Abstract

The KSTAR cryostat is a 8.8 m diameter vacuum vessel that provides the necessary thermal barrier between the ambient temperature test cell and the supercritical helium cooled superconducting magnet providing the base pressure of 1/spl times/10/sup -5/ torr. The cryostat is a single walled vessel consisting of central cylindrical section and two end closures, a flat base structure with external reinforcements and a dome-shaped lid structure. The base structure has 8 equally spaced support legs anchored on the concrete base. The cryostat vessel design was executed to satisfy the performance and operation requirements. The mechanical penetration components with bellows were designed to restrict the displacements of all kinds of ports due to EM loads and thermal loads within the allowable limits. The major loads considered in this paper for the design of cryostat vessel are the vacuum pressure, the dead weight of vacuum vessel, PFC, and magnet which are total about 400 tons, the electromagnetic load driven by plasma disruption, and seismic loads. Based on these loads, structural analyses were performed. It was found that the maximum stress intensity was below the allowable limit, and that the cryostat vessel had buckling safety of over 5. Based on the results, structural robustness of the cryostat vessel has been proved.

KSTAR低温恒温器的结构设计与分析

KSTAR低温恒温器是一个直径8.8米的真空容器，在室温测试单元和超临界氦冷却超导磁体之间提供必要的热障，提供1/spl倍/10/sup -5/ torr的基压。低温恒温器是一种单壁容器，由中央圆柱形部分和两端封闭组成，具有外部增强的扁平基座结构和圆顶状盖子结构。基础结构有8个等间距的支撑腿锚定在混凝土基础上。为了满足性能和运行要求，进行了低温恒温器的设计。带波纹管的机械穿透部件的设计是为了将电磁载荷和热载荷引起的各种端口的位移限制在允许的范围内。本文设计低温恒温容器时考虑的载荷主要有真空压力、真空容器自重、PFC、磁体等共计约400吨的载荷、等离子体破坏驱动的电磁载荷和地震载荷。基于这些荷载，进行了结构分析。结果表明，低温恒温容器的最大应力强度在允许范围内，其屈曲安全性大于5。在此基础上，验证了低温恒温容器的结构稳健性。

期刊介绍： 19th-Century Music covers all aspects of Western art music between the mid-eighteenth and mid-twentieth centuries. We welcome--in no particular order--considerations of composers and compositions, styles, performance, historical watersheds, cultural formations, critical methods, musical institutions, ideas, and topics not named on this list. Our aim is to publish contributions to ongoing conversations at the leading edge of musical and multidisciplinary scholarship.
