Novel Magnetometer for High Energy Physics, Fusion, and Electric Utility Applications

72900-A novel magnetometer is needed for the measurement of various types of magnet systems and electric utility equipment including dipoles, quadrupoles, fusion magnets, electrical buss bars, motor, generators, and fault current limiters. This project will develop a novel magnetometer that has the simplicity, sensitivity, and versatility to address a wide variety of measurement configurations for academic, industrial, and military applications. The magnetometer provides a unique three-dimensional integrated measurement capability not found in similar types of systems. Phase I demonstrated the viability of the magnetometer and addressed concerns regarding temperature fluctutaions, noise, and end effects in accelerator magnets. The sensitivity and accuracy of the device in parallel B-fields was demonstrated, and measurement signals in perpendicular B-fields were conclusively observed. In Phase II, the prototype magnetomer will be upgraded to incorportate improvements in both signal strength and noise reduction. Tests will be conducted in conjunction with Fermi National Accelerator Laboratory with respect to accelerator type magnets and with Lawrence Berkeley Laboratory with respect to industrial magnets systems. Commercial Applications and Other Benefits as described by awardee: Commercial applications for the new magnetometer should include fusion magnets systems and electric utility diagnostic equipment.
