Abstract :
Microwave cavity is the core part to the physics package of hydrogen maser. The most suitable mode to achieve hydrogen maser self-oscillation was considered and dimensions of the cavity with 1.42G cavity frequency in TE011mode were calculated. The calculated result of the cavity was confirmed by FEM simulation. Then the factors which may affect the stability of Hydrogen maser were analysed. Finally, the maser oscillation signal was obtained and the stability of the signal was tested.
