A linear magnetic field scan driver [PDF]
Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2009 AbstractA linear magnetic field scan driver was developed to provide a rapidly scanning magnetic field for use in electron paramagnetic resonance (EPR) spectroscopy. The driver consists of two parts: a digitally synthesized ramp waveform generator and a power amplifier to drive the magnetic field coils.
