[en] A 500-wire proportional-chamber telescope is described applied in the full-absorption spectrometer coordinate channel. The telescope comprises six proportional chambers (160x160) mm² with gaps between signal and high-voltage planes of 4 mm. The recording electronics are briefly described, chamber technical characteristics are given

[en] The automatic Hall detector drive (coordinator) of the MIKh-2 magnetometer is considered, used for pulse field measurements in collective accelerator adgesator chamber. The positioning accuracy relative to coordinator scales is less than 0.2 mm for radius and hight, and 0.5⁰ for asimuth. The coordinator section located at the chamber does not have any metallic elements. Manual and automatic mode control with computer communication has been provided. The control system uses a reverse decimal counter

[en] A possibility of use detectors on the base of plastic streamer tubes for precise particle coordinate determination is tested. The method, based on determination of charge centroid, which is induced by external electrodes, provides the space resolution deltasub(x)=530 μm, and resolution of the method based on drift time measurement is 110 μm < deltasub(x) < 350 μm. The electron drift velocity measured in the argon-isobutane gas mixture with a high isobutane concentration (1Ar:3C₄H₁₀) was (41.8+-4.3)x10⁵ cm/s. Coordinate accuracy obtained in both cases is better than that required to muon spectrometers with magnetized iron. It permits to use plastic streamer tubes for particle trajectory determination in such installations

[en] 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

[en] It is shown that plastic streamer tubes can be used to determine a particle coordinate with an accuracy of 500 μm by measuring the center of gravity of the charge induced on external electrodes and with an accuracy of 100-350 μm by measuring the drift time of electrons to the tube anode

[en] Results of studies of a position-sensitive scintillation counter are presented. The coordinates of tracks in the counter have been calculated from the centre of gravity of light intensity in the scintillator. The light distribution has been measured by a system of strip light guides. The accuracy in localization of 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 of the light source is 1.3 mm. Studies of the form of a light flash in the scintillator from the ₁₀₆Ru particles, the collimated light diode and cosmic rays are presented. (orig.)
