<p>A magnetron (1) is tuned by a co-axial transmission line (21) co-axial with the axis of the magnetron and a radial transmission line (19) linking the co-axial line to a plurality of sampling points (16) symmetrically positioned on the end of the magnetron. A fraction of the R.F. power in the magnetron passes into the transmission lines and vice versa, so by altering the resonant frequency of the transmission lines the frequency of the RF power in the magnetron can be controlled.</p> |
