Investigation of the spectral and energy characteristics of bunches of space charge in turbulent electron beams

The investigation of the spectral and energy characteristics of bunches of a space charge in the turbulent electron beams is presented. The results of numerical modeling and experimental studies carried out on laboratory layout generator are proposed. It is shown that for the formation of an electron beam with a multirate structure a pronounced fundamentally important aspect is the presence of the initial spread of electrons velocity in the electron gun, in particular with grid structures. There is an intensive form of dense bunches of space charges in electron beams with a strong multi-rate structure. Spatial and temporal oscillations of bunches of the space charge are a source of broadband noise fluctuations.
