Description
- Abstract
- We propose to develop a compact, cost-effective traveling wave tube (TWT) amplifier at 395 GHZ with 1.5 w continuous wave power and 20 GHZ instantaneous bandwidth for application in dynamic nuclear polarization (DNP) enhanced solid-state and solution-state NMR and electron paramagnetic resonance (EPR) spectroscopy. With DNP, the inherently small signal intensities in a NMR experiment can be enhanced by up to two orders of magnitude. This significantly increased overall sensitivity will be highly beneficial for analytical applications of NMR spectroscopy as well as in the structure determination of BIO-macromolecules using NMR methods. Currently, DNP is performed with either low power solid-state sources (whose output power is limited to a few MW at frequencies > 300 GHZ) and at low temperatures in the range of 20-30 k (to compensate for low microwave power) or with large, gyrotron systems which can generate 50 w of power. Gyrotrons are expensive and do not possess sufficient tuning bandwidth (
