Development of Data Processing Software for NBI Spectroscopic Analysis System

A set of data processing software is presented in this paper for processing NBI spectroscopic data.For better and more scientific managment and querying these data,they are managed uniformly by the NBI data server.The data processing software offers the functions of uploading beam spectral original and analytic data to the data server manually and automatically,querying and downloading all the NBI data,as well as dealing with local LZO data.The set software is composed of a server program and a client program.The server software is programmed in C/C++under a CentOS development environment.The client software is developed under a VC6.0 platform,which offers convenient operational human interfaces.The network communications between the server and the client are based on TCP.With the help of this set software,the NBI spectroscopic analysis system realizes the unattended automatic operation,and the clear interface also makes it much more convenient to offer beam intensity distribution data and beam power data to operators for operation decision-making.     

The Timing System of the Neutral Beam Injector on EAST

In order to synchronize the elements of the EAST Neutral Beam Injector(NBI)spatially located in several places,a distributed Timing System(TS) is developed in this paper.The timing system provides a clock reference for synchronization and an interlock protection of the EAST NBI system.It sends timing signals to field devices,controls the pulse widths of the timing sequences,and provides a sampling clock for the Data Acquisition System(DAS).The timing system also generates analog waveforms to control power supplies and gas supplies according to the operator’s configuration.The timing system is developed on a PXI(PCI extensions for Instrumentation) platform consisting of a Lab VIEW workstation and a timing control terminal.The timing control terminal consists of a timing node and several control interface crates.Two timing nodes are configured in one beam line.Each node is responsible for the timing sequence,analog generation and feedback control for one ion source.The architecture and implementation of the timing system are presented in this paper.     

河南省侏罗纪盆地初探

依据对河南省侏罗纪盆地特征分析，初步认为在早中侏罗世由于断裂活动形成了继承性济源盆地、新生性义马盆地；在中晚侏罗世由于断裂活动形成了沈丘断陷盆地、罗山－潢川山前坳陷、马市坪－留山山间盆地；并指出前三个盆地为油气勘探较有利地区。     

The Implementation of Computer Data Processing Software for EAST NBI

One of the most important project missions of neutral beam injectors is the implementation of 100 s neutral beam injection （NBI） with high power energy t.o the plasma of the EAST superconducting tokamak. Correspondingly, it＇s necessary to construct a high-speed and reliable computer data processing system for processing experimental data, such as data acquisition, data compression and storage, data decompression and query, as well as data analysis. The implementation of computer data processing application software （CDPS） for EAST NBI is presented in this paper in terms of its functional structure and system realization. The set of software is programmed in C language and runs on Linux operating system based on TCP network protocol and multi-threading technology. The hardware mainly includes industrial control computer （IPC）, data server, PXI DAQ cards and so on. Now this software has been applied to EAST NBI system, and experimental results show that the CDPS can serve EAST NBI very well.
