Title: The Effects of Radiation and Thermal Stability of Sm-Co High Temperature Magnets For High Power Ion Propulsion
Agency: NASA
Contract: NNC04CB01C
Award Amount: $94,444.00


Since high temperature Sm-Co based magnets were developed, a number of new applications have been introduced. NASA?s Xe+ ion propulsion engine used in Deep Space I (DS-I) is a prime example. The magnets with coating perform well at temperatures up to 550?C. Magnets without coating perform well in the current 10 kW Xe+ ion engines in the vacuum which exists in space and at temperatures up to 400?C. Additional challenges are expected in the missions NASA is planning. The new missions, with higher-powered engines, include travel toward the sun, to Jupiter, and planets beyond. In these higher-powered engines (> 10 kW) temperatures are expected to reach 550?C in vacuum to ~10-5 Torr. Technical data of the high temperature Sm-Co in the conditions of the NASA?s new mission are needed. This program proposes to study the effects of radiation on physical and magnetic properties, and the thermal stability and its improvement, in vacuum at temperature up to 550?C, of Sm-Co high temperature magnets. Based on the results of this work, improvements to Sm-Co magnets will be made to enhance the performance of high power Xe+ ion propulsion engines.
