I’m working to build and test magnetometers that can measure magnetic fields in the upper ionosphere, to better understand turbulence, electron precipitation, and Alfvén waves. These magnetometers have been used on balloons and suborbital rockets, meaning we have a good understanding of the sensor’s performance on short-time scales. In the future, we are targeting a long-duration multi-year application, such as a space weather monitoring instrument at the first Lagrangian point between Earth and the Sun. We would greatly benefit from knowing the performance of our magnetometers over longer durations of time. Testing a magnetometer for several days to a few weeks would help better define the limits of these devices and make known where improvements can be made. An important step to this future project is knowing the limits of our sensors, and how they vary over time. My project is to better understand the characterization and stability of our mini-T magnetometers. With the support of this grant, I would go to Goddard Space Flight Center and test our sensor in a high-grade facility for a longer duration than previous missions, to further strengthen and inform the short-term testing we do at the University of Iowa. A multi-week calibration at the GSFC facility would help us qualify our instrument design for long-term space weather forecasting applications.
