Summary Outlook

Prototyping and Accelerator Physics at COSYDetector tests for PANDA and CBM

Preparation for HESRHigh-Energy Electron Cooling and High-Bandwidth Stochastic CoolingInternal Targets RF Manipulation techniques

COSY is essential to develop and establish these techniques for HESR

Polarized beams at COSY

Polarizing stored Antiprotons by spin-filtering

RampD work for storage ring EDM searches of charged particles

First direct EDM measurement ideal EDM injector COSY is essential to perform RampD work for PAX and EDM

HESR project status

New HESR beam accumulation scheme due to modularized start version of FAIR

Design work of the HESR is finalized and the construction phase started

Main HESR components are ordered (dipoles quadrupoles )

corresponds to roughly 30 of total project costs

COSY Upgrade

1 Improved closed-orbit control system for orbit correction in the micrometer range

Increasing the stability of correction-dipole power supplies

Increase number of correction dipoles and beam-position monitors (BPMs)

Improve BPM accuracy limited by electronic offset and amplifier linearity

Systematic errors of the orbit measurement (eg temperature drift)

2 Alignment of Magnets and BPMs

More precise alignment of the quadrupole and sextupole magnets

BPMs have to be aligned with respect to the magnetic axis of these magnets

3 Beam oscillations

Excited by vibrations of magnetic fields induced by the jitter of power supplies

Coherent beam oscillation

4 Longitudinal and transverse wake fields
