Data acquisition and processing system for a mass-spectrometer's site

A two-level measuring-calculating system (MCS) has been developed; BESM-6 computer is used as a central computer at the upper level, at the lower - a terminal computer of the RPT type (Videoton, Hungary). MCS is designed for: the experimental data acquisition in the RPT immediate memory from several (up to five) mass spectrometers; communication of data accumulated in BESM-6 through a communication link; mathematical processing by BESM-6 and obtaining results at the mass spectrometer region. Simultaneous and independent recording of data from a mass spectrometer group as well as communication of data accumulated in BESM-6 without disturbance of RPT operating mode are provided with specially developed programs executed in RPT under OC RPS control. BESM-6 software is based on basic possibilities of OC RPS with respect to work with terminals. Received data is entered the archive in the form of variable length files by means of direct access programs; such archive organization permits to use the data for subsequent analysis and processing with the help of programs using any level languages
