Abstract:
The fundamental possibility of a new method for controlled collective ion acceleration by electron bunches of high-current relativistic picosecond beams has been proved. Dense relativistically rotating electron bunches are formed using a cusp magnetic system by their capture in a special magnetic trap. An electron bunch is filled with ions when it interacts with a preliminarily prepared plasma bunch with a certain density. Then, the effective potential well of the magnetic trap is stepwise shifted synchronously with the motion of ions by means of a system of turns with controlled currents. This ensures the displacement and confinement of electrons in the direction of acceleration. The shift of the center of the well at each step is chosen such that ions are in the region of acceleration by a high self electric field of the electron bunch. In contrast to the known methods for collective acceleration, the proposed method makes it possible to avoid the mismatch of the electron and ion components of bunches, disruption of the acceleration of ions, and development of numerous instabilities, because the duration of the acceleration cycle is in the nanosecond range.
