Project 8: Using Radio-Frequency Techniques to Measure Neutrino Mass
摘要：
Project 8实验的目的是利用氚的β衰变来测量中微子的质量。β衰变电子的能量将用一种新的技术来测量：当电子在均匀的磁场中运动时，它们的回旋辐射将被探测到。每个电子的回旋辐射频率与其总相对论能量成反比;因此，通过观察回旋辐射，我们可以精确测量电子能量。该技术的优点包括可扩展性、出色的能量分辨率和低背景。该合作正在使用原型实验来研究该技术与$^{83m}$ Kr源的可行性。证明从$^{83m}$ Kr看到17.8 keV和30.2 keV转换电子的能力将表明，有可能用回旋辐射测量氚β衰变电子能量（$Q \approx 18.6$ keV）。将讨论原型、分析和信号提取技术的进展，以及对实验潜在未来的估计。
英文摘要：
The Project 8 experiment aims to measure the neutrino mass using tritium beta decays. Beta-decay electron energies will be measured with a novel technique: as the electrons travel in a uniform magnetic field their cyclotron radiation will be detected. The frequency of each electron's cyclotron radiation is inversely proportional to its total relativistic energy; therefore, by observing the cyclotron radiation we can make a precise measurement of the electron energies. The advantages of this technique include scalability, excellent energy resolution, and low backgrounds. The collaboration is using a prototype experiment to study the feasibility of the technique with a $^{83m}$Kr source. Demonstrating the ability to see the 17.8 keV and 30.2 keV conversion electrons from $^{83m}$Kr will show that it may be possible to measure tritium beta-decay electron energies ($Q \approx 18.6$ keV) with their cyclotron radiation. Progress on the prototype, analysis and signal-extraction techniques, and an estimate of the potential future of the experiment will be discussed.
