STUDY OF THE LIGHT YIELD OF PLASTIC SCINTILLATORS IN A MAGNETIC-FIELD

Relative change in the light yield in polystyrene-and acrylic-based pl astic scintillators was measured as a function of the magnetic field. Scintillator samples of various thickness and configurations were exci ted by photons from Co-60 and Cs-137, electrons from Sr-98, and alpha- particles from Pu-239. On increasing the magnetic field from 0 to 2.1 T, the light yield increased by 6-10% in the scintillators irradiated with electrons and photons and remained practically unaffected in the scintillators irradiated with alpha-particles.
