Abstract
A controlled-frequency arrangement for feeding a linear charged particle accelerator and enabling the power reflected by the accelerator toward the microwave generator feeding it to be minimized when the accelerator is loaded by the particle beam. The feeding arrangement comprises means for obtaining a continuous signal v of which the amplitude is proportional to the phase shift .DELTA..phi. which may exist between the microwave signal injected into the accelerator and the signal stored in the accelerator, and for comparing this signal v with a variable reference signal v.sub.4 to obtain an error signal v - v.sub.r which, when applied to a frequency controlling system, causes the frequency F of the microwave generator associated with the accelerator to be suitably varied, this variation in frequency .alpha.F enabling the phase shift .alpha..phi. to be eliminated.
