Abstract

The invention provides a high-voltage electrostatic acceleration tube for strong current ions, which includes an acceleration tube body; the acceleration tube body specifically includes an inlet cylinder, an inlet flange, an inlet flange jacket, a magnetic mirror device, an accelerating electrode, and a double electron cloud space charge Lens device, outlet flange jacket, outlet flange, outlet cylinder, insulation ring, pressure equalizing ring and insulation column, etc.; there is a magnetic mirror device between the inlet flange jacket and the inlet cylinder, and the outlet flange jacket A double electron cloud space charge lens device is arranged between the exit cylinder and the radius of the central circular hole of each accelerating electrode decreases sequentially along the beam transmission direction. The present invention utilizes the focusing electric field and the beam-plasma interaction to respectively enhance the ion focusing force in the acceleration area and the area of ​​the entrance and exit of the acceleration tube, suppress the beam dispersion caused by the strong space charge effect under the condition of a strong ion beam, and reduce the beam loss and inhibition The increase of the beam emittance can realize the efficient and stable acceleration of the high-current ion beam.
