  • Group of Gradient Magnetic Fields in NMR Experiments
  • Laboratory of NMR Methods
  • NMR Division


Personal Data:

Research Interests:

  • Generation of time-variable gradient pulses for NMR spectroscopy, tomography, and microscopy (since 1981). The problems to solve include:
    • Spectrometer pulse control.
    • Gradient sources.
    • Measurement of pulsed magnetic fields.
    • Development of the MULTIFID method and the NMR method of the instantaneous frequency with the selective excitation for the gradient magnetic field measurement.

  • Control circuits for decoupling in spectroscopy and for amplitude and phase modulation of RF pulses for tomography have been designed.

  • Experimental work for tomography. Using 80 MHz and 200 MHz spectrometers I tested the following methods:
    • Utilization of selective RF excitation pulses.
    • Spin echo and its symmetrical transformation.
    • Excitation of phase modulated RF pulses by pseudo-random noise.
    • Application of gradient fields.
    • Dynamic behaviour of pulsed magnetic fields.
    • NMR tomography (microscopy) including localization techniques.
    • Water suppression methods in the proton NMR spectroscopy.
    • 31P and 1H decoupling with adiabatic pulses.
