Design and implementation of J-TEXT tokamak remote participation system

An open platform for users to participate in J-TEXT tokamak experiment via Internet remotely was designed. The implementation of Web service applies the Representational State Transfer (RESTful) software architecture, developers can use the open API to develop tokamak applications based on their requirements. Authentication and Authorization system protects the open API against hacker attacks. Implementation of J-TEXT tokamak remote participation system based on ASP.NET Web API framework. In the real time data updating area it uses ASP.NET SignalR library to implement multiple server push strategies. The system is flexible and compatible with Experimental Physics and Industrial Control System (EPICS) software. Now it has been already integrated into the J-TEXT Control, Data Access and Communication (CODAC) system. The test and application results show that the system can work continuously and stably, and meet the requirements of tokamak remote participation. (authors)
