Frequency-Agile Instrumentation for High Field DNP/EPR Spectroscopy | Dr. Thorsten Maly | Session 19July 28, 2021
The 19th session of the Global NMR Discussion Meeting was held on 24th November 2020 via Zoom. Dr. Thorsten Maly gave a talk on versatile, frequency-agile instrumentation for high field dynamic nuclear polarization/electron paramagnetic resonance spectroscopy. The video was recorded live during the presentation and serves as an educative lecture.

Abstract: To further improve the DNP methodology it is crucial to understand the EPR properties of the DNP sample at the field of the DNP experiment. However, gyrotron-based DNP system only
offer limited flexibility to extract EPR parameters. In this tutorial, I will review frequency-agile
instrumentation suitable for high-frequency DNP and EPR spectroscopy. I will discuss strategies
for generating and detecting microwave radiation and will present the fundamental basics of quasi-
optics, necessary to separate the incident from the reflected microwave beam.
