A matched magnetic circuit was also designed. We used pierce method to design the gun, 3D simulation software to optimize the optical system and magnetic circuit. A three-beam pierce electron optical system was designed to produce a total current of 3×0.87A divided equally among the three beams at an accelerating potential of 15kV, and the radius of beam tunnel is 1mm. It also consists of solenoid magnet structures to optimize the beam radius, which produce 0.52T magnetic field. This gun have vast prospect, which can be used for vacuum electronic devices, photonic crystals gyrotron and artificial electromagnetic new type medium.","PeriodicalId":123409,"journal":{"name":"2017 10th UK-Europe-China Workshop on Millimetre Waves and Terahertz Technologies (UCMMT)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122050669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
