RF Wien Filter

JEDI

The JEDI (Jülich Electric Dipole moment Investigations) collaboration was created in the end of 2011. It is aiming to carry out a long term project for the measurement of permanent electic dipole moments of charged particles in storage rings. The picture on the left shows the RF (radio frequency) Wien filter, which will be used for first measurement at COSY, installed in the COSY ring. More: JEDI …

Neutrinophysik

Die durch die Rekrutierungsinitiative der Helmholtz-Gemeinschaft gegründete Neutrinogruppe des IKP-2 beschäftigt sich mit Niederenergieneutrinophysik in Flüssigszintillator-Detektoren. More: Neutrinophysik …

TRIC

Time Reversal Invariance at COSY (TRIC)

The TRIC project was initiated as one of the first attempts to test a fundamental symmetry at COSY. The project aims to improve the present upper limit on T-symmetry violation in the hadronic sector by at least one order of magnitude. The violation of T-symmetry is needed to explain one of the fundamental problems of the Standard Model - the Baryon Asymmetry of the Universe: where is the antimatter?

Deuteron Source

Polarized Fusion

Since 50 years it is undisputed that the energy production of a coming fusion reactor for the DT or the D3He reaction is increased when the nuclear fuel will be polarized. But before this option can be used a bunch of questions must be answered. More: Polarized Fusion …

ANKE 2014

ANKE

The ANKE facility (Apparatus for Studies of Nucleon and Kaon Ejectiles) is a large acceptance forward magnetic spectrometer which was in operation at an internal target station in the COSY ring since 1998. The experimental hadron physics program at ANKE-COSY has been completed at the end of 2014. More: ANKE …

WASA-at-COSY

WASA-at-COSY

WASA, a spectrometer with large solid angle acceptance, has been operated at the internal COSY beam from 2006 to 2015. It was used to investigate the production and decay of light mesons and to study symmetries and symmetry breaking patterns. More: WASA-at-COSY …

PAX Low-Beta Section

PAX

One of the most challenging aspects of hadron physics is represented by the proton spin and its interpretation in terms of its internal constituents. The production of a beam of polarized antiprotons would represent a breakthrough in the field, allowing to experimentally access way a series of physics observables related to the proton spin. The PAX Collaboration is performing a series of measurement at the COSY ring to study in detail the mechanisms that could lead to an intense beam of polarized antiprotons. More: PAX …

Spectrometer

Exotic Atoms

Exotic atoms, where electron shells are replaced by a heavier negatively charged particle like muons, pions, or antiprotons, cover dimensions ranging from the atomic down to the nuclear scale. For elementary systems, e.g. pionic hydrogen, the pion-nucleon scattering lengths are directly accessible by means of X-ray spectrocsopy. More: Exotic Atoms …
