Acquisition of a High Field, Low Temperature Platform for Fundamental Measurements

这个核磁共振奖是为了开发一种最先进的高场低温（HBLT）磁铁，这种磁铁可以在低温下提供高磁场。这种磁体基础设施将使许多重要的基本测量具有前所未有的精度：电子的磁矩（通常称为它的g值）精细结构常数alpha3。正电子和电子的比值g值，是检验CPT不变性与重子的最佳方法。质子质量与电子质量之比反质子的磁矩这些测量在最深处测试了最基本和最基本的物理定律。大量的基本测量，令人难以置信的准确性，单粒子技术的优雅，以及技术衍生品，弥补了实验的困难和耗时的本质。过去，数十名本科生和数十名研究生参与了类似的研究基础设施，这种情况将继续下去。实验将作为许多研究生和博士后高级培训的一部分进行，许多参与的本科生将获得最前沿科学的经验。

This MRI award is for the development of a state-of-the-art high-field, low-temperature (HBLT) magnet that provides a high magnetic field at low temperature. This magnet infrastructure will allow a number of important of fundamental measurements of unprecedented accuracy:1. the magnetic moment of the electron (often called its g value)2. the fine structure constant alpha3. the ratio of positron and electron g values, the best test of CPT invariance with baryons4. the ratio of proton and electron masses5. the magnetic moment of the antiprotonThese measurements test the most basic and fundamental laws of physics at the deepest level. The large number of fundamental measurements, the incredible accuracy, the elegance of the one particle techniques, and the technological spinoffs, compensate for the difficulty and time consuming nature of the experiments. Scores of undergraduates and dozens of graduate students have been involved in using similar research infrastructure in the past and this will continue. Experiments will be carried out as part of the advanced training of many graduate students and postdocs, and many participating undergraduates will get hands on experience with cutting edge science.
