During the year 1991 the work of the members of our Institut fir Kernphysik (IKP) in the Forschungszentrcm Jiilich (KFA) concentrated on building the Cooler Synchrotron COSY-Jülich in close cooperation with other groups in the KFA, and on preparation of experiments to be carried out at COSY. Especially the latter work is being done in very close collaboration with scientists of CANU and together with groups and researchers from laboratories in foreign countries. We also have very strong cooperation with groups from the Research Center Rossendorf near Dresden. The experimental activity is accompanied by theoretical studies in the field of medium energy nuclear physics. The emphasis of our work necessarily aimed at the completion of COSY, which is expected to be available for experiments in 1993. Recommissioning of the injector cyclotron JULIC has started. The injection beam line to COSY has been set up. All COSY dipole magnets have been located and aligned . The quadrupole magnets have been delivered after a major delay. A large fraction of them has been tested and installed in the ring. Nearly all correction magnets have been delivered. The injection and extraction elements are available, also the magnets for the lines of the extracted beams. A section of the vacuum tube of the ring has been mounted and tested for ultra high vacuum. The electron cooler has been assembled for tests prior to installation in the ring. COSY control has aided in testing and commissioning of various components. The preparation of COSY experiments concerns the realization of multipurpose facilities and other experiments. The The large spectrometer BIG KARL for ejectiles with momenta up to 1.1 GeV/c has been moved into its new location. Upgrading of the entrance quadrupoles has been started. For other studies with extracted beams the large time of flight spectrometer TOF is under construction. Parts of its detectors are being built by CANU groups, also driftchambers for various experiments. Position sensitive solid state detector systems are being developed and built for experiments with BIG KARL and TOF. The main parts of a cluster target have been developed and assembled for experiments at the circulating COSY beam. The design of the 9 0®facility for a number ofinternal target experiments and ejectiles with momenta up to the maximum in COSY has been optimized regarding the detectors, resolution, time of flight and $\Delta$E particle discrimination. Research and development work was continued for the high-rate photon spectrometer and for the other COSY experiments. Detectors and equipment was acquired, built and tested. Studies have begun to make use of the COSY beam also for cancer therapy. Work going on in the field of theoretical nuclear physics is strongly connected with research projects at COSY and processes induced in the proton-antiproton interaction. [...] |
