Data confidence 85 high
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

Abstract A prism mass spectrometer with triple focusing of the ion beam using a cone-shaped achromatic prism (CSAP) is considered. The CSAP has a record high angular mass dispersion of approximately 50 rad upon 100% variation of the mass. The performance of a prism mass analyzer with collimating and focusing transaxial lenses is simulated using the Monte Carlo method. The resolution and the quality parameters of such a mass analyzer are shown to exceed those of existing static devices by several times. A resolving power of several million can be obtained using narrow beams on a small device with sub-meter dimensions.
