COSY: A cooler‐synchrotron for the KFA Jolich

The concept and the status of the cooler‐synchrotron COSY under study at the Institute for Nuclear Physics of the KFA Julich are presented. This storage ring with phase space cooling and RF acceleration is designed to accept light ions injected from the existing cyclotron JULIC or protons from the LINAC of the proposed neutron spallation source (SNQ). The lay‐out of COSY was developed in cooperation with the Universities in Nordrhein‐Westfalen and the meets the experimental requirements of variable and high quality beams which are necessary for the future nuclear research program under discussion.
