The invention provides a neutron source facility based on a deuterium-tritium mixed beam. The neutron source facility comprises an ion implantation system, a target system and a sputtering source, wherein the ion implantation system is used for generating a deuterium-tritium mixed ion beam which is used for bombarding the target system, the target system comprises a target disk and a target base, a surface, facing to the ion implantation system, of the target disk comprises a hydrogen storage film, and the sputtering source is used for supplementing a hydrogen storage film feedstock to the target disk. In a process of bombarding the target system by the deuterium-tritium mixed ion beam, part of deuterium or tritium is continuously stored in the hydrogen storage film of the target system, and a subsequent deuterium-tritium mixed ion beam acts with the deuterium or tritium stored in the hydrogen storage film to generate neutrons when the subsequent deuterium-tritium mixed ion beam bombards a target; the condition in an experiment process of the traditional method that the yield of the neutrons is lowered continuously due to the fact that the content of tritium in a tritium target gradually decreases is avoided, and the self-sustaining of tritium is achieved; and meanwhile, a target material element is continuously supplemented to the target system by using the sputtering source, and the quality of the hydrogen storage film of the target disk is improved, so that the hydrogen storage capacity of the target disk is improved, then, the life of the target system is prolonged, and sustained high-flux neutrons can be obtained.

The invention discloses a temperature self-maintaining carbon dioxide and water vapor co-electrolysis device and an application method thereof. The device comprises a reaction kettle, a fuel electrodechamber and a tube-type solid oxide electrolysis cell, wherein the fuel electrode chamber and the tube-type solid oxide electrolysis cell are arranged in the reaction kettle and are connected in a sealed mode; and an air electrode chamber is arranged on the outer side of the tube-type solid oxide electrolysis cell, and the reaction kettle is internally provided with annular thermal insulation materials around the fuel electrode chamber and the tube-type solid oxide electrolysis cell.

The invention relates to a container-type aluminum electrode, which includes a container, a pressing plate and a first spring. The top of the container is provided with a top cover for covering the top opening of the container. The top cover is installed on the top wall or the top of the container through a first hinge. On the side wall, the pressure plate is installed on the side wall of the container through the second hinge, the top cover and the pressure plate are installed on the same side of the container, the pressure plate and the top cover are connected by the first spring, and there is a gap between the edge of the pressure plate and the inner wall of the container. There is a gap, and the pressure plate is located in the container, which divides the interior of the container into upper and lower spaces, and the space under the pressure plate is filled with aluminum particles. The invention adopts the collection of aluminum particles loaded in the container as the electrode. When the electrode material is excessively consumed and needs to be replenished, it is only necessary to add aluminum particles to the container. The replenishment of the electrode material and the maintenance of the electrode are simple and convenient. When replenishing the aluminum particles, Just open the top cover, the first spring can drive the pressure plate to open upwards at the same time, and the operation process of replenishing the aluminum particles in the lower space of the pressure plate is convenient and quick.
