Abstract
In the framework of the DARIA project (neutron source Dedicated to Applied Research and Industrial Applications) the 13 MeV, 162.5 MHz and 100 mA pulse proton linac is under development at the National Research Centre “Kurchatov Institute” – Kurchatov Complex for Theoretical and Experimental Physics. The linac includes RFQ (Radio Frequency Quadrupole) and DTL (Drift Tube Linac) sections. This article is devoted to the development of the DTL. The type of accelerating structure for creating high-frequency fields, which consists of a chain of multi-gap resonators, was determined. The optimal number of gaps in the resonators was selected. The choice of the main parameters and the analysis of various structures of the focusing periods were carried out. The results of the beam dynamics simulation in DTL are presented. The influence of Coulomb forces on particle dynamics in DTL was studied. The growth of the emittance in the DTL section was analyzed. The capabilities of the section for a wide range of input current and input beam emittance were considered.
