                         simulation, this work demonstrates that transittime tubes with 
                         stepped RF electric-field profiles can provide electron conversion 
                         efficiency in excess of 40 percent. This represents a two-fold 
                         enhancement in the conversion efficiency in comparison with that 
                         obtained with a longitudinally uniform electric-field 
                         distribution. Such an improvement arises from a phase 
                         synchronization process due to the action of RF electric fields of 
                         reversed signs along the interaction space. © 2014 IEEE.",
