Résumé :

The Inter-University Institute for High Energies in Brussels is involved in experiments based on the analysis of film from several track chambers: the "big" and "little" European Bubble Chambers (BEBC and LEBC) and the UA5 streamer chamber. In order to scan and measure these difficult pictures in optimal conditions, a rather versatile device which we originally called "BEBC table" was designed in the laboratory, offering a high-precision track-ball driven X-Y stage, optical projection with dual magnification, and various operator controls. A PDP-11/40 running RSX-11 M provides real-time support for five of these devices. A link between the PDP-11 and a DEC system 10 allows the geometrical reconstruction of the events to be performed on-line, with feedback to the BEBC table operator. © 1982.
