Title:
A HIGH RESOLUTION LOW TEMPERATURE SOLID-STATE NUCLEAR MAGNETIC RESONANCE PROBE
Document Type and Number:
WIPO Patent Application WO2005101949
Kind Code:
A3
Abstract:
This invention relates to an nuclear magnetic resonance (NMR) probe, which enables registering high resolution NMR double resonance spectra in powder samples by high-speed magic angle spinning at low temperatures. The idea of rotating device used in the design is based on using a small-diameter rotor which is placed in a helium gas flowthrough cryostat, ensuring low temperatures. The spinning of the rotor takes place as a result of gas flow directed to the gas bearings supported turbine. New is the use of an effective heat exchanger for cooling down the bearing and turbine gas.
