Nuclear Physics Research Committee (NPRC)
In 1961 the Nuclear Physics Research Committee (NPRC) was aimed to define and arrange the experimental nuclear physics research programme of CERN on the Proton Synchrotron (PS) and the Synchro-Cyclotron (SC) machines.
The NPRC was formed from representatives of three committees :
• Electronic Experiment Committee (EEC) : Commonly called the Physics I Committee, considered and chose proposals for experiments using electronic counters and spark chambers.
• Track Chamber Committee (TCC) : Commonly called the Physics II Committee, considered and selected proposals for experiments using the bubble chambers at CERN : the 2 m hydrogen chamber (HBC-200), the 81 cm hydrogen chamber (HBC-81) and the heavy liquid chamber (HLBC).
• Emulsion Experiments Committee (EmC) : Commonly called the Physics III Committee, which groups the former Emulsion Experiments Committee and Nuclear Structure Committee considered and selected proposals for experiments using nuclear emulsions and experiments into nuclear structure.
The members of the NPRC were the chairmen of the three committees mentioned above, and representative of the CERN Departments concerned, Physics I, Physics II, Theoretical studies (TH) and the Proton Synchrotron Department (PS). The NPRC meetings were also attended by the PS co-ordinator and, when his presence was needed, by the SC co-ordinator.
Once the NPRC had approved an experiment or a test aimed at establishing the feasibility of an experiment, the team (generally consisting of physicists from National laboratories, European universities and CERN, working in collaboration), could begin the preparatory work in conjunction with the PS staff responsible for beam lay-outs and other technical facilities. In addition to approving new proposals, the physics committee and the NPRC regularly reviewed the status and needs of the various experiments in progress. At all stages, the committees sought to further the collaboration between CERN and physicists throughout Europe.
During the first meeting of the NPRC on the 21 November 1960, Victor Weiksskopf, the chairman, proposed that two kinds of meeting be held. One to take place bi-annually, was to assemble a very large number of people ; its purpose was to elaborate a research policy for CERN. The other, smaller type would meet every two or three months, and would concern itself with the immediate programme.
These ideas were widely debated between November 1960 and February 1961. John Adams, the CERN Director-General, took up a third position, he proposed that the four committees be kept and that they meet each month. On 6 February the Directorate rallied to his opinion and settled the final composition of the NPRC. It was to comprise the four scientific members of the Directorate (Adams, Hine, Van Hove, Weisskopf), the chairmen of the three specialist committees (Gregory, Powell and Salvini) and seven CERN Senior Staff, essentially the divisional leaders. The NPRC met for the first time on 8 and 9 March 1961.
The last meeting of the NPRC was held on the 3 December 1975. The NPRC became the Research Board, whose first meeting was held on 15 December 1975.
