Abstract :
Spectral distributions of X-ray resonance transition radiation (RTR) generated by 300, 500 and 700 MeV electrons in a target consisting of as many as 125 Be foils have been measured. When the electron energy increased from 500 to 700 MeV, a rapid growth of photon yield was observed in the spectral region h̵ω = 5–30 keV, thus confirming the threshold effect of the on-set of the first harmonic of RTR.
