Description

technical field [0001] The invention relates to a nuclear pore membrane automatic production device and method with an adaptive beam current, and relates to the technical field of nuclear pore membrane irradiation production and manufacture. Background technique [0002] Nuclear pore membranes are the most precise microporous filtration membranes in the world. It is a porous plastic film with densely packed small holes, each of which has the same shape and size. The nuclear pore membrane has many specifications, the membrane thickness ranges from 5 microns to 60 microns, the pore diameter ranges from 0.2 microns to 15 microns, and the pore density ranges from 1-10 to the 9th power per square centimeter. [0003] Nuclear pore membranes are usually perforated by heavy ions provided by high-energy accelerators. Heavy ion perforation is the most critical part of the production process of nuclear pore membranes. Few of the existing technologies have heavy ion accelerators suitab...
