The papers contain laboratory notebooks and drawings associated with the design of the first cavity magnetron in 1939-1940, and further notes, drawings, blueprints, reports, correspondence and committee papers relating to its subsequent development. There are reports of research teams in various British and American universities, institutions and government departments, including those led by D.R. Hartree (q.v.) at Manchester University and E.C. Stoner (q.v.) at Leeds University. There are also a number of historical accounts of the development of the cavity magnetron.

Scope and Content
Administrative / Biographical History
Boot was a physicist who made an outstanding contribution to the successful application of British science during the Second World War. Working with J.T. Randall in M.L.E. Oliphant's laboratory at Birmingham University, Boot produced the first 10 centimetre radar through the cavity magnetron. a discovery which had a profound impact on the waging of the war in several important spheres. In the Battle of the Atlantic centrimetric radar provided the Allies with a means of locating with accuracy, surfaced U-boats in any weather, day or night, and centrimetric radar was also decisive in the defeat of the German night bombers in 1943-1944 and in the improvement in the accuracy of the Allies' own night bombing. The cavity magnetron was built by Randall and Boot during the winter of 1939-1940 and developed by research teams in universities, institutions and government departments in Britain and the USA. Randall and Boot were awarded the Thomas Gray Memorial Prize of the Royal Society of Arts in 1943 for 'improving the safety of life at sea'. Further recognition followed with the award by the Royal Commission for Awards for Inventors in 1949, the John Price Wetherill Medal of the Franklin Institute, Pennsylvania in 1958 and the John Scott Award of the City of Philadelphia in 1959.
