Thermal design of the collector in high power klystron plays a crucial role in overall design of klystron. Spent electron beam, after giving a part of its kinetic energy to RF fields, strikes on the inner surface of collector and dissipates its remaining energy in the form of the heat. In case of high average power tubes, the energy deposited on the collector may damage the collector if the heat is not removed efficiently. The overall dimensions and the shape of the collector depend on the operating voltage and the average power of the beam. This paper presents the thermal design of the collector of a 250 KW C band Klystron under development. Thermal simulation has been done by using ANSYS 11.0 (multi-physics). The outer surface of the collector has been grooved to increase cooling. Design results are presented for water-cooling with different flow rates and channel dimensions.
