magnetic gradient

An MRI term for the degree and direction of the linear rate of change of a magnetic field in space, which is one of three linear magnetisation waveforms superimposed on the main magnetic field at specific times within a pulse sequence to select the imaging region or provide necessary spatial localising information.

The potential for significantly higher velocities can be obtained with stronger magnetic fields and more precise shaping of the magnetic field along the axis for a greater magnetic gradient. Designing an ECR chamber so that ions will be generated in areas contributing to higher velocities will improve performance.
