DESCRIPTION OF THE COLLECTION
This catalogue of papers and correspondence of Cecil Frank Powell is a supplement to those compiled in 1974 (catalaogue CSAC 12/6/74) and 1986 (catalogue CSAC 111/2/86), both available at the University of Bristol.
The collection is presented in a list of content. It covers the period ca. 1941 to 2002. Material supplementary to the previous catalogues has been found for Sections A (Biographical), B (Balloon and Aeroplane Flights), C (Publications), E (Correspondence) and F (Research). However Section G (Visits and conferences) is a completely new section.
Section A, Biographical, presents a series of six photographs of Powell's Cosmic Ray team including visiting scientists and students at the University of Bristol between 1949 and 1960. Those featured include Powell and his wife Isobel Powell, P. H. Fowler, J. H. Davies, D. H. Perkins and H. Heitler. It is numbered to follow on from catalogue CSAC 111/2/86 A.143.
Section B, Balloon and aeroplane flights is arranged in alphabetical order based on Powell's own folder titles and includes material on flight expeditions between 1953 and 1971. It is one of the larger sections of the catalogue and presents a good record of the research of Powell and his team (P. H. Fowler in particular). It includes correspondence, photographs, technical drawings, maps, memoranda and reports on aeroplane flights on Comet, Vulcan and VC10 aircraft between 1957 and 1964 and balloon flights in Bristol, Sardinia, Hyderabad (India), Scotland, Cardington (Bedfordshire), New Mexico, Victoria (Texas) and Sioux Falls (Minnesota) between 1953 and 1971. It also documents balloon making, collaboration with foreign universities and institutions, technical support with naval and air ministries, meteorological services in the United Kingdom and relations with NATO. It is numbered to follow on from catalogue CSAC 111/2/86 B.18.
Section C, Publications, includes documentation of four papers only. Most of the material relates to a paper entitled 'Therapeutic Applications of Beam of Negative Pion Mesons' on cancer treatment written by Powell and P.H. Fowler. It is numbered to follow on from catalogue CSAC 11/2/86 C.25.
Section E, Correspondence, forms the largest section of the collection. It was arranged in an alphabetical sequence as presented here and runs from A to S. The letters T-Z are to be found in catalaogue CSAC 111/2/86. The material covers a wide range of topics from collaboration on research and expeditions with national and foreign universities, to dealings with governmental bodies in the United Kingdom such as the Department of Scientific and Industrial Research or the United Kingdom Atomic Energy Authority and supra-national bodies abroad such as NATO. It also includes material on scientific societies and organisations such as the Royal Society and CERN, and national laboratories such as Rutherford, Culham Laboratories and the National Physical Laboratory. There is also material on the supply of cosmic ray research material by commercial companies, balloon flights expeditions and analysis of exposed emulsion stacks, the issues of atomic energy and nuclear weapons, exhibitions, publications of papers and proceedings of conferences. It is numbered to follow on from catalogue CSAC 111/2/86 E.76, though the sequence presented in this catalogue precedes it in the alphabet.
Section F, Research, is mainly related to collaboration on K- research with foreign universities and institutions. There is also material relating to n-p scattering and neutrino experiments. This material follows on from catalogue CSAC 12/6/74 75.
Section G, Visits and conferences, presents material from 1960 to 1965. Powell only attended some of the conferences but he filed and kept material relating to those he did not attend himself, some of which were attended by other members of his team. Conferences of particular significance to Powell were the series of Rochester conferences on High Energy Physics, the Ultra High Energy Nuclear Physics conference in Bristol (1963), various European Organisation for Nuclear Research (CERN) conferences and the 1965 International Union of Pure and Applied Physics conference.
Throughout this catalogue titles in inverted commas indicate the original typescript or manuscript titles of Powell's folders.
