Research progress on high intensity hadron accelerator in China

High intensity hadron beam has wide-range important applications.In recent years,several projects with intense-beam hadron accelerator are under design,development or construction in China.We are facing a lot of challenges in beam physics and key technology of the accelerators.Beam loss and beam emittance must be minimized for such a high intensity accelerator.Space charge effect and nonlinear dynamics should be taken into account in beam physics and accelerator design.In this paper we will present the recent research progress in China on beam dynamics,new technology development and beam experiments for intense beam hadron accelerators,including linear accelerator,synchrotron and cyclotron.
