Emulsion Experiment Committee

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 create three Committees, one for each experimental technique used:

• Emulsions: Emulsion Committee (EmC)
• Electronic: Electronic Experiments Commitee (EEC)
• Bubble chambers: Track Chamber Committee (TCC)

These three new committees were proposed to replace the Advisory Committee and Bubble Chamber Committee.

The EmC's 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.

The EmC came into operation in 1961, and met about once a month. It comprised a Chairperson (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 emulsion techniques decreased rapidly, and following a proposal by Bernard Gregory, Gösta Ekspong and Léon Van Hove, it was decided to merge the EmC with the Nuclear Structure Committee (NSC) to form the Physics III-Committee (PH-III-COM).

In 1976 (end of the bubble chambers period) John Adams and Léon Van Hove rationalized the system, abolishing the committee system based on experimental technique, and basing it instead on the machine. PH-III Committee became the SC Committee (SCC), which existed until 1978.
