Abstract: A method for correcting motion-effects from a downhole measurement includes, in one embodiment, determining relative motion of a downhole logging tool for a given logging operation in a borehole formed in an earth formation, determining a motion induced signal decay (MID) based upon the determined relative motion, determining a motion-effect inversion kernel (MEK) based upon the determined MID, using the downhole logging tool to acquire measurements that are affected by motion of the downhole logging tool during the logging operation, and using the MEK to process the acquired motion-affected measurements to obtain motion-corrected data. Corresponding systems, devices, and apparatuses are also disclosed herein.

Abstract: Described herein are a magnetic resonance probe and a NMR, MRI, or EPR apparatus including the same. The magnetic resonance probe includes a conductor electrically coupled to the resonator and configured to transmit and receive electromagnetic radiation to and from a sample, wherein the conductor includes one or more cascaded narrowed regions along its longitudinal dimension and a slot within one of the one or more cascaded narrowed regions; and an electrical circuit coupled to the conductor and the resonator.
