Measurement of the plastic scintillator response in the magnetic field

We present the results of measurements of the light yield dependencies for the plastic scintillators on magnetic field value and orientation. The magnetic field value was changed from 0 up to 3.8 T. Scintillators were irradiated by electrons (Cs-137 and Bi-207) and by alpha-particles (Am-241). The detected light spectra in the electron irradiating cases show two dependencies: the first one is dependence on the magnetic field value only and the second-light output is dependent on the magnetic field orientation when the radioactive source is outside of the scintillator. The value and behavior of the first dependence agree with data published earlier. Under alpha-particle irradiation the light output does not depend on the magnetic field value and orientation practically.
