Major advances in experimental nuclear and particle physics are often motivated by the need to answer challenging questions. In 2009, Monreal and Formaggio were motivated by the problem of measuring the absolute mass of the neutrino to propose the technique that would come to be called cyclotron radiation emission spectroscopy (CRES). They needed to measure the energies of the electrons from tritium beta decay with extremely high precision, which could be achieved by measuring the frequency of the cyclotron radiation from many individual magnetically trapped electrons. The technique was put into practice first by the Project 8 Collaboration and then by the He6-CRES Collaboration for the study of nonstandard weak interactions. In this review, we present the CRES experiments that have been performed to date, describe the phenomenology of CRES that has so far been explored, and cover potential applications of CRES that have been proposed.

回旋加速器辐射发射光谱


实验核物理学和粒子物理学的重大进步往往是由于需要回答具有挑战性的问题。2009 年，Monreal 和 Formaggio 受到测量中微子绝对质量问题的激励，提出了后来被称为回旋加速器辐射发射光谱 （CRES） 的技术。他们需要以极高的精度测量氚 β 衰变的电子能量，这可以通过测量来自许多单个磁捕获电子的回旋加速器辐射频率来实现。该技术首先由 Project 8 Collaboration 付诸实践，然后由 He6-CRES Collaboration 用于研究非标准弱相互作用。在这篇综述中，我们介绍了迄今为止已经进行的 CRES 实验，描述了迄今为止已经探索的 CRES 现象学，并涵盖了已提出的 CRES 的潜在应用。
