isotron|ˈaɪsəʊtrɒn|
[f. iso- (repr. isotope) + -tron.]
A machine for separating isotopes emitted as ions from an extended source by accelerating them by means of a varying electric field, which causes ions of like mass to bunch together, and applying a transverse radio-frequency field synchronized with the arrival of the bunches, so that the ions are deflected by an amount dependent on their mass.
1945H. D. Smyth Gen. Acct. Devel. Atomic Energy Mil. Purposes xi. 112 The objective..shifted to the effecting of large-scale separation of uranium isotopes by electromagnetic methods... Of the many electromagnetic schemes suggested, three soon were recognized as being the most promising: the ‘calutron’ mass separator, the magnetron-type separator.., and the ‘isotron’ method of ‘bunching’ a beam of ions. Ibid. 118 The device which resulted from Wilson's idea was given the deliberately meaningless name ‘isotron’. 1946Electronic Engin. XVIII. 153/3 Another method, dispensing altogether with a magnetic field, makes use of the klystron bunching principle and the device has been called the isotron. Ibid., It is understood from publications on the subject that the isotron method has not yet been fully developed. |
