摘　　要：国际热核实验堆(International Thermonuclear Experimental Reactor,ITER)是世界上最大的超导托卡马克装置,其中央控制系统CODAC(Control,Data Access and Communication)为ITER装置及其各个子系统提供了丰富的控制系统设计与开发工具。ITER极向场整流器系统作为其子系统之一在运行的过程中会产生大量的实验数据,大量数据的高速采集给数据的存储造成很大的困难,其控制系统需要及时地将采集到的数据进行有效的存储,并提供相应数据的查看方式。本文采用CODAC提供的数据归档系统对极向场控制系统数据进行有效的管理。在充分了解该数据归档系统的基础上,对该数据归档系统的使用和可用性进行了详细的介绍。Background： International Thermonuclear Experimental Reactor （ITER） is the largest superconducting Tokamak device in the world. CODAC （Control, Data Access and Communication） system has been adopted as the central control system for ITER device. This system provides ITER subsystems with many tools to design and develop its own sub-control system. ITER device will produce a larger number of experimental data during its operation. Fast data acquisition and large volume of data can bring great difficulty to control system. Purpose： This study aims to design and implement a data archiving system for Poloidal Field （PF） control to archive these data effectively in time, and provide some way to check the data. Methods： Data Archiving Network （DAN） of CODAC is employed to implement an effective data archiving system for ITER PF control system, and a program to do data lookup is designed using Python. Necessary experiments to simulate the PF system were performed to test this data archiving system flexibly. Results and Conclusion： Experimental results show that this data archiving system can store experimental data effectively.s
