For the first time the focusing effect of coherent transition radiation generated in a paraboloidal target by electrons with energy of 6.1 MeV has been observed experimentally. A comparison of the angular distribution of detected radiation was made for flat and paraboloidal targets under focusing and defocusing conditions. Using paraboloidal targets one can considerably increase the spectral-angular density of the radiation in the paraboloidal focus without any additional optical devices.
