In nuclear fusion experiments in large helical device (LHD), a lot of videos containing the images of plasma discharge are recorded. An observation of the recorded images of plasma light emission can lead to a new discovery or help to optimize the op

This paper proposes a parallel indexing scheme of a large amount of data in order to resolve the issues about time limitation. Three kinds of computing-nodes are introduced. These are reception-nodes, representative-nodes, and normal-nodes. A recepti

Publikováno v: IIAI-AAI

This paper tries to clarify the causes of unusual plasma emission. Unusual plasma emission is required to be predicted because a bright flash often observed inside of the machine may cause a failure of a superconducting plasma confinement device. The

The Large Helical Device (LHD) successfully started the deuterium experiment in March 2017, in which further plasma performance improvement is envisaged to provide a firm basis for the helical reactor design. Some major upgrades of facilities have be
