Problems solved by technology

Due to the outstanding polarization enhancement effect of DNP, improving the detection sensitivity of NMR through DNP technology is a research hotspot in the field of NMR and MRI at present. Bottlenecks in DNP-related research
[0004] The DNP probe is a key component of the DNP system, and its performance index is directly related to the DNP enhancement effect. However, there are few domestic reports on the design and development of DNP probes, and most of the research is in the low frequency band, and the resonance peaks of organic molecules are mostly in the The terahertz frequency band, so the development of the DNP system in the terahertz frequency band is urgent, and the dual-frequency terahertz DNP probe system as its key component is even more urgent

Abstract

The invention discloses a double-frequency DNP probe system for a dynamic nuclear polarization system and an assembling method thereof, and belongs to the technical field of nuclear magnetic resonance. A first bottom plate and a second bottom plate are mainly disposed for cooperative use to the inner wall surface of an inner hole in a solenoid for radio frequency resonance to form a Terahertz resonant cavity, thus realizing dual resonance of a radio frequency band and a Terahertz frequency band, effectively reducing the volume of the DNP probe and having good applicability.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance, in particular to a dual-frequency DNP probe system for a dynamic nuclear polarization system and an assembly method thereof. Background technique [0002] With the development of nuclear magnetic resonance technology, nuclear magnetic resonance (nuclear magnetic resonance, NMR) technology has been widely used as an important analysis method in the fields of physics, chemistry, biology and medicine. However, compared with other spectroscopy methods, an obvious disadvantage of NMR technology is that its detection sensitivity is very low. The magnetic resonance imaging (MRI) technology developed based on the NMR theory also faces the same problem. How to improve the detection sensitivity of NMR and MRI has always been the direction of efforts of researchers in the field of magnetic resonance. [0003] Although the nuclear polarization can be increased by increasing the magnetic ...
