“…Then MCS connects with sub-systems to send the configuration. After the experiment starts, the MCS collects data from each sub-system at the field control level [5] . Taking security into consideration, the MCS needs to be isolated from external data in case the data saved is modified illegally.…”

Neutral Beam Injection (NBI) is one of the most effective means for plasma heating. Experimental Data Publishing Software (EDPS) is developed to publish experimental data to get the NBI system under remote monitoring. In this paper, the architecture and implementation of EDPS including the design of the communication module and web page display module are presented. EDPS is developed based on the Browser/Server (B/S) model, and works under the Linux operating system. Using the data source and communication mechanism of the NBI Control System (NBICS), EDPS publishes experimental data on the Internet.

“…1, NBI data server, DAQ device, experimental record terminal and data query terminal are the main parts of CDPS. For the security of communication between different devices on the NBI local network, network registration service is offered by the NBI control server [4] . The data server and DAQ device will be registered to the NBI control server at the moment their applications start, thus they can be treated as legal clients of the NBI control server to get neces-sary services during experiments if authentication succeeds [5] .…”

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 to 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.
