A simulated 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.

Hall probe simulator circuit

Various systems and methods for detecting electron spins using electron paramagnetic resonance are described. An excitation signal generator configured to generate an excitation signal of varying amplitude and phase as compared to a reference signal may be present. A crossed-loop resonator configured to isolate a detection signal produced by the excitation signal exciting an object with a magnetic field may also be present. Further, a detection device configured to detect electron spins of the object using the detection signal isolated by the crossed-loop resonator may be present.

EPR methods and systems

Embodiments of the invention are directed toward a crossed-loop electron paramagnetic resonance resonator comprising a first resonator having a first resonator axis; and a second resonator having a second resonator axis. The first resonator axis and the second resonator axis can be substantially perpendicular. Either or both the first resonator and the second resonator can be a ribbon resonator having a plurality of metallic ribbons formed in a loop. Each metallic ribbon can include a central axis. The plurality of metallic ribbons can be arranged parallel relative one to another.

Crossed-loop resonators

Various systems and methods for detecting electron spins using electron paramagnetic resonance are described. An excitation signal generator configured to generate an excitation signal of varying amplitude and phase as compared to a reference signal may be present. A crossed loop resonator configured to isolate a detection signal produced by the excitation signal exciting an object with a magnetic field may also be preset. Further, a detection device configured to detect electron spins of the object using the detection signal isolated by the crossed loop resonator may be present.
