Brief Biogrophy

Don Reames received his A. B. and Ph. D. degrees in physics from the University of California at Berkeley in 1958 and 1964, respectively. He applied this early background in nuclear physics to his work in experimental astrophysics at Goddard Space Flight Center since 1964. His early work involved the S9 Cosmic Ray Experiment flown on the Gemini XI mission and sounding rockets flown from Ft. Churchill. He subsequently worked with experiments on the ISEE-3, IMP-8, Helios 1 and 2, and Wind spacecraft. As a Co-I on the EPACT experiment on the Wind spacecraft, he was responsible for the design and con-struction of the Low Energy Matrix Telescope (LEMT). He is also a Co-I on IMPACT experiment for the STEREO mission. He has studied the physics of particle acceleration in a variety of sites throughout the heliosphere and the relationship of these particles to solar flares, shock waves, CMEs and to the radio, X-ray, and gamma-ray emission that they particles produce. This work has resulted in over 100 papers in the refereed scientific literature. Don Reames retired from the Civil Service in 2003 to continue in an Emeritus position at Goddard.
