Abstract :
High-power terahertz emission from magnetized plasma during intense relativistic electron beam-plasma interaction is studied at the GOL-PET facility. The specific power density of the radiation reaches the level ~ 1 kW/cm3 in 0.2 ÷ 0.6 THz frequency band. The spectral power density of this terahertz radiation is located close to the upper-hybrid plasma frequency and at its double value.
