Phys. Rev. ST Accel. Beams 12, 071001 (2009) [7 pages]Observation of focusing effect in optical transition and diffraction radiation generated from a spherical target
For the first time the focusing effect in optical transition and diffraction radiation generated by 1.28 GeV electrons in a tilted spherical target has been observed experimentally. A comparison of detected as well as simulated radiation spatial distributions produced by a flat and a spherical target has been made. It is shown that the application of such targets has allowed us to increase the radiation spectral-spatial density at the target focus without applying any additional focusing devices.
