提出了一种新的核自旋微波激射器，适用于中子电偶极矩的高精度测量。为了验证这一想法，一个以自旋极化129Xe气体为工作物质的自旋激射器被构建了出来。在详细研究了自旋激射器在普通自旋激射机构中的运行后，我们在激射器的反馈回路中引入了一个额外的组件，以实现所提出的激射机制。观察到横向自旋的自持续振荡，这清楚地表明由新的自旋激振机制实现了自旋激振。
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.
