Target Field Design of Surface Permanent Magnets
Peter J. Hobson, Chris Morley, Alister Davis +2
We present a target field approach to analytically design magnetic fields using permanent magnets. We assume that their magnetisation is bound to a two-dimensional surface and is c…
Bi-planar magnetic stabilisation coils for an inertial sensor based on atom interferometry
A. Davis, P. J. Hobson, T. X. Smith +4
Inertial sensors that measure the acceleration of ultracold atoms promise unrivalled accuracy compared to classical equivalents. However, atomic systems are sensitive to various pe…
Designing optimal loop, saddle, and ellipse-based magnetic coils by spherical harmonic mapping
Peter James Hobson, Noah Louis Hardwicke, Alister Davis +8
Adaptable, low-cost, coils designed by carefully selecting the arrangements and geometries of simple primitive units are used to generate magnetic fields for diverse applications.…
Benchtop magnetic shielding for benchmarking atomic magnetometers
P. J. Hobson, N. Holmes, P. Patel +14
Here, a benchtop hybrid magnetic shield containing four mumetal cylinders and nine internal flexible printed circuit boards is designed, constructed, tested, and operated. The shie…
Bespoke magnetic field design for a magnetically shielded cold atom interferometer
P. J. Hobson, J. Vovrosh, B. Stray +10
Quantum sensors based on cold atoms are being developed which produce measurements of unprecedented accuracy. Due to shifts in atomic energy levels, quantum sensors often have stri…
Magnetic Field Design in a Cylindrical High-Permeability Shield: The Combination of Simple Building Blocks and a Genetic Algorithm
M. Packer, P. J. Hobson, A. Davis +7
Magnetically-sensitive experiments and newly-developed quantum technologies with integrated high-permeability magnetic shields require increasing control of their magnetic field en…
Planar Coil Optimization in a Magnetically Shielded Cylinder
M. Packer, P. J. Hobson, N. Holmes +5
Hybrid magnetic shields with both active field generating components and high-permeability magnetic shielding are increasingly needed for a variety of technologies and experiments…
Optimal Inverse Design of Magnetic Field Profiles in a Magnetically Shielded Cylinder
M. Packer, P. J. Hobson, N. Holmes +5
Magnetic shields that use both active and passive components to enable the generation of a tailored low-field environment are required for many applications in science, engineering…
