This technique guarantees a single resonant frequency for the system insuring rapid turn on. The accelerator field amplitudes and phases are locked together without any critical tuning of individual components. This approach also makes the system inherently an ideal rf power combiner and allows operation even if an rf unit is off line. Benefits: This technique relaxes tolerances for accelerator cavity fabrication and simplifies control system requirements thereby reducing the cost of fabricating accelerator systems for applications requiring high beam current and beam power. It also increase the reliability and availability of the beam thereby reducing operational and ,maintenance costs. Return
