The transition radiation faculae on the rear side of a 20m thick target Ta was a smooth round structure with the center brighter than the periphery, indicating incoherent transition radiation and coherent transition radiation, which is close to the results of the theoretical simulations. For a 100m thick target Ta, the faculae was a star-structure and became smaller, which resembles a star-structure of the energetic proton emission. For a 10μm Ta+10m Cu+5m Ta composite target, the faculae was a ring structure and became bigger and non-uniform, looked like two apart faculae.
