EAST超导托卡马克是我国开展受控核聚变研究的新一代实验装置,离子回旋波加热(ICRH)是在该装置中加热等离子体的重要手段之一。离子回旋加热系统中的发射机和天线两者各有一个地电平,两个地电平会存在严重的相互干扰。高功率同轴隔直器的作用是用来隔断两者之间的直流通路,从而把两端的地电平分开,保证发射机和天线系统的正常运行。论文介绍了隔直器的原理、工程结构和设计指标,分析了S参数、端口驻波比的计算和仿真,最后给出了实际的隔直器参数曲线。 相似文献

Neutral beam injection (NBI) heating is one of the most efficient auxiliary plasma heating methods for fusion devices. The data acquisition control system (DACS) with PXI (pe- ripheral component interconnect extensions for instrumentation) data acquisition card for the first NBI system in the experimental advanced superconducting tokamak (EAST) is presented in this paper. As an important sub-system, DACS is designed to obtain physical measurement signals in the EAST NBI system and to deal and store these data with the Lempel-Ziv-Oberhumer (LZO) lossless data compression algorithm, as well as offer convenient data call-back and access inter- faces to the user for examining and analyzing the data. Experimental results show that accurate data will ensure that researchers correctly analyze it and then properly adjust the experimental parameters or operation, so DACS should take a large step in improving experimental efficiency. Tile hardware and software sections are briefly presented in this paper, and now this system has been tested to be able to work reliably and steadily. 相似文献

This paper introduced recent development of data acquisition system(DAS) on the HL-2A tokamak. The existing DAS has to be remodeled because of the evident improvement on HL-2A itself and the increasing amount of corresponding experimental data. First, the experimental network on HL-2A Tokamak as a communication center is described in detail. Secondly, "The File's Format & Criterion of Experimental Data on HL-2A Tokamak" as the core of the new software is also presented. Thirdly, not only a multi-screen image display system on HL-2A is discussed, but also the build-up of a new display wall system is dealt with. Finally, on the graphical WINDOWS platform and on the basis of the new Data File's Format & Criterion, the new software on HL-2A is described, including a new multi-layer database management program, a real-time processing program, a common interactive analytic processing program and a data post-processing program, which is now under development. 相似文献

A new possible data archive format for storing huge amounts of data for EAST control anddata acquisition system is presented. This new general-purpose data archive format is network-transparent, i.e, machine-independent and has been implemented in terms of XDR (eXternal Data Representation). We test this format by using EFIT (Equilibrium Fitting) code on different operation systems, namely Linux and Windows, different processors, namely Sun and Pc, and different programs, namely in Fortran and C language. It can be easily used by different computers and different programming languages. 相似文献

HT-7 is the first superconducting tokamak device for fusion research in China. Many experiments have been done in the machine since 1994, and lots of satisfactory results have been achieved in the fusion research field on HT-7 tokamak^[1]. With the development of fusion research, remote control of experiment becomes more and more important to improve experimental efficiency and expand research results. This paper will describe a RCS (Remote Control System),the combined model of Browser/Server and Client/Server, based on Internet of HT-7 distributed data acquisition system (HT7DAS). By means of RCS, authorized users all over the world can control and configure HT7DAS remotely. The RCS is designed to improve the flexibility, opening, reliability and efficiency of HT7DAS. In the paper, the whole process of design along with implementation of the system and some key items are discussed in detail. The System has been successfully operated during HT-7 experiment in 2002 campaign period. 相似文献
