摘要：

For the investigation of correlated fission characteristics like fragment mass and energy-distributions the double (v, E) spectrometer VERDI is being constructed. With this instrument we aim at the simultaneous measurement of pre- and post-neutron masses, avoiding prompt neutron corrections. From the simultaneous measurement of pre- and post-neutron fission-fragment data the prompt neutron multiplicity may be inferred as a function of fragment mass and total kinetic energy. In order to arrive at a mass resolving power Delta A < 2, ultra-fast and radiation hard time pick-up detectors based on artificial diamond material are under investigation. We report about the timing resolution of these detectors obtained with fission fragments, and discuss the first experiment with a single (v, E) version of the VERDI spectrometer performed at the Budapest Research Reactor.
