Description

H-type structures are a dedicated candidate for cw operation because they can be cooled very efficiently. With the aid of additive manufacturing, in particular complicated and complex water-cooling channels inside stems and drive tubes can be realized. In a relatively small cw operated H-type buncher cavity with only a length of 540 mm and a diameter of 614 mm, rf power levels up to 24 kW were easily realized in long time performance.
