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

Abstract We present the design and implementation of a compact digital data acquisition system based on the STM32F407 microcontroller for use in charged-particle spectroscopy. The system digitizes signals from a two-detector telescope (Δ E-E ) and transfers the results to a PC in real time via USB. The approach combines an analog front-end (preamplifier, CR-RC shaper, comparator, and peak detector) with microcontroller-based digitization and data transfer. This setup allows construction of two-dimensional coincidence matrices (Δ E vs. E ) for particle identification.
