The IBM 7090 was installed at CERN in 1963. It was about four times more powerful than the 709. The computer was connected to a device call a Hough-Powell digitizer (HPD) – a machine that scanned films from bubble chambers, measured important tracks, and sent the information directly to the 7090. A second device, "Luciole", was also connected to the computer, providing fully automatic measurements from spark-bubble chambers. Over 300,000 frames of spark-chamber film were automatically scanned and measured in this way, beginning the trend towards online use of computers for processing experimental data.
