摘要：
A compact accelerator-driven neutron source (CANS) has been proposed and designed by the Peking University (PKU) RFQ group. The source is based on a compact deuteron RF accelerator that delivers an average current of a few mA of deuterons at 11 MeV to the target. The accelerator consists of a short radio frequency quadrupole (RFQ) followed by efficient interdigital H-mode drift tube linac (IH-DTL) structure. The total length of the whole accelerator structure is 4.96 m, including 1.76 m for the 4-vane RFQ and 2.70 m for the IH-DTL. The dynamic simulation results show that the beam has excellent quality, with transmission efficiency higher than 99%. The transverse and longitudinal normalized rms emittance at the DTL exit is 0.29 mm.mrad and 0.12 MeV.deg, respectively. Details of the beam dynamics of the RFQ and IH-DTL are presented in this paper.
