Abstract
The characteristics of a 50-cm-long module of the scintillation time-of-flight hodoscope have been studied. It has been determined that the coordinate resolution and detection efficiency of the module depend on the voltages applied to the voltage dividers of the photomultiplier tubes and the distance from the hip point of a particle to the photomultiplier tubes. The module has been tested using both a secondary electron beam of the Pakhra accelerator (Lebedev Physical Institute, Russian Academy of Sciences) with an energy of 20 MeV and a 90Sr+90Y radioactive source. The tests show that the minimum values of the coordinate resolution are σx ≈ 0.1 and 1.3 cm, respectively, and the detection efficiency is ε ≈ 53%.
期刊介绍：
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
