Abstract

The new proton linear accelerator (linac) with output energy 13 MeV and 100 mA current is under development at NRC “Kurchatov Institute” - ITEP for DARIA project. The linac consists of Radio-Frequency Quadrupole (RFQ) and Drift Tube Linac (DTL) with operating frequency 162.5 MHz. The RFQ is based on 4-vanes structure with shifted coupling windows. DTL has a modular structure and consists of separated individually phased cavities with focusing magnetic quadrupoles located between the cavities. The DTL is based on interdigital H-mode (IHDTL) 5-gaps cavities. The 6D beam matching between RFQ and DTL is provided by magnetic quadrupole lenses and RF-bunchers. The paper presents results of the radio-frequency (RF) design, thermal analyses and RF tuning of RFQ linac accelerating structure.

DARIA项目射频四极线性加速器的参数

NRC“库尔恰托夫研究所”-ITEP正在为DARIA项目开发输出能量为13 MeV、电流为100 mA的新型质子线性加速器。直线加速器由射频四极管（RFQ）和漂移管直线加速器（DTL）组成，工作频率为162.5MHz。RFQ基于带偏移耦合窗口的4叶片结构。DTL具有模块化结构，由分离的单独相控腔组成，聚焦磁四极位于腔之间。DTL是基于叉指H模（IHDTL）5间隙腔。RFQ和DTL之间的6D光束匹配由磁性四极透镜和RF聚束器提供。本文介绍了RFQ直线加速器加速结构的射频设计、热分析和射频调谐的结果。
