An interdigital H-mode structure drift tube linac (IH-DTL) with alternating phase focusing (APF) has been developed downstream of a 4-vane type RFQ linac at te National Institute of Radiological Sciences as a compact injector for a heavy-ion medical synchrotron. Te rf frequency of both linacs is 200 MHz, and te total length of te two linacs is less than 6 m. They can accelerate heavy ions having a charge to mass ratio of 1/3 up to 4 MeV/u. Te accelerated current of 12C4+ is as high as 380 electric uA, and beam transmission through te APF IH-DTL is better than 96%. This compact injector-linac scheme might give a possible solution for a compact cancer therapy facility with heavy-ion beams.
