34. MINT, ITER Interactive Data Visualization Tool

Dr RODRIGO CASTRO (CIEMAT)

Information retrieval, dimensionality reduction and visualisation in fusion databases

Oral

MINT (Make Informative and Nice Trends) is an ITER graphical data visualization and exploration tool designed for plant engineers, operators, and physicists. Its requirements were gathered through interviews with various stakeholders, and its architecture was planned for a long-term project such as ITER. As such, a modular design and clear definition of generic interfaces (abstraction layer)...

16. Metadata framework for distributed real-time control systems

Information retrieval, dimensionality reduction and visualisation in fusion databases

Oral

Modern real-time plasma control systems will be modular and distributed. This provides several advantages: component isolation, component simplicity and robustness, scalability, and the possibility of utilizing heterogenous execution environments. In addition these systems are amenable to machine learned pipelines. However such systems incur the liabilities of system complexity and...

39. End-to-end intra-pulse data analysis at ITER: first steps from magnetics to live display

Information retrieval, dimensionality reduction and visualisation in fusion databases

Oral

Interpreting diagnostic data as early as possible after a plasma pulse is an important capability of modern tokamaks [1, 2, 3]. This is particularly critical for ITER, since a quick feedback on the plasma performance (shape, confinement, power balance, impurities, ELMs, …) during the pulse is increases efficiency of operation and furthers the implementation of the scientific program that...

7. The role of structured multi-purpose databases in fusion research

Dr Henri Weisen (Karazin National University)

Information retrieval, dimensionality reduction and visualisation in fusion databases

Oral

Most databases in fusion research are devoted to a single topic, such as energy confinement, H-modes, profiles or disruptions. In order to allow for a wide range of analysis, modelling and validation tasks, a broad-based multi-purpose database, JETPEAK, has been developed for JET. This database currently includes 23000 stationary state (∂/∂t≈0) manually selected samples, averaged time windows...

32. Design Concept of Intelligent Integrated Control System for Neutral Beam Injection

Information retrieval, dimensionality reduction and visualisation in fusion databases

Oral

Due to the specificity of Neutral Beam Injection (NBI) system, the control of its actual physical system is achieved through the Integrated Control System (ICS). The NBI ICS is used to coordinate the operation of various subsystems of NBI while ensuring steady-state operation of entire system and the safety of experimenters. The early NBI ICS in our lab was designed based on a centralized...
