Abstract

Systems and methods are disclosed to simulate a Hall probe, provide EPR coil driver, and/or perform a time-domain full scan sinusoidal deconvolution of EPR signals. The simulated Hall probe can return a Hall Effect voltage from a coil current that creates a magnetic field within a coil magnet and the reference current that would be fed to an actual Hall probe. From these values, the Hall Effective voltage can be determined which can be used to determine the magnetic field flux, which can then be used to regulate the magnetic field. Embodiments of the invention also disclose a coil driver and a new technique for EPR deconvolution.
