Measurement of particle track coordinates according to the centre of gravity of light flash in a scintillator

Results of studies of a position-sensitive scintillation counter are presented. The coordinates of tracks in the counter have been calculated by the centre of gravity of light flash in the scintillator. The light flash distribution has been measured by a system of strip lightguides. The accuracy in measuring the track coordinates of electrons from a 106Ru radioactive source is 3.0 mm. When the tracks are imitated by a collimated light diode (the slit width is 0.8 mm), the accuracy in determining the coordinate light source is 1.27 mm. Studies are presented in the form of the light flash in the scintillator from the 106Ru particles, the collimated light diode and cosmic rays. The intensity distributions from light diode and cosmic rays are well coincide in shape, but distribution width from the radiation source is slightly more
