Abstract
Abstract Flexible and fast deployable data acquisition system has always been demanded by tokamak facilities. This work proposes a full stack data acquisition, archive and access solution for J-TEXT based on Web technologies. This solution is based on a single unified control system framework, and all of the above systems are using the same communication interface: HTTP RESTful API that unifies the status monitoring, command sending even diagnostic data accessing and so on, which is called the unified data access. A working system on J-TEXT is built using this full stack solution. It consists of a data acquisition system for ECEI, an archiving system built on HDF5 files, a data management system and a set of unified data access interface to access the experiment data. This working system is integrated into J-TEXT CODAC system which is based on EPICS CA and MDSplus. Flexible and modular design makes it easy to apply this solution to different systems, even using only a part of it. Some diagnostic systems other than ECEI also use this solution to upload their data to the MDSplus database just with different configurations. Users can access data without noticing which data source is providing to them. All the user interface in this system are built as web pages which can be accessed using web browser on various devices.
