Folded Nuclear Magnetic Resonance Gyroscope

[09:28 . 99]加州大学欧文分校该项目的目的是研究一类依赖于原子惯性特性的新型惯性仪器。具体来说，将研究Rb和Xn同位素的自旋极化核的进动是如何被捕获的。在小体积内可以编码和携带物体旋转的惯性信息。据估计，拟议的技术将达到与最先进的传统陀螺仪相当的性能水平，但成本只是后者的一小部分。该项目将解决几个基本挑战，包括在微型电池上操作原子陀螺仪的可行性，微制造线圈中的磁场均匀性，组装和制造缺陷的影响，碱金属蒸气和稀有气体的晶圆级填充方法，微型非磁性加热器的开发，以及电池形状和缓冲气体对核弛豫时间的影响。这项研究有望推动创新传感概念、信号处理和系统级实现领域的科学知识。这个高度跨学科的项目将通过团队合作为本科生和研究生提供独特的教育体验。高中生也将通过独特的暑期实习参与该项目。

0928999Andrei ShkelUniversity of California, IrvineThe objective of this project is to investigate a new class of inertial instruments relying on inertial properties of atoms. Specifically, work will be made to investigate how the precession of spin-polarized nuclei of Rb and Xn isotopes ?caged? in a small volume can encode and carry inertial information about rotation of objects. It is estimated that the proposed technology will achieve performance levels comparable to state-of-the art conventional gyroscopes, but at a fraction of their cost. Several fundamental challenges will be addressed in the project, including the feasibility of operating an atomic gyroscope with a miniature cell, magnetic field uniformity in microfabricated coils, effects of assembly and fabrication imperfections, methods for wafer-level filling of alkali metal vapor and noble gases, development of miniature non-magnetic heaters, and the effect of cell shape and buffer gases on the nuclear relaxation time. This research is expected to advance scientific knowledge in the areas of innovative sensing concepts, signal processing, and system-level implementation. This highly multidisciplinary project will provide unique educational experience for undergraduate and graduate students through team collaborations. High school students will also participate in this project through unique summer internships.
