Thermal-Hydraulic Analysis of Rhodotron Accelerator Cavity

Electron accelerators use electric and magnetic fields to accelerate and control charged particles to the close proximity of the speed of light. The results of the experimental test performed on the Yazd Rhodotron cavity cooling system as well as the relevant numerical analysis carried out by the ANSYS 12 code are presented. It was found that the numerical prediction for the cavity wall temperature under normal operating condition was in reasonable agreement with the corresponding experimental result. In addition, due to the blockage effect of the cooling channels, the cavity wall temperature was higher than normal operating conditions.
