THE ACCELERATION TEST OF THE APF-IH LINAC

An IH linac with Alternating Phase Focusing scheme has been fabricated to study a high efficiency cavity for a medical accelerator injector. This linac was designed to accelerate C4+ ions from 39 keV/u up to 1.9MeV/u. In order to test this linac, a test stand was just assembled which consists of a P.I.G. ion source, bending magnets and focus lenses. The total length of the test stand is less than 5 m including 1.5 m of linac tank length. The operation frequency of the cavity is 97.6MHz. We will report linac design, fabrication and the test bench.
