The papers relate essentially to the design and development of the cavity magnetron 1939-45, though there is some later material and correspondence to 1979.
The collection contains laboratory notebooks and drawings associated with the design of the first cavity magnetron in 1939-40, and further notes, drawings, blueprints, reports, correspondence, committee papers, etc. relating to its subsequent development. There is also a series of reports of research teams in various universities, institutions and government departments in Britain and the USA, mainly concentrating on the theoretical problems posed by the magnetron. These teams included those led by D.R. Hartree at Manchester University and by E.C. Stoner at Leeds University; their reports appear at CSAC 68/6/79/D.5, CSAC 68/6/79/D.7, CSAC 68/6/79/D.9, CSAC 68/6/79/D.11, CSAC 68/6/79/D.13, CSAC 68/6/79/D.15, CSAC 68/6/79/D.17, CSAC 68/6/79/D.18, CSAC 68/6/79/D.19 and CSAC 68/6/79/D.6, CSAC 68/6/79/D.8, CSAC 68/6/79/D.10, CSAC 68/6/79/D.12 respectively.

The collection was received from Dr. Boot and his name therefore appears at the head of the catalogue, but other members of the team working on magnetrons at Birmingham also feature in the collection. In particular there is a substantial number of papers in Randall's hand or denoting his authorship
