Educated at McGill and London, Henderson joined the NRC in 1933 where he worked on the effects of the ionosphere on radio signals and the Direction Finder invented by A.G.L. McNaughton and W.A. Steel. In 1939, he became involved with the secret radar development and is particularly recognized for his leadership role in this technology during World War II, laying the foundations for radar research and manufacture in Canada. Henderson returned to the NRC after RCAF and diplomatic service from 1942–47 and became head of its electricity section, which built several cesium atomic clocks. == Early years == Henderson was born in Montréal, Canada. He received the B.S. and M.S. degrees in engineering physics from McGill University, and then went to England, where he studied under Professor Edward Victor Appleton. He received the Ph.D. degree in physics from King's College London in 1932, and followed this with post-doctoral studies at the Sorbonne in Paris and the Technische Hochschule in Munich. In 1933, he joined the NRC in Ottawa as chief of the Radio Section. Over the next several years, his work included the building of a highly advanced radio direction-finding set that used a CRT for its display; this was installed in Nova Scotia in 1938. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「John Tasker Henderson」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
