The high frequency power provided by high-voltage modulator designed with vacuum tubes, serves to accelerate the electron beam in the section formed by copper cavities. Some of the remaining power is dissipated in the cavities and metallic components of the modulator such as PFN, tubes, power supplies.
These components are cooled by a circulation of water. The importance of regulating the temperature of the cooling water is to maintain the same temperature in the cavities and in highpowercomponents. Thisisanimportantfactorinmaintainingfrequencytuning.
The design and sizing of the cooling system must take into account the influence of ambient temperature, the nature of the water used, the power generated by the accelerator and other important factors.
Based on a history of our Linac accelerator, this work will focus on the cooling problems that may affect reliability of radiofrequency modulator installed hot-cavity accelerator.
