Abstract

The results of investigations of solar-blind image converter tubes (ICTs), sensitive in the ultraviolet spectral range are presented. Photocathodes sensitive layers of the ICT are based on boron-doped polycrystalline diamond films were grown up on sapphire substrates for the first time. Spectral range of the ICT sensitivity is 180…250 nm, the threshold sensitivity value without the electron flow multiplier ~ 10-9 W/Hz0.5 and spectral sensitivity ~ 12 - 15 mA/W.
