The RF system of the CERN synchrocyclotron, the main components of which are the resonator (dee system) and the RF generator, was developed and built by Philips Eindhoven in cooperation with CERN engineers. On the basis of theoretical considerations and experiments with three different models, a resonator was finally built whose resonant frequency is swept through the required range from 29 to 16.5 Mc by means of a capacitance variation from 256 to 2580 pF of the modulation capacitor (tuning fork). The construction of the resonator, and the measures taken to avoid mechanical strains, are broadly described. The oscillator operates as a "flywheel" circuit, the control voItage for the oscillator valve (water-cooled 100 kw triode TBW 12/100) being taken from a feedback circuit in the oscillator, although the resonator - which is connected at one point - still governs the frequency, owing to its high Q. With this circuit, little trouble is experienced from unwanted modes of oscillation in the RF system. (auth)
