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 dynamic characteristics of the discharge current in a thermonuclear plasma focus installation and its dependence on neutron emission was studied. The dynamics of the formation of discharge pickcurrent was measured and analysed through the Rogowskiy belt and activated neutron flux with an activated silver foil detector. According to the results of the analysis, the discharge peak current at a voltage of 18 kV from 200 to 265 kA and the pinch current was varied depending on the pressure between 178–230 kA. Accordingly, the neutron flux was 8·106–2.2·107 neutron/imp. The dependence of neutron emission on discharge pinch current in plasma focus device installation is described.
