| Abstract: | The research objective, process and results of 5 MHU CT tubes are introduced, and the technical difficulties including the design of precision electron gun, rotating anode target structure and the dynamic balance of ultra-high speed rotation system are described. On this basis, a lot of simulations are carried out and the CT tubes are developed. The practical test results prove the correctness of the design scheme. |
