Fast Neutron Time‐of‐Flight Spectrometer Used with the Karlsruhe Isochronous Cyclotron

摘要: A high resolution, fast neutron, time‐of‐flight spectrometer used for neutron energies between about several hundred kiloelectron volts and 30 MeV is described. 1 nsec pulse occurring with a repetition rate of 20 kc obtained novel ``bunching deflection'' system operating on the internal beam fixed energy Karlsruhe isochronous cyclotron. By timing neutrons over 57 m flight path resolution 0.025 nsec/m at optimum was obtained. Detector counts are accumulated in 2×8000 channel time analyzer width. planned 180 an increase from present to 200 expected provide further improvements spectrometer.
