Administrative history

In 1960 the Director-General John Adams proposed a number of measures to define a global policy for the exploitation of the Synchro-Cyclotron and the new Proton Synchrotron. He decided to reorganise the system by creating three Committees, one for each experimental technique used :

  • Emulsions : Emulsion Committee (EmC)
  • Electronic : Electronic Experiments Commitee (EEC)
  • Bubble chambers : Tracks Chambers Committee (TCC)

These three new committees were proposed to replace the SC Advisory Committee, PS Advisory Committee, Emulsion Advisory Committee and Bubble Chamber Committee. The EmC functions were to propose to the Nuclear Physics Research Committee emulsion experiments to be carried out at CERN, and also to form a link between the European emulsion groups and the CERN Laboratory. EmC came into operation in 1961 and met about once a month. At the first meeting it was decided that the committee should comprise a chairman who shoud be a senior physicist working on emulsion experiments, not on the staff of CERN, and members, representatives of CERN and other European emulsion groups wanting to use CERN facilities.

In 1966 the importance of the emulsion technique was decreasing rapidly, and following a proposal by Gregory, Ekspong and van Hove, it was decided to merge EmC with the Nuclear Structure Committee (NSC). It was renamed Physics III-Committee (PHIII-COM).
