Track Chamber Committee
In 1960 the Director-General John Adams proposed a number of measures to define a global policy for the exploitation of the new Proton Synchrotron. He decided to create three committees, one for each experimental technique used:
- Bubble Chambers : Track Chamber Committee (TCC)
- Emulsions : Emulsion Committee (EmC)
- Electronic : Electronic Experiments Commitee (EEC)
These three new committees were proposed to replace the Advisory Committee and Bubble Chamber Committee.
The TCC functions were to propose to the Nuclear Physics Research Committee track chamber experiments to be carried out at CERN, and also to form a link between the European track chamber groups and the CERN Laboratory.
The TCC came into operation in 1961, and met about once a month. It comprised a Chairperson (a senior physicist working on track chamber experiments, not on the staff of CERN) and members (representatives of CERN and other European track chamber groups (including picture evaluation groups)) wanting to use CERN facilities.
After 1966 the TCC was commonly known as the Physics II (PH-II-COM). It considered and selected the proposals for experiments using the bubble chambers at CERN :
- 2 m Hydrogen Bubble Chamber (HBC200)
- the 81 cm Hydrogen Bubble Chamber (HBC81)
- the Heavy Liquid Bubble Chamber (HLBC)
In 1976 (end of the bubble chambers period) John Adams and Leon Van Hove rationalized the system, abolishing the committee system based on experimental technique, and basing it instead on the machine. EEC and TCC merged to become the Proton Synchrotron Committee (PSC).
