Description
Beam-plasma systems widely exist in the outer space. Electromagnetic radiation from such sources has been measured and interpreted by astrophysics researchers since the middle of the last century. Verification of astrophysical models of different mechanisms of space plasma electromagnetic radiation requires supporting laboratory experiments. Since 2010 we carry out such experiments and theoretical research by the collaboration of BINP and NSU [1]. Experiments described in the paper [1] were realized on the GOL-3 facility that was constructed and applied to study the beam-plasma interaction for achieving fusion plasma parameters. To carry out the experiments on investigation of the transformation processes of the plasma waves-electromagnetic radiation, we reconstructed the GOL-3 facility. At the first step of the reconstruction, the GOL-3T device was created and then this device was additionally modified for research on the application of the beam-plasma system as a source of terahertz radiation. This modified device GOL-PET [2] is currently used for the beam-plasma experiments.
The presented paper will describe results of GOL-PET experiments on the emission from the beam-plasma system in the frequency interval 0.1-0.7 THz. We will present results of the measurements of the spectral composition and direction of the emission from a magnetized plasma column during passing of a high current relativistic electron beam ($\sim$0.6 MeV, $\sim$10 kA, 8 μs). The experimental results will be composed with theoretical study of the radiation generation by this system. Prospects of the application of such system as a powerful source will be discussed as well.
