The Magnetic Field Gradiometer

open access: yes, 1983
Final Technical Report No. E723-1 This report has two principal goals: First, to present a general review of magnetic field gradiometers and, second, to provide new data concerning these gradiometers, including new information about their response to magnetic dipole fields. A system of nomenclature is introduced that is consistent with the mathematical

Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

Gradiometry and gravitomagnetic field detection [PDF]

open access: yes, 1989
Gravitomagnetism was apparently first introduced into physics about 120 years ago when major developments in electrodynamics and the strong similarity between Coulomb's law of electricity and Newton's law of gravity led to the hypothesis that mass ...

The Layout and Size of an Early Pre‐Pottery Neolithic B Small Settlement Revealed by Geophysical Prospection at Harbetsuvan Tepesi in Southeastern Anatolia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT In Upper Mesopotamia, the transition from the Pre‐Pottery Neolithic A (PPNA) to Pre‐Pottery Neolithic B (PPNB) period, ca. 10 800–10 600 cal. BP, is marked by a series of changes in chipped stone industries, architectural forms, symbolic objects, regional distribution of settlements and long‐distance exchange networks among others.

Improved Biomagnetic Signal-To-Noise Ratio and Source Localization Using Optically Pumped Magnetometers with Synthetic Gradiometers

open access: yesBrain Sciences, 2023
Optically pumped magnetometers (OPMs) can capture brain activity but are susceptible to magnetic noise. The objective of this study was to evaluate a novel methodology used to reduce magnetic noise in OPM measurements.
