The HADES spectrometer and a time-of-flight detector based on long-sized (50-250 cm) scintillation counters are described. The detector is designed for identification of electrons, pions, and protons with momenta of 0.1-1.5 GeV/c at a flight distance of 220-250 cm. The operating conditions are analyzed, and the requirements to the detector and counter design are formulated. The design of the counters and their arrangement in the spectrometer are considered. The results of experimental studies of such characteristics of long counters as the light attenuation length in a scintillator and temporal and sparial resolutions, depending on the location of the point of the particle`s hit on the counter, are presented. Analysis of the data has shown that the main factor determining the spatial resolution of long counters is the quality of the polishing of the side faces of the scintillators.
