M .: “Sovetskoe radio” , 1974, p .224 ( in Russian ).In operation the possibility of generation of UWB signal was researched at excitement of a helical antenna by a high-current relativistic bundle of nanosecond duration. The experiments were conducted on a high-current relativistic accelerator REB "Темр-А" with parameters: Eb ~ 0,5 .1,0 МeV, Ib ~ 5 -10 кА, duration of a ~15nс., at the value of a leading edge ~ 1...2 nс. The calculation data of a helical antenna and parameters of a generated UWB signal are reducedenENERGIZATION, HELICAL ANTENNA, HIGH-CURRENT REBArticle
