Magnetic Field Mapping in the BESIII Solenoid
IEEE Transactions on Applied Superconductivity, 2010The Beijing Spectrometer III (BESIII) superconducting solenoid magnet, which is running in the Beijing Electron Positron Collider II (BEPC-II), is an important part of BESIII and provides a 1 Tesla field in the main drift chamber. A 3-D mapping device with three 3-D probes was fabricated to measure the field components of , and .

Magnetic Resonance in Medicine, 1988
AbstractHomogeneous radiofrequency magnetic fields are necessary for production of high‐quality magnetic images and for most forms of magnetic resonance spectroscopy. It is often convenient to map the radiofrequency homogeneity associated with a resonant device by measuring the magnetic image intensity of an aqueous phantom placed within the resonator.

Magnetic field mapping in NMR imaging
Magnetic Resonance Imaging, 1987The Hahn spin preparation sequence provides a practical means for rapid and sensitive mapping of magnetic field inhomogeneity in NMR imaging applications. Choice of the rf pulse delay times tau 1 and tau 2 as well as conditions and limitations on the proposed use of this sequence for chemical shift imaging are discussed.

Mapping the Local Bubble's Magnetic Field in 3D
2023We present a 3D map of magnetic field orientation on the surface of the Local Bubble. This map is the first of its kind to fully chart magnetic fields over an observed superbubble. Recent work mapping the 3D shape and dynamics of the Local Bubble has revealed that the formation of all young stars within 200 pc of the Sun was triggered by the Bubble's

Magnetic Field Mapping by Selective Equipotential Excitation
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006A new magnetic field mapping method in MRI is presented. This technique is ideal for severe inhomogeneities where plane warp cannot be ignored. The present study employs a ferromagnetic ball to create a perturbation within the imaged volume. The magnetic moment and position of the device are acquired experimentally with a new technique that excites ...

Field-Map Characterization From Magnetic Survey in High-Field Magnets
IEEE Transactions on Magnetics, 2016Quality checks to characterize the high-field magnets before final assembly are usually foreseen when high accuracy is required in the field map. This process may possibly include magnetic field measurements in regions adjacent to the coils, thus different from the target field areas.
