Abstract

Nuclear spin maser based on a new masing mechanism is proposed, which is applicable to high-precision measurements of the electric dipole moment of neutron. To test this idea, a spin maser with a spin-polarized 129Xe gas as a working substance was constructed. After a detailed investigation of the spin maser operation in an ordinary spin-masing mechanism, we introduced an additional component in the feedback loop of the maser in order to implement the proposed masing mechanism. A self-sustained oscillation of transverse spins has been observed which clearly indicates a realization of spin masing arising from the new masing mechanism.
