Resumen de Design and assessment of a low-frequency magnetic measurement system for eLISA
The primary purpose of this thesis is the design, development and validation of a system capable of measuring magnetic field with low-noise conditions at sub-millihertz frequencies. Such instrument is conceived as a part of a space mission concept for a gravitational-wave observatory called eLISA (evolved Laser Interferometer Space Antenna). In addition, the work of this thesis is also well-suited for use in magnetically sensitive fundamental physics experiments requiring long integration time, such as high-precision measurement of the weak equivalence principle using space atom interferometry. To this end, the baseline design of the instrument is also foreseen to monitor the environmental magnetic field in a proposed mission concept involving space atom-interferometric measurements, known as STE-QUEST (Space-Time Explorer and Quantum Equivalence Principle Space Test).
