The resulting structure must be vacuum-tight to allow the passage of the particle beam and must ensure the electrical conduction necessary for generating the extremely high radiofrequency electric fields that accelerate the particles. It follows that the quality of the brazing that connects the cells is critical for the accelerator&#8217;s operation and requires very complex execution and control procedures.[\/vc_column_text][vc_empty_space][vc_single_image image=&#8221;4760&#8243;
