Abstract

At CESTA, the 35 GHz experiment ONDINE I is in progress. The studies focus on intense electron beam creation with the Euphrosyne generator and its propagation to the wiggler by mean of a transmission line. The generator consists in a Marx generator, a pulse forming line and a diode using both thermoionic and cold cathodes. The diode has been adapted to the forming line at 36 Ω in order to narrow the energetic spectrum. A full characterization of the beam has been achieved by measuring the position, the size with Cerenkov detectors, the energetic spectrum and the transverse emittance at different points of the transmission line. Calculations has been done by using envelope and particle codes to perform the propagation of the beam. Good agreement has been achieved. Typically, 1 kA at 1.5 MeV is obtained.
