Online control package for COSY-TOF experiment — •Ekaterina Borodina1,2, Eduard Roderburg1, and James Ritman1 — 1Institute fuer Kernphysik I, Forschungszentrum Juelich GmbH, 52325, Juelich, Germany — 2Moscow State Institute of Electronics and Mathematics, Russia
The new Straw Tube Tracker and Quirl Microstrip detectors have been installed at the TOF (Time Of Flight) experiment at the COSY accelerator in IKP 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 for control the proper functionality of all channels is being developed.
The online controlling based on visualization of key parameters of detectors plays an important role. The concept and the techniques of the online software package are developed for the COSY-TOF experiment. It consists of conversion software, which transforms a binary data stream from the DAQ to detector oriented event format, methods of IPC (Inter-Process Communications), and GUI (graphical user interface). To achieve data transfer through the network and real time data performance the IPC tools - sockets and shared memory are used. A special GUI, TOF-ONLINE has been developed, based on ROOT. The GUI allows the detectors, plotting spectra, resetting data, etc., to be selected in an intuitive way. Examples of the visualization and the results of the first beam time will be introduced. Supported in part by FZ-Juelich.
