Nowadays (2015) such seals are used with Klein Flanges. 1970 http://cds.cern.ch/record/764501 http://cds.cern.ch/record/764501 Album with images scanned from original photo negatives Machine for weaving wires for use in multiwire proportional wire chambers Industry and Technology 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". 1970 http://cds.cern.ch/record/764514 http://cds.cern.ch/record/764514 Album with images scanned from original photo negatives BEBC power entry Industry and Technology The power entry for the Big European Bubble Chamber (BEBC) was inserted in a tube. The engraved chicanes (grooves) thus allowed circulation of the cooling fluid, in this case helium. L'entrée de courant du BEBC était sertie dans un tube. Les chicanes usinées permettaient ainsi la circulation du liquide de refroidissement (Hélium). 1970 http://cds.cern.ch/record/764517 http://cds.cern.ch/record/764517 Album with images scanned from original photo negatives CERN PhotoLab No caption CERN-PHOTO-7001354 Damaged commutator from a DC motor 1970 http://cds.cern.ch/record/1765891 http://cds.cern.ch/record/1765891 Image scanned from original photo negative on 07 Oct 2014 CERN PhotoLab No caption CERN-PHOTO-7305030 1973 http://cds.cern.ch/record/1761789 http://cds.cern.ch/record/1761789 Image scanned from original photo negative on 26 Sep 2014 CERN PhotoLab No caption CERN-PHOTO-6908152 Multi-wire proportional chamber (MWPC) 1969 http://cds.cern.ch/record/1764794 http://cds.cern.ch/record/1764794 Image scanned from original photo negative on 04 Oct 2014 CERN PhotoLab CERN-PHOTO-6909143_a Model of an ISR split field magnet, made up of two compensating magnets and installed at point 4 of the Intersecting Storage Rings.
