Abstract content

A LED flasher has been developed for TUNKA-133 EAS Cherenkov detector. Blue ultra bright InGaN LED is used as a light source in the flasher. The flasher's driver based on a complementary pair of fast RF transistors. The light yield of the flasher is adjusted in a wide range from 0 to upt to 10**9 photons per pulse. The results of studies of the flasher's amplitude and timing parameters and their stabilities are presented.
