| 摘 要： | 利用电磁场微波理论, 对简化近似后的被动型氢脉泽微波腔模型建立了微波腔频率谐振方程、无载Q值以及填充因子的解析表达式. 通过计算找到了无载Q值与填充因子乘积最大时的微波腔尺寸. 实验表明, 新设计的微波腔的各项性能完全满足被动氢脉泽的使用要求. 该腔体的无载Q值达到9800, 填充因子值达到1.2, 并且该微波腔的原子填充区域是已有文献报道中体积最大的.

| Abstract: | According to the theory of electromagnetism, we establish the equation of resonance frequency for simplified model of cavity of passive hydrogen maser. We find the optimal dimension of the cavity, which makes the product of the Q value and the filling factor reach a maximal value. The experimental results indicate that the so designed cavity can be utilized undoubtedly for the passive hydrogen maser, and achieve the Q value of 9800 and the filling factor of 1.2. Furthermore, the resulting capacity of storage volume is the biggest is ever reported cavities of passive hydrogen maser. |
