An 8-channel counter and histogramming sub-module: the basic building block for fast real-time data acquisition systems

Abstract

This paper presents an 8-channel counter and histogramming sub-module with local memory which in association with a dedicated motherboard and bus system forms a fully expandable data acquisition system. As a first application, the authors sued this sub-module to implement a 16-input Calibration Channel Unit module to carry out the acquisition of real-time calibration data (beam intensity, sample temperature...) for time-resolved Synchrotron Radiation experiments. This sub-module will also be used as the basis of the data acquisition system for the new fast wire per wire X-ray detector.
