Highlights of the physics program at AGOR

摘要

The AGOR (Accelerateur Groningen ORsay) cyclotron has passed successfully the beam tests at the assembly site at Orsay during the first months of 1994. The final installation of the first european superconducting cyclotron is now being performed at Groningen. The beam guiding system, the location and equipments of the main experimental area are currently completed. The physics program is scheduled to start around the summer of 1995. A broad range of ions and energies (from 200 MeV protons, 100 MeV fully stripped ions down to 6 A. MeV lead beams) will become available. Specialized multi detectors systems are ready to be used in connection with the high acceptance spectrograph BBS in order to explore new modes in the nuclear continuum and the spin, spin-isospin response of nuclei using polarized proton and deuteron beams between 150 and 200 MeV. The nucleon-nucleon Bremsstrahlung (NN(gamma)) reaction is also proposed to be studied in order to provide a much better understanding of the elementary NN(gamma) process. . Of particular interest are the off-shell behaviour of the N-N interaction and hard photons production in nucleus-nucleus collisions at intermediate energies. (author). 9 refs., 8 figs.
