rce can be estimated by superimposing the reconstructed dipoles to an equivalent dipole and comparing the corresponding volume with the sphere which would be related to the equivalent dipole. The deviation of these volumes can be taken as a criterion for non-dipolarity of sources.978-1-4612-7066-9978-1-4612-1260-7作者: Landlocked 時間: 2025-3-22 02:03

Thomas Ahne,Wolfgang Mayer Scarnatoe applied magnetic field. The resulting signal from the FLL is proportional to the change in the applied magnetic field. The FLL then provides the SQUID the ability to track changes in the applied field within a well defined linear range provided the slew rate or dynamic range of the SQUID and FLL system are not exceeded.作者: figment 時間: 2025-3-27 11:00 作者: Ingrained 時間: 2025-3-27 15:42

Magnetic Field Error of a Current Dipole in a Superconducting Shieldld might give a considerable change to the magnetic field because the superconducting shield has a small dimension of 90cm in diameter. This also might result in localization errors of the current dipole. In this paper we evaluate the magnetic field of the image and estimate the contribution of the image field to the field of the current dipole.作者: Processes 時間: 2025-3-31 11:40
