ABSTRACT:
An arrangement enables the frequency variation of a resonant element (an accelerating section for example) to be followed in dependence upon its temperature and the frequency of the hyperfrequency generator G feeding this resonant element Q to be controlled in dependence upon the frequency variations thereof. The arrangement comprises at least one reference cavity C associated with means for allowing the circulation of cooling fluid along the walls of said reference cavity and with heat supply for bringing it, at any instant, to the temperature of the resonant element Q, means for measuring the amplitude variation .DELTA.a of the signal corresponding to the frequency variation of said reference cavity C in terms of its temperature variation and a frequency variation system controlled by a signal proportional to the amplitude variation .DELTA.a, for modifying the operating frequency of the generator G. This arrangement makes it possible to improve the performance of medical accelerators of which the thermal time constant is considerable in relation to their short operating time.
