Description
Summary:Project of powerful submillimeter wave generator based on intense interaction of a relativistic electron beam with a magnetized plasma is developed at BINP RAS in collaboration with NSU. In presented experiments at the GOL-PET facility, the beam with parameters 0.8 MeV/15 kA/6 μs is injected into a magnetized (induction up to 4.7 T) plasma column with diameter 6 cm, length 2.5 m and the density 8x10 14 ÷2 x10 15 cm −3 [1]. Experiments showed that at this plasma density, the emission from the beam-plasma system is concentrated in a flux directed along the axis of the column. We measured the power and the spectral composition of this flux in the frequency band 0.1÷0.8 THz. Our studies were focused on the role of strong plasma density gradients in generation of the flux.
