Abstract: Ultraviolet solar-blind electron-optical converters with photocathode sensor layers made of polycrystalline boron-doped diamond films, which were for the first time grown on sapphire, are studied. The spectral sensitivity range of the obtained converters is 180–250 nm, the threshold sensitivity without the electron flux multiplier is no worse than $\sim$10$^{-9}$ W/Hz$^{0.5}$, and the spectral sensitivity is 12–15 mA/W.

Keywords: diamond photocathode, vacuum ultraviolet range, electron-optical converter, electron flux multiplier.
