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

Numerical modeling of electron-optical scheme of electrostatic decapole-cylindrical mirror energy analyzer has been carried out.Trajectory analysis of the charged particles motion in decapole-cylindrical field has been conducted.Two regimes of second-order angular focusing ("ring-ring" and "axis-ring" types) were found.Focusing properties of decapolecylindrical analyzer in second-order angular focusing regime for different types of focusing were calculated.Instrument functions were obtained; energy resolution and luminosity of device were estimated.
