The National Institute for Standards and Technology uses a solenoid to keep their spin filters polarized. Transverse magnetic gradients are causing the spin filter to depolarize faster. I was tasked with measuring very small transverse gradients using Hall Effect Sensors, so that researchers could make adjustments to extend the lifetime of the spin filter. • Analyzed the noise and drift of Hall Effect Sensors, proving it was possible to measure magnetic gradients down to a few mG/cm. • Developed a method to efficiently and accurately calibrate Hall Effect Sensors. • Built a magnetic gradiometer prototype and measured the underlying components of • magnetic gradients as small as 10 mG/cm.
