The paper deals with thermal management of RF-section of 250kW CW C-band Klystron. The thermal analysis of RF section has been done using ANSYS 11.0 (multi-physics) code. The thermal analysis calculates the temperature distribution and related thermal quantities in a system or component. The basis for thermal analysis in ANSYS is a heat balance equation obtained from the principle of conservation of energy. The input parameters used in thermal simulation are geometry of components, heat flux, heat transfer coefficient and output parameter is temperature profile of RF section. The RF section analysed using Poisson’s Superfish, AJ-Disk and Magic 2D soft-wares to observe the electron-beam interaction in the RF-section of the Klystron. The results of these simulations i.e. R/Q, Q and the voltage across the gap of the cavity are then used to calculate heat dissipated in the RF section.
