| dbo:abstract | جون مادي (بالإنجليزية: John Madey) (و. 1943 – 2016 م) هو فيزيائي من الولايات المتحدة الأمريكية . (ar) Julius Michael John Madey (* 1943; † 5. Juli 2016) war ein US-amerikanischer Physiker. Er leitete das Team, das den ersten Freie-Elektronen-Laser (FEL) baute. Madey studierte am Caltech, mit einem Bachelor-Abschluss in Physik bei Alvin Tollestrup 1964. 1965 machte er dort seinen Master-Abschluss (formal in Elektrotechnik) beim Laser-Pionier Amnon Yariv. 1971 wurde er an der Stanford University bei William Fairbank Sr. promoviert, wobei er eine Quelle thermischer Positronen entwickelte. Als Student arbeitete er im Sommer am Brookhaven National Laboratory beim Aufbau des AGS Synchrotrons. John Madey war auch Funkamateur. Nach seiner Promotion war er ab 1971 am W. W. Hansen Laboratory in Stanford, wo er den Freien Elektronenlaser erfand und mit seinem Team baute. 1986 erhielt er eine Forschungsprofessur in der Fakultät für Elektrotechnik der Stanford University. 1989 ging er mit seinem FEL-Labor von Stanford an die Duke University, wo er ein Projekt leitete, das einen FEL in einem Speicherring entwickelte, und Direktor des FEL-Labors war. Er trennte sich 1997 im Streit von der Duke University. Es kam auch zu einem Rechtsstreit, da die Duke University Patente von Madey weiter verwendete. 2002 siegte Madey vor dem Berufungsgericht, was auch Auswirkungen in der US-Forschungsszene hatte, da das Gericht die bis dahin übliche Praxis unterband, solche patentgeschützten Erfindungen für nicht-kommerzielle Zwecke in der Grundlagenforschung zu verwenden. Ab 1998 war Madey Professor für Physik an der University of Hawaii. Hier wendete er FEL-Laser zur Fernerkundung an. 1989 erhielt er die Ballantine Medal des Franklin Institute. Ihm wurde für 2012 der Robert R. Wilson Prize zugesprochen. 2016 erhielt er den Willis E. Lamb Award. Nach seinem Bruder Jules Madey benannt ist der Gebirgskamm Madey Ridge in der Antarktis. (de) John M. J. Madey (28 February 1943 - 5 July 2016) was a professor of Physics at the University of Hawaii at Manoa, a former director of the Free Electron Laser Laboratory at Duke University, and formerly a professor (research) at Stanford University. He is best known for his development of the free-electron laser (FEL) at Stanford University in the 1970s. Raised in Clark, New Jersey, Madey and his older brother Jules took an early interest in ham radio. In 1956, when John was 13 and Jules was 16, they began relaying communications from the south pole to families and friends in the United States. While an undergraduate at the California Institute of Technology, he had a discussion where the question came up as to whether or not it was possible to enhance the transition rate for bremsstrahlung through stimulated emission. Madey received a BS degree in Physics and a MS degree in Quantum Electronics from the California Institute of Technology in 1964 and 1965. He continued thinking about the stimulated emission question while working on his doctoral degree at Stanford, when he invented the free-electron laser. He was awarded a PhD in 1970, and appointed as Professor (Research) of Electrical Engineering in 1986. Stanford University refused to patent this idea so Madey filed for a patent on his own. In the following years, he developed an innovative laser research program which was highly regarded in the scientific community. An opportunity arose for Madey to leave Stanford, taking a tenured position at the Physics Department of Duke University, which Madey accepted in 1988, moving his FEL research laboratory with him in 1989. This laboratory contained substantial equipment which required Duke to build an addition to its physics building to house the lab. In addition, while at Stanford, Madey had obtained sole ownership of two patents practiced by some of the equipment in the FEL lab. (en) Джон Майкл Джулиус Мэйди (англ.
