1. FOR THE DUSTY PLASMA LABORATORY DR. BRADLEY WILL MANAGE EXPERIMENTS ON LEVITATE MICRONSIZED DUST GRAINS THAT DETERMINE 1) THE VARIATION OF CHARGE ON A GRAIN WHILE IN ENVIRONMENTS SIMILAR TO THOSE FOUND ON OTHER SOLAR SYSTEM BODIES SUCH AS MARS 2) THE GROWTH RATE AND MORPHOLOGICAL CHANGES OF THE GRAINS WHEN IN CONTACT WITH DIFFERENT GASES AT TEMPERATURES RANGING FROM THE INNER THROUGH THE OUTER SOLAR SYSTEM 3) THE MAXIMUM CHARGE A GRAIN OF A PARTICULAR SIZE AND COMPOSITION MAY OBTAIN. 2. FOR THE IMAGING X-RAY POLARIMETRY EXPLORER (IXPE) DR. BRADLEY WILL ASSIST IN DETECTOR TESTING AND CALIBRATION BY 1) HELPING TO BUILD AN X-RAY POLARIZATION SOURCE THAT OPERATES OVER A RANGE OF DISCRETE ENERGY LEVELS THAT ARE IN THE OPERATIONAL RANGE OF IXPE DETECTORS 2) PERFORM A SERIES OF TESTS ON THE IXPE DETECTORS USING THE X-RAY POLARIZATION SOURCE TO VALIDATE THE PERFORMANCE CHARACTERISTICS OF THE DETECTORS AND 3) ASSIST WITH CALIBRATION EXPERIMENTS ON THE INTEGRATED IXPE INSTRUMENT. 3. DEVELOPMENT OF A SIMULATED GPS TRANSMITTER IN MATLAB SIMULINK TO 1) DEVELOP ALGORITHMS TO RETRIEVE CARRIER WAVE THAT HAS NOISE ADDED AND 2) INFORM A DESIGN THAT CAN BE USED BY OTHERS TO BUILD A PROTOTYPE GPS TRANSMITTER THAT CAN BE USED ON SPACECRAFT IN EARTH ORBIT THAT ARE AFFECTED BY NOISE FROM THE IONOSPHERE. THIS PROJECT IS LED BY DR. LINDA KRAUSE.
