Abstract

The invention discloses a method and device for measuring the ion beam eccentric angle of a Hall ion source, and the method comprises the steps: importing a picture, photographed by a CCD camera, of acircumferential discharge channel when the Hall ion source works into MATLAB for processing, and converting the picture into a picture matrix format; and calculating pixel value distribution in the photo image by MATLAB, and calculating an ion beam current vector eccentric angle. According to the invention, the problem that the eccentric angle of the ion beam is difficult to measure is effectively solved.

Description

Technical field [0001] The invention relates to the technical field of image processing, in particular to a method and a device for measuring the eccentric angle of the ion beam of a Hall ion source. Background technique [0002] The Hall ion source is a device that ionizes neutral atoms or molecules and draws an ion beam from it. The Hall ion source ionizes the gas charged into the vacuum chamber by using the emitted electrons under the interaction of the electric field and the magnetic field in a vacuum environment, and emits ions under the action of the electric field and the magnetic field. As a gridless ion source, the Hall ion source is widely used in general auxiliary coating fields because of its low maintenance cost. The luminescence of the beam in the ion source channel can reflect the distribution of ions generated by the collision in the channel. When working under ideal axial symmetry, the ion beam direction should coincide with the ion source axis. However, due t...
