[0002] The preparation of nuclear pore membranes depends on heavy ion accelerators. The heavy ions ejected by the accelerator bombard the polymer film to form latent tracks. The latent tracks are sensitized and chemically etched to finally obtain special nuclear pore membrane materials. In laboratory scientific research preparation, the irradiation of nuclear pore membranes is usually a single fixed plane with an area of ​​only a hundred centimeters, which cannot achieve continuous preparation of a larger area; and in order to better obtain a larger area of ​​nuclear pore membranes, it is necessary to be able to irradiate a larger area of ​​polymer films. As a large scientific device, the accelerator needs to carry out different experimental verifications in a target chamber with a fixed volume of beam extraction, and different experimental modifications are often required.
