John Madey

from Wikipedia, the free encyclopedia

Julius Michael John Madey ( 1943 - July 5, 2016 ) was an American physicist . He led the team that built the first free electron laser (FEL).

Madey studied at Caltech , with a bachelor's degree in physics from Alvin Tollestrup in 1964. In 1965 he made his master's degree (formally in electrical engineering) from laser pioneer Amnon Yariv . In 1971 he received his PhD from Stanford University under William Fairbank Sr. , where he developed a source of thermal positrons. As a student he worked in the summer at Brookhaven National Laboratory building the AGS synchrotron . John Madey was also a radio amateur .

After receiving his doctorate, he went to the WW Hansen Laboratory in Stanford in 1971, where he invented the free electron laser and built it with his team. In 1986 he received a research professorship in the electrical engineering department at Stanford University . In 1989 he went to Duke University with his FEL laboratory from Stanford , where he led a project developing a FEL in a storage ring and was director of the FEL laboratory. He split up in 1997 in a dispute from Duke University. Litigation also ensued over the continued use of Madey's patents by Duke University. In 2002, Madey won the appeals court, which also had an impact on the US research scene, as the court prohibited the previously common practice of using such patented inventions for non-commercial purposes in basic research.

From 1998 Madey was Professor of Physics at the University of Hawaii . Here he used FEL lasers for remote sensing .

In 1989 he received the Ballantine Medal from the Franklin Institute. He was awarded the Robert R. Wilson Prize for 2012 . In 2016 he received the Willis E. Lamb Award . The Madey Ridge in Antarctica is named after his brother Jules Madey .
