Description

technical field [0001] The invention relates to a transmission device suitable for nuclear pore membrane atmospheric irradiation. The main application fields of this device include nuclear pore membrane irradiation processing, nuclear pore membrane preparation, etc. Background technique [0002] Nuclear pore membrane, also known as nuclear microporous membrane or heavy ion microporous membrane, is prepared mainly by 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 energy. The energy of small accelerators is 3-5MeV / u. It is characterized by low equipment prices and low barriers to entry. There are dozens of low-energy accelerators all over the world. Using small accelerators to produce nuclear pore membranes is widely used at...
