DATA-ACQUISITION AND PROCESSING SYSTEM FOR MOSSBAUER-SPECTROSCOPY

A state of the art data-acquisition system for four simultaneous and independent Mössbauer experiments has been implemented utilizing a general purpose minicomputer and low cost microprocessors. In this system, the microprocessors are dedicated to real-time data collection from the experiments while the minicomputer is being utilized for controlling the microprocessors and processing the data. Extensive consideration was given in the design of the system to achieve the most advantageous balance between hardware and software, i.e. to maintain the ease of handling and full capability of hardwired systems without employing sophisticated hardware. The concept of the design is independent of the type of processor, and may be applied to other experiments requiring real-time data collection and off-line data processing facilities. © 1979.
