La 51em session du Conseil du CERN

The Council met on 19 and 20 December 1973 under the Presidency of Professor W. Gentner. The Council Session opened , as usual, with progress reports from the Director Generals of Laboratory I and Laboratory II. Since the CERN Courier covered work on construction of the 400 GeV synchrotron , the SPS , at Laboratory II in the November and December issues, the CERN Courier gives here a report of Prof. W. Jentschke concerning the physics which has come form the experimental programme at the 28 GeV Proton Synchrotron and the Intersecting Storage Rings.
