Heavy ion production device for industrial production of nuclear track membrane

Abstract

The invention relates to a heavy ion production device for industrial production of nuclear track membrane. The heavy ion production device comprises an ion source, an LEBT beam line, a particle accelerator, an HEBT beam line and a membrane irradiation terminal; the ion source is used for generating a heavy ion beam in a high charge state and carrying out primary acceleration on the heavy ion beam; the LEBT beam line is used for analyzing the heavy ion beam and transmitting the heavy ion beam to the particle accelerator in a matching manner; the particle accelerator performs main accelerationon the heavy ion beam and then injects the heavy ion beam into the HEBT beam line; the HEBT beam line splits the injected heavy ion beam into a plurality of heavy ion beams and then transmits the heavy ion beams to a plurality of membrane irradiation terminals, and the membrane irradiation terminals lead out the heavy ion beams and irradiate a thin membrane placed in the atmospheric environment. Due to the fact that the thin membrane can be placed in the atmospheric environment to be irradiated, the thin membrane is convenient and rapid to replace, the thin membrane replacing time is greatly shortened, multiple terminals can irradiate the thin membrane at the same time, the irradiation efficiency of the thin membrane is greatly improved, and thus the production efficiency of the nuclear track membrane is improved.

Description

technical field [0001] The invention relates to a heavy ion production device, in particular to a heavy ion production device for nuclear pore membrane industrial production, and belongs to the technical field of nuclear pore membrane production. Background technique [0002] Heavy ion nuclear pore membranes have an irreplaceable and excellent role in water treatment, air filtration and clean energy (such as lithium-ion battery separators), and have a unique role in new special functional materials, and are expected to be used in new civilian and military materials. There have been many breakthroughs. [0003] At present, there are special devices for nuclear pore membrane irradiation in the world, which can provide heavy ion single nucleus energy of about 3MeV / u. The thin film to be irradiated can only be placed in a vacuum state, and only one irradiation terminal works at the same time. The irradiation efficiency of thin films is not high, resulting in low production effi...
