    "abstract": "For short, high-intensity electron bunches, alkali-tellurides have proved to\nbe a reliable photo-cathode material. Measurements of lifetimes in an RF gun of\nthe CLIC Test Facility II at field strengths greater than 100 MV/m are\npresented. Before and after using them in this gun, the spectral response of\nthe Cs-Te and Rb-Te cathodes were determined with the help of an optical\nparametric oscillator. The behaviour of both materials can be described by\nSpicer\u0027s 3-step model. Whereas during the use the threshold for photo-emission\nin Cs-Te was shifted to higher photon energies, that of Rb-Te did not change.\nOur latest investigations on the stoichiometric ratio of the components are\nshown. The preparation of the photo-cathodes was monitored with 320 nm\nwavelength light, with the aim of improving the measurement sensitivity. The\nlatest results on the protection of Cs-Te cathode surfaces with CsBr against\npollution are summarized. New investigations on high mean current production\nare presented.",
