Emission angles for soft x-ray coherent transition radiation

Abstract

Emission angles for both coherent and incoherent transition radiation in the soft x ray region were measured. The results clearly show that coherent transition radiation produces larger emission angles at high beam energies than does incoherent radiation. These results allow the possibility of using coherent transition to measure higher electron beam energies than are possible using incoherent radiation approximations. The measured emission angle magnitudes are compared to theoretical values obtained using computer simulation. Differences are noted and possible sources of error are cited
