Machine à tisser les fils pour chambres proportionnelles multifilaires

Machine for weaving wires for use in multiwire proportional wire chambers: An older version of the machine pictured was used to to wind the (thick) wires used for spark chambers. In 1968, Georges Charpak invented the Multiwire Proportional Chamber, and the machines were modified to handle the thinner (20 µm) wires used in these machines. Charpak won the 1992 Nobel Prize in Physics "for his invention and development of particle detectors, in particular the multiwire proportional chamber".
