title: The Diogene 4 pi detector at Saturne.
abstract: Diogene, an electronic 4 pi detector, has been built and installed at the Saturne synchrotron in Saclay.  The forward angular range (0 degree-6 degrees) is covered by 48 time-of-flight scintillator telescopes that provide charge identification.  The trajectories of fragments emitted at larger angles are recorded in a cylindrical 0.4-m3 Pictorial Drift Chamber (PDC) surrounding the target.  The PDC is inside a 1-T magnetic field; the axis of the PDC cylinder and the magnetic field are parallel to the beam.  Good identification has been obtained for both positive and negative pi mesons and for hydrogen and helium isotopes.  Multiplicities in relativistic nucleus-nucleus reactions up to 40 have been detected, limited mainly by the present electronics.
