| Zusammenfassung | We describe results on automatic detection of fast-neutron induced recoil-proton tracks in micro-capillary bundles filled with organic liquid scintillator, viewed by an intensified CCD camera. This imaging neutron spectrometer was developed for high position-resolution (few tens of μ m) imaging and medium-quality energy spectroscopy of neutrons in the energy range 2-20 MeV. In addition to recoil proton events which display a continuous extended track structure, CCD images include also a multitude of isolated spots of varying intensity ("blobs") that originate from several different sources, such as fragmented proton tracks, electrons from gamma-rays, short heavy-ion tracks, as well as events and noise that occur in the image intensifier and CCD. In order to identify the extended-track recoil proton events and separate them from these background events, a computerized, rapid and automatic track-recognition procedure was developed. Based on the analysis of track parameters such as: track area, light intensity, track length and width, the method is capable of distinguishing few recoil protons from the surrounding numerous background events typically found in each CCD frame. |
