    The electron emission yield was measured for the impact of 3 keV electrons and 2 MeV H+ ions on Al as a function of target temperature. A strong influence of the surface morphology was found. For annealed samples a linear decrease of the yield was observed for increasing temperature. In the temperature range 50-440 °C the yield for electron impact decreased by 4%, for proton impact by 6%. In addition, the work function of Al was measured for 25 °C and for 440 °C. The dependence of the yield on the work function was investigated by Monte Carlo simulation of the electron emission process for electron and proton impact. The temperature dependence of the yield is discussed in terms of work function changes.
