The development of non-intercepting diagnostics for high charge density and high energy electron beams is one of the main challenge of beam instrumentation. Diffraction Radiation based diagnostics, being non-intercepting, are among the possible candidates for the measurements of beam properties for the new generation linacs. At the 1 GeV Sincrotrone Trieste linac, we are performing the first measurements of beam transverse parameters using Diffraction Radiation emitted by the electron beam passing through a 1 mm slit opened on a screen made of aluminium deposited on a silicon substrate. The analysis of the angular distribution of the Diffraction Radiation for a given wavelength, slit aperture and beam energy gives information about the beam size and its angular divergence. |
