Test of a radio-frequency quadrupole cold model

In the framework of TRASCO Project (the Italian feasibility study for a waste transmutation linac) we have built and tested an aluminium model of a segmented resonantly coupled Radio-Frequency Quadrupole (RFQ), in order to determine the parameters of a 5 MeV and 30 mA proton beam RFQ. Bead perturbation measurements are performed, and the field stabilization respect to small perturbations of quadrupole fundamental mode is studied. A comparison between experimental results and a theoretical model is also reported.
