title: An experimental study for the compact hydrogen maser with a TE111 septum cavity.
abstract: We have made experiments on our compact active hydrogen maser with the cylindrical TE111-mode septum cavity, which is almost one-half the conventional TE011-mode cavity in size. An inductive radiation signal was observed, but the maser did not produce self-oscillation. The system supports oscillation when the cavity is placed in an external feedback loop.
