چکیده

The contribution gives results of the theoretical analysis of the noise properties of the RF magnetic field receivers using the Superconducting Quantum Magnetometer (SQM) for NMR systems with the low magnetic field (Low-Field-NMR). The relation for the equivalent spectral sensitivity of the magnetic induction of the receiver, which covers the influence of the intrinsic noise of SQM, antenna system resistance loss components, the influence of measured sample and their noise temperatures, is given.

High Temperature Superconducting Radio Frequency Coils for Nmr Spectroscopy and Magnetic Resonance Imaging

High-temperature superconductivity has a significant opportunity to improve the performance of nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) systems. The low rf losses and compact size of superconducting coils allow them to improve the signal-to-noise ratio in applications where the system noise dominates that of the sample under study. These improvements tr...

High-resolution two-field nuclear magnetic resonance spectroscopy.

Nuclear magnetic resonance (NMR) is a ubiquitous branch of spectroscopy that can explore matter at the scale of an atom. Significant improvements in sensitivity and resolution have been driven by a steady increase of static magnetic field strengths. However, some properties of nuclei may be more favourable at low magnetic fields. For example, transverse relaxation due to chemical shift anisotro...

Three-dimensional calculations of the magnetic fields in a finite superconducting hollow cylinder in an applied axial magnetic field

In this study, a set of self-consistent coupled-integral equations for the local magnetic flux and current distributions in a finite superconducting hollow cylinder under an axial magnetic field has been directly derived by using the Biot-Savart law within the framework of the critical-state model. The equations were first solved numerically in the three-dimensional space before obtaining the h...

FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects

Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
