A visualization environment for an on-line monitoring and control system for an experiment to search for T-violation in K{sup}+ decay

摘要

The main goal of experiment E246 at the KEK (National Laboratory for High-Energy Physics, Japan) 12-GeV proton synchrotron is the search for the T-odd muon polarization in the decay K{sup}(+)→π{sup}0μ{sup}(+)v(K{sub}(μ3). To satisfy the experimental requirements, a graphic user-oriented on-line system for data monitoring and graphic representation of the most significant experimental parameters in the form of histograms, indicators, and 2D-displays has been developed. This paper describes the E246 data acquisition system, on-line system environment, obtained monitoring capabilities, set of graphic user displays, and the GUI (Graphical User Interface), development methodology for the HEP (High-Energy Physics) on-line visualization.
