Online control package and event display for the upgraded COSY-TOF experiment. — •Ekaterina Borodina1,2, Eduard Roderburg1, and James Ritman1 — 1Institut fuer Kernphysik I, Forschungszentrum Juelich GmbH, 52325, Juelich, Germany — 2Moscow State Institute of Electronics and Mathematics, Russia
The new Straw Tube Tracker and Silicon Quirl Telescope detectors have been recently installed at the TOF (Time Of Flight) experiment at the COSY accelerator in the FZ-Juelich. These new detectors increase the number of channels of the COSY-TOF detector by about a factor of 3. Therefore, a new control package to adjust electronic parameters and to diagnose the proper functionality of all components is being developed.
The COSY-TOF online controlling is based on visualization of single events and the analysis of statistical distributions of detectors data. It consists of conversion software, which transforms the binary data stream from the DAQ to a detector oriented event format; visualization routines, which create event display, spectra, etc. and stores them in shared memory files; methods of IPC (Inter-Process Communications) for real time performance; Geometry package and GUI (graphical user interface). The event display, based on ROOT geometry classes, represents graphically detector states and events in different ways of visualization during online sessions. Examples of the event display and results from the last experiment will be presented.
Supported in part by FZ-Juelich.
