摘要

现代动态核极化(DNP)实验通常利用回旋管源辐照140-593 GHz的电子自旋。然而,回旋管的总拥有成本、尺寸和复杂性限制了它的广泛采用。采用低成本和更紧凑的资源可以对DNP社区产生重大影响。该贡献描述了263 GHz EIK的开发,DNP核磁共振样品最佳辐照传输线的设计,以及DNP实验的详细性能表征。

Opportunities and Challenges for EIK's in DNP NMR Applications
Modern Dynamic Nuclear Polarization (DNP) experiments often utilize gyrotron sources for irradiation of electron spins at 140–593 GHz. The total cost of ownership, size, and complexity of gyrotrons, however, limits wider adoption. The introduction of lower-cost and more compact sources can have a significant impact on the DNP community. This contribution describes the development of a 263 GHz EIK, design of transmission line for optimal irradiation of the DNP NMR sample, and detailed performance characterization for DNP experiments.
