Compact beam position monitor using a segmented toroidal coil Open
An inductive compact beam position monitor based on a segmented toroidal coil surrounding the charged particle beam has been investigated. It makes use of the induced voltages in the windings instead of the induced charge imbalance on capa…

Measurement of deuteron carbon vector analyzing powers in the kinetic energy range 170-380 MeV Open
A measurement of vector analyzing powers in elastic deuteron-carbon scattering has been performed at the Cooler Synchrotron COSY of Forschungszentrum Jülich, Germany. Seven kinetic beam energies between 170 and 380 MeV have been used. A ve…

Spin tune mapping as a novel tool to probe the spin dynamics in storage rings Open
Precision experiments, such as the search for electric dipole moments of charged particles using storage rings, demand for an understanding of the spin dynamics with unprecedented accuracy. The ultimate aim is to measure the electric dipol…

Phase Locking the Spin Precession in a Storage Ring Open
This Letter reports the successful use of feedback from a spin polarization measurement to the revolution frequency of a 0.97 GeV/c bunched and polarized deuteron beam in the Cooler Synchrotron (COSY) storage ring in order to control both …

Entwicklung eines Rogowski Spulen Strahlpositionsmonitor zur Messung von elektrischen Dipolmomenten an Speicherringen Open
One of the unsolved phenomena in physics is the matter-over-antimatter dominance in our universe. The known CP violating processes of the Standard Model of particle physics are not sufficient to explain this asymmetry. Therefore, additiona…

Development and Application of Rogowski Coils as Beam Position Monitors Open
We have developed segmented Rogowski coils as a beam position monitors at the storage ring COSY Jülich as an alternative to the conventional monitors installed there. These coils feature a torus with two or four segments, each densely cove…

Beam Based Calibration of a Rogowski Coil Used as a Horizontal and Vertical Beam Position Monitor Open
Electric Dipole Moments (EDMs) violate parity and time reversal symmetries. Assuming the CPT-theorem, this leads to CP violation, which is needed to explain the matter over antimatter dominance in the Universe. So far no direct EDM measure…

Development of New Beam Position Monitors at COSY Open
Electric Dipole Moments (EDM) violate parity and time reversal symmetries. Assuming the CPT-theorem, this leads to CP violation, which is needed to explain the matter over antimatter dominance in the Universe. Thus, a non-zero EDM is a hin…
