Abstract

Abstract

A permanent magnet focused IH type drift tube linac (IH-DTL)cavity was designed for accelerating low energy proton. Using adaptive dimension adjustment, the beam phase at the center of every drift tube was adjusted to be equal to the set value. The IH-DTL designed in this paper has a length of 0.96 m and a shunt impedance of about 90 M/m, it can accelerate protons from 0.75 MeV to 2.5 MeV. The beam envelope in the IH-DTL was computed by the program TRACE3D. If the beam halo and errors were neglected, the beam loss can be controlled to be approximately 0.1% when the beam current is 50 mA.
