Description

Technical field [0001] The invention relates to a transmission device suitable for atmospheric radiation of nuclear pore membranes. The main application areas of this device include nuclear pore membrane irradiation processing and nuclear pore membrane preparation. Background technique [0002] Nuclear porous membrane, also known as nuclear microporous membrane or heavy ion microporous membrane, is prepared mainly including heavy ion irradiation and chemical etching. Among them, heavy ion irradiation is the most critical process. Heavy ion irradiation usually uses reactors and heavy ion accelerators. Heavy ion accelerators can be divided into small low-energy accelerators and large high-energy accelerators according to their energy. The energy of the small accelerator is 3-5MeV / u. It is characterized by low equipment price and low entry barrier. There are dozens of low-energy accelerators around the world. The use of small accelerators for nuclear pore membrane production is w...
