Title:
イオン源及びイオンビーム発生方法
Document Type and Number:
Japanese Patent JP6668281
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ion source capable of outputting an ion beam of a heavy-current and a high energy and an ion beam generating method, without using a liner accelerator.SOLUTION: An ion source 10 comprises; a cylindrical outside magnetic part 16; an inside magnetic part 20 arranged while having a constant space from the outside magnetic part 16; a positive electrode 25 arranged on a close side of the space; a negative electrode 26; a hole thruster 11 that applies an electric field to a direction orthogonal to a magnetic field, and accelerates an ion in a plasma; an inner positive electrode 30 in which one end is opened; an external negative electrode 32 arranged in the circumference of the inner positive electrode 30; and a plasma focus part 13 in which an ion beam to be flown is accelerated to an open end direction of the inner positive electrode 30 by a Lorentz force occurred by a current flowing between the electrode and an own magnetic field generated by the current, and outputs them while compressing in an open part of the inner positive electrode 30.SELECTED DRAWING: Figure 1
