氢原子频标中贮存泡内壁的成膜状态直接决定跃迁信号的产生及指标,贮存泡的涂敷和烧结工艺成为氢原子频标研制中的一项关键技术。通过分析聚四氟乙烯和聚全氟乙丙稀树脂的热处理特性以及氢原子频标对成膜的要求,分别针对蓝宝石氢原子频标和被动型氢原子频标贮存泡的特点,给出了相应的涂敷和烧结工艺。实际氢原子频标系统的测试表明,该涂膜工艺满足氢原子频标的使用要求。
The film formation state of the inner wall of the storage bubble in the hydrogen atomic frequency standard directly determines the generation of the transition signal and the index. The application and storage of the storage bubble become a key technology in the development of hydrogen atomic frequency standard. By analyzing the heat treatment characteristics of polytetrafluoroethylene (PTFE) and poly (vinyl fluoride) (PAF) resin and the requirement of film formation by hydrogen atomic frequency, the characteristics of hydrogen storage in sapphire and passive hydrogen storage are given respectively The corresponding coating and sintering process. The actual hydrogen atomic frequency standard system test shows that the coating process to meet the requirements of hydrogen atomic frequency standard.
