The Mechanical Design for the Darht-II Downstream Beam Transport Line
摘要：
介绍了DARHT II装置第二轴下游束流传输线的机械设计。DARHT-II项目是LANL，LBNL和LLNL之间的合作。DARHT II是一个20兆电子伏、2000安培、2毫秒的线性感应加速器，设计用于产生短脉冲X射线，用于对致密物体进行射线照相。下游束流传输线是从加速器末端到韧致辐射靶的约20米长的区域。在这条拟议的传输线内，有15个传统的螺线管、四极和偶极磁铁;以及几个特殊磁铁，用于将束流传输并聚焦到目标和束流倾倒场。有两个高功率束流收集器，其设计为在加速器启动和操作期间吸收80 kJ/脉冲。这些元素的机械设计方面。
英文摘要：
This paper describes the mechanical design of the downstream beam transport line for the second axis of the Dual Axis Radiographic Hydrodynamic Test (DARHT II) Facility. The DARHT-II project is a collaboration between LANL, LBNL and LLNL. DARHT II is a 20-MeV, 2000-Amperes, 2-msec linear induction accelerator designed to generate short bursts of x-rays for the purpose of radiographing dense objects. The down-stream beam transport line is approximately 20-meter long region extending from the end of the accelerator to the bremsstrahlung target. Within this proposed transport line there are 15 conventional solenoid, quadrupole and dipole magnets; as well as several speciality magnets, which transport and focus the beam to the target and to the beam dumps. There are two high power beam dumps, which are designed to absorb 80-kJ per pulse during accelerator start-up and operation. Aspects of the mechanical design of these elements are presented.
