中文摘要
这个精密测量项目旨在以极大提高的精度测量以下四个基本量:1)电子的磁矩(通常称为其g值);2)精细结构常数;3)正电子与电子的比值g值;4)质子和电子质量的比值。精细结构常数的测量,以及g的测量,将测试QED到一个前所未有的精度水平。捕获正电子的技术的极大改进将有助于比较电子和正电子的测量g值,从而在轻子系统中提供CPT不变性的最佳测试。
英文摘要
This project in precision measurements seeks to measure at greatly improved accuracy the following four fundamental quantities: 1) the magnetic moment of the electron (often called its g value) ; 2) the fine structure constant; 3) the ratio of positron and electron g values; and 4) the ratio of the masses of the proton and electron. The measurement of the fine structure constant, along with the measurement of g, will test QED to an unprecedented level of accuracy. Greatly improved techniques for trapping positrons will aid the comparison of measured g values for the electron and positron to provide the best test of CPT invariance with a lepton system.
