab [PDF]

open access: yes, 2005
Fermilab has long had the world's most intense antiproton source. Despite this, opportunities for low-energy antiproton physics at Fermilab have in the past been limited and--with the antiproton source now exclusively dedicated to serving the needs of ...
