Spectral changes of bremsstrahlung plasma bunch generated under autoresonance in a long mirror

In this study, different scenarios of gyromagnetic autoresonance (GA) in a reverse magnetic field of a long mirror trap were realized. A detailed study of the spectral-angular distribution of X-Ray radiation (XR) in various experimental modes was conducted. The experimentally observed temporal behavior of the XR confirmed the modeling results of the dynamics of the generated plasma bunches with an energetic electron component, both in the GA phase and in the confinement mode.
