This paper describes results of GOL-PET experiments on subterahertz (0.1-0.5 THz) emission from a magnetized plasma column during passing of a high-current (similar to 10 kA) relativistic (similar to 0.6 MeV) electron beam. The subterahertz radiation is generated in the plasma due to high-level turbulence induced by two-stream instability of the electron beam. These experiments are carried out at the specialized GOL-3T device. For the plasma density range 10(14)-10(15) cm(-3), we have studied emission dynamics from the plasma column in its transverse and longitudinal directions. The spectral composition and polarization of the radiation was also investigated.
