PROJECT TITLE :

JRTF: A Flexible Software Framework for Real-Time Control in Magnetic Confinement Nuclear Fusion Experiments

ABSTRACT:

The magnetic confinement nuclear fusion experiments need varied real-time management applications like plasma control. ITER has designed the Fast Plant System Controller (FPSC) for this job. ITER provided hardware and software standards and tips for building a FPSC. In order to develop varied real-time FPSC applications efficiently, a versatile real-time software framework referred to as J-TEXT real-time framework (JRTF) is developed by J-TEXT tokamak team. JRTF allowed developers to implement completely different functions as freelance and reusable modules referred to as Application Blocks (AB). The AB developers solely want to concentrate on implementing the management tasks or the algorithms. The timing, scheduling, information sharing and eventing are handled by the JRTF pipelines. JRTF provides nice flexibility on developing ABs. Unit test against ABs will be developed simply and ABs will even be employed in non-JRTF applications. JRTF also provides interfaces allowing JRTF applications to be configured and monitored at runtime. JRTF is compatible with ITER customary FPSC hardware and ITER (Management, Knowledge Access and Communication) CODAC Core software. It will be configured and monitored using (Experimental Physics and Industrial Management System) EPICS. Moreover the JRTF can be ported to completely different platforms and be integrated with supervisory control software other than EPICS. The paper presents the look and implementation of JRTF as well as temporary check results.
