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.
This paper reviews the innovations which have recently been made on the isochronous cyclotron. These include: spatial and time beam diagnostic system, a NMR system for magnetic field stabilizing in 2-20 kG range, the system of automatic tuning control of the cyclotron resonator frequency in the 6-20 MHz range, putting into operation of a compact research cyclotron specially designed and built for detailed central region orbit dynamics investigation.
