Zales Nelson Ecton (April 1, 1898 – March 3, 1961) was a Republican United States senator from Montana, having served from 1947 to 1953.
Ecton was born in Weldon, Decatur County, Iowa. He moved with his family to Gallatin County, Montana, when he was nine years old. He attended the Gallatin County public schools, the then Montana State College (later Montana State University) at Bozeman and the University of Chicago law school. In 1921, he became a rancher and gained interests in grain and livestock.
Entering politics, he was a member of the Montana state House from 1933 to 1937 and the Montana state senate from 1937 to 1946. In 1946, he ran for the Montana United States Senate seat which was being vacated by Democrat Burton K. Wheeler, who had lost the Democratic primary.
As part of the Republican takeover of the Senate in 1946, Ecton defeated Democratic state Supreme Court Justice Leif Erickson by a vote of 54% to 46%. He served in the Senate for one term, having been narrowly defeated for reelection in 1952 by U.S. Representative Mike Mansfield, a Democratic college professor and Far Eastern expert. Ecton resumed his ranching business until his death in Bozeman.
Ecton may refer to:
Ectons are explosive electron emissions observed as individual packets or avalanches of electrons, occurring as microexplosions at the cathode. The electron current in an ecton starts flowing as a result of overheating of the metal cathode because of the high energy density (104Jg−1), and stops when the emission zone cools off.
Ectons occur in plasma-involving phenomena, such as: electrical discharges in vacuum, cathode spots of vacuum arcs, volumetric discharges in gases, pseudosparks, coronas, unipolar arcs, etc.
An ecton consists of individual portions of electrons (1011– 1012 particles). The formation time is of the order of nanoseconds.
