Betsy Ancker-Johnson EducationBetsy Ancker-Johnson attended Wellesley College and later a graduate school in Germany. In 1953, She received her Ph.D. in physics. It was always her dream to be a physicist.
Betsy Ancker-Johnson AchievementsAccording to the University of California Physics Department, "Betsy Ancker-Johnson's early contributions to the study of the instabilities that can occur in plasmas in solids, such as pinching (1963) and oscillatory behavior (1962), culminated in Betsy Ancker-Johnson's observation of microwave emission from an electron-hole plasma (1967). The latter is the first observation of microwave emission without the presence of an external field, but initiated only by the application of an external electric field. These non-equilibrium processes in solid state plasmas occur at higher plasma density than are usually studied in dilute gaseous plasmas."
