Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The paper presents the results of the first measurements of the heating temperature of the walls of the vacuum chamber on the KTM tokamak using non-contact methods during plasma discharges. The technical features and placement of the IR diagnostics used in the KTM tokamak are presented. The first experimental results of measuring the heating temperature of the graphite elements of the first wall of the KTM are demonstrated, which showed the operability of the diagnostics under KTM conditions.
