Abstract	Study on the thermal process in repetitively operated electron beam collectors of relativistic backward wave oscillators is proposed. Using Monte Carlo method, the energy deposition of the beam was calculated. With energy deposition as the internal heat generation, numerical model of thermal process in collectors was estimated in finite element method. Temperature development was obtained and compared to the results of the experiment, which was performed with thermocouples. The heating process is adiabatic in some extent for the very short pulse, but the cooling is quite time-consuming on the contrary. Thus, temperature rises in sharp waveforms and can be extremely high, which is quite different from previous studies. Differences between simulation and experiment are discussed, including cooling boundary condition simplification of the numerical model and some drawbacks of the measuring system. The continuing work is also presented at last.
