Abstract
HIGH-FREQUENCY oscillations produced in electrical discharges under the influence of a magnetic field have attracted considerable attention in recent years. In addition to their purely physical interest, they have proved of value to the engineer in the magnetron oscillator, a device which is quite closely related to the cyclotron, or proton accelerator, of Lawrence and Livingston. The secondary emission electron-multiplier of P. T. Farnsworth provides another example of a device in which oscillations can be produced by means of the co-operation of electric and magnetic fields; it differs from the magnetron in that the two fields are aligned instead of being approximately perpendicular.
