Big data (incl. smart data retrieval)

Presentation

Fusion devices such as ITER are expected to generate over one million sensor signals per discharge, each lasting 30 minutes or more. Identifying known patterns within these long time series is essential for understanding plasma behavior, but it poses significant computational challenges. In this work, we present a method for efficient pattern search in large-scale time series using FAISS, a...

Big data (incl. smart data retrieval)

Presentation

EAST tokamak, one of the most important Magnetic Confinement Fusion (MCF) devices in China, provides an important experimental platform for the study of steady-state advanced plasma operation. Over sixty diagnostic systems on EAST tokamak provides huge amounts of multimodal diagnostic data about MCF plasma. Diagnostic data of EAST tokamak has the characteristics of volume, variety and...
