Heating the vapor cell without introducing magnetic field is a requirement for magnetically sensitive atomic instruments. But, the magnetic field is inevitable in the electrical heating mode. Therefore, how to realize the optimal design of electric heating film becomes an important issue in practice. To solve this problem, a quantitative analysis of magnetic field cancellation is conducted, and a quadra-layered multipole moment heating film is proposed with optimized conduction pattern. First, considering that the wire number and current directions may influence the magnetic field, a different conduction pattern in a single-layer heating film is analyzed. Second, the electromagnetic multipole moment of multilayer heating film is further analyzed. Based on the study of self-cancellation effect of magnetic field, the configuration of the designed heating film is optimized with minimal magnetic field. Finally, sufficient simulations and experiments are developed to verify the superiority of the designed quadra-layered multipole moment heating film on magnetic field minimization.

一种具有自消磁场的四层多极矩加热膜

在不引入磁场的情况下加热蒸气室是磁敏原子仪器的要求。但是,在电加热模式下,磁场是不可避免的。因此,如何实现电热膜的优化设计成为实践中的一个重要问题。为了解决这个问题,对磁场抵消进行了定量分析,并提出了一种具有优化传导模式的四层多极矩加热膜。首先,考虑到线数和电流方向可能会影响磁场,分析了单层加热膜中的不同传导模式。其次,进一步分析了多层加热膜的电磁多极矩。基于磁场自抵消效应的研究,设计的加热膜的配置以最小的磁场进行了优化。最后,进行了充分的模拟和实验,以验证所设计的四层多极矩加热膜在磁场最小化方面的优越性。
