Description
DESCRIPTION (provided by applicant): We propose to develop a compact, cost-effective Traveling Wave Tube (TWT) amplifier at 263 GHz with 50 W of peak power, 5 W of continuous wave power and 5% 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 gt300 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 d
