The TOF (Time Of Flight) experiment at the COSY accelerator in the FZ-Juelich has successfully performed a first measurement for the studies of the hyperon-nucleon interaction with a polarized beam at 2.95 GeV/c beam momentum. For these measurements a silicon quirl telescope and a straw tube tracker were recently installed in order to improve the mass reconstruction and increase the reconstruction efficiency. The increased complexity of the detector system required a user friendly software for diagnostics and visualize the proper functionality of detector components.
This software includes data conversion, checking and visualisation routines, full detector geometry and GUI (graphical user interface). For visualisation of single events the event display, based on ROOT geometry classes, was developed. User friendly GUI provides convenient online monitoring of data, being acquired during the experiment, and selection of the event display parameters. The different parts of software are independent and run in parallel. For illustration, examples of data diagnostics and event display from the last experiment will be presented.
Supported in part by FZ-Juelich.
