03549 IUPAC Gold Book - linear electron accelerator 10.1351/goldbook.L03549 L03549 current 1 An evacuated metal tube in which electrons pass through a series of small gaps (usually in the form of cavity resonators in the high frequency range) so arranged and spaced that, at a specific excitation frequency, the stream of electrons on passing through successive gaps gains additional energy from the electric field in each gap.
