THOMSON Thomson was born in Cambridge in 1892, into a family of scientific distinction on both sides. His father, Sir Joseph Thomson (always known as 'J.J.), was one of the foremost physicists of the a Director of the Cavendish Laboratory, work on the Third early collaborative research with him and having access through him fo current work After education at the Perse Schocl and Trinity College, Cambridge, electron. His son George was much guided and influenced by his father, conducting vision, and was elected a Fellow of Corpus Christi College in 1914. During the on the frontiers of knowledge, as his later historical writings frequently testify. Thomson's collaboration with his father continued for many years and included join c Cambridge, and in 1906 awarded the Nobe! Prize for Physics for his discovery of the Thomson began research in 1913 at the Cavendish Laboratory under his father's super- he shared with C.J. Davisson the Nobel Prize for Physics in 1937. First World War he was attached to the Royal Flying Corps at the Royal Aircraft most famous work was done, on electron diffraction by thin films ( 1926-28), for which Factory (later Establishment) at Farnborough, where he was a member of the famous ‘Chudleigh Mess' and formed lasting friendships with F.W. Aston, W.S. Farren, B.M. Jones, F.A. Lindemann (later Lord Cherwell), G.1. Taylor and others. At the end of the War he returned to Cambridge, and in 1922 was appointed Professor of Natural Philosophy at the University of Aberdeen. Here his G.P. Thomsen CSAC 75/5/80 In 1930, after a visit to America lecturing and working at Cornell, Thomson, now a Fellow of the Royal Society, moved to London as Professor of Physics at Imperial College. He continued work on electron diffraction and tried to develop it as a research tool for the study of surfaces, and also encouraged electron microscopy. A protracted illness which declared itself early in 1936 seriously interrupted his experi- mental work and marked the effective end of his work on electrons. Instead, he pursued the interest in nuclear physics begun a few years earlier, and in 1939 was quick to see the possible military implications of current work in nuclear fission. His professional knowledge, and his personal acquaintance with leading scientists ond government advisers enabled him fo initiate investigations, especially as (from April 1940) Chairman of the MAUD Committee which reported on the feasibility of an atomic weapon. During the Second World War, subsequent to his work on the MAUD Committee, and after two years at the Royal Aircraft Establishment, Farnborough, Thomson was sent as Scientific Liaison Officer to Canada, At this time, his wife at Imperial College. He was knighted in 1943. Under Thomson's guidance, work on an electrodeless the team the Air Ministry (1943-44). He resigned this post in December 1944 to resume work His scientific interests now centred on the study of cosmic rays and Kathleen was seriously ill in America; her death at the end of 1941 was a great blow He remained in Canada until summer 1942 after which he returned te Britain to him. to become Deputy Chairman of the Radio Board (1942-43) and Scientific Adviser to mesons, and on nuclear fusion - itself a development of a theory of an electrodeless discharge put forward by 'J.J.'. torus proceeded at Imperial College and was provisionally patented in 1946; subsequently transferred to the A.E.1. laboratories at Aldermaston, while similar work he died in 1975, A.E.1., ZETA at Harwell - which attracted much attention when they were brought as Master; he remained there until 1962 and spent his retirement in Cambridge, where was also ir: progress at Harwell. Both groups produced an apparatus - SCEPTRE al to the notice of the general public in 1958. In 1952 Thomson returned to Corpus Christi College, Cambridge, G.P.

Of considerable interest are the drafts and text of Thomson's autobiography covering his career to 1966; this document, which he had written primarily for his family, is included at A.2 - A.14 and has, with permission, been drawn upon in compiling some of the catalogue entries. is an important source It of information for some of the 'gaps' in the surviving manuscripts, particularly for such matters as Thomson's activities in the Second World War (other than the MAUD Committee), his many foreign visits and his public commitments. In his introduction to the autobiography, Thomson mentions his inability to write adequately of his wife Cathleen, and of his hope to compile a selection of her letters to him; bound copies of the autobiography, and of the letters, have been made available by Mr. D.P. Thomson and appear at A.14, A.14A respectively. f may .

Material relating to his historical and biographical writings on 'J.J.' can be found in the collection of papers of J.J. Thomson (CSAC no. 74/4/80) in the Library of Trinity College, Cambridge. In addition to an historical awareness, Thomson was also conscious of the impact of science on many aspects of life and thought. Section H groups together his lectures and writings on science-related topics of this kind: j g Pp it includes inter alia material on his work for the Voluntary Euthanasia Society which occupied much of his interest in his later years. y, LOCATIONS OF OTHER MATERIAL Thomson's original electron diffraction camera was deposited in p the Science Museum, London, in 1948 (see J.107). family hands.

Thomson CSAC 75/5/80 SECTION C — ELECTRON DIFFRACTION C.1 - C.45 In 1922 Thomson was appointed as Professor of Natural Philosophy in the University of Aberdeen, where he remained until 1930 when he went fo succeed H.L. Callendar as Professor of Physics at Imperial College, London. It was at Aberdeen that Thomson did his famous electron diffraction experiments which led to his sharing the Nobel Prize for Physics with C.J. Davisson in 1937. The research notes and notebooks in this Section document much of this work together with his earlier research at Aberdeen on positive rays. On moving to Imperial College Thomson continued to study electron diffraction and tried to develop it as a technique for the study of surfaces. His experimental work was interrupted by illness at the beginning of 1936 by which time he was already becoming interested in the study of neutrons which had been introduced to Imperial College by P. B. Moon soon after his arrival (see Section D); it was to this study that he returned when Fand G. he was able to resume work in 1938, Lectures on electron diffraction are to be found in Sections See also Section K for slides of electron diffraction experiments.

Del “= p28 Nuclear physics and the MAUD Committee D.29 - D.78 Second World War: other activities NUCLEAR PHYSICS AND THE MAUD COMMITTEE According to Thomson's autobiography (A.7) his interest in nuclear physics stemmed from the arrival of P.B. Moon at Imperial College in ‘about 1932', Moon introduced the study of neutrons to the laboratory soon after their discovery by Chadwick, and Thomson's early work on this subject is documented at D.1 ~ D.4; on his return fo Imperial College in 1938 after two years of illness he collaborated with Moon in attempts to measure slow-neutron velocity distributions and absorption coefficients (see D.5, D.6). e f g g 9g ©&xp : p y obtained using natural uranium the military implications of this. oxide and ordinary water or paraffin, to establish that a chain reaction could not be easily He asked Air Marshal Sir Wilfred Freeman for a In the spring of 1939 work on nuclear fission in various parts of the ton of uranium oxide for conducting experiments at Imperial College and proceeded world suggested that the release of an enormous amount of energy from uranium by means of a chain reaction might be a real possibility. Thomson was quick to realise as copies of the MAUD Committee reports of July 1940, various notes of meetings and The work was interrupted when Thomson went to Farnborough on the outbreak of the Second World War (see D.30 - D.34), but his interest in the problem was reawakened in early 1940 by the claim of ©.

Thomson CSAC 75/5/80 Thermonuclear research ‘By the beginning of 1946,' wrote Thomson in his autobiography (A.9) 'my own interest was turning to the possibility of the controlled emission of nuclear power from the (relatively) heavy isotopes of hydrogen; what is now called thermonuclear energy.‘ The initial work was done at Imperial College in collaboration with M. Blackman with whom Thomson filed a provisional patent for ‘Improvements in or relating to high temperature systems' in 1946 (see E.75). By 1947 considerable progress had been made in theoretical and small-scale experimental research, and Thomson felt ready to initiate a full-scale project, requiring more extensive facilities . than Imperial College could provide. Related research was already in progress at the Atomic Energy Research Establishment (A.E.R.E.), Harwell, so Thomson approached T.E. Allibone, Director of the newly-established Research Laboratory of Associated Electrical Industries Limited (A,E.1.) at Aldermaston. Some aspects of the ensuing negotiations are documented in E.88 - E.90; the Imperial College group finally moved to Aidermaston in 1951 and a programme of research was started which led to the production of the apparatus known as Sceptre III in autumn 1957. The Aldermaston be found at E.91 - E.105. Most of the thermonuclear work ceased to be secret after the simul- a similar apparatus produced by Harwell. Thomson subsequently became less directly group worked in close cooperation with Harwell throughout its existence; several involved with thermonuclear research and his active participation finally ceased in minutes of progress meetings, at which Thomson was also in regular attendance, are fo taneous publication in January 1958 of accounts of the work with Sceptre If and Zeta, See F.150 - F.209 for further material on thermonuclear energy. g) (E.1 - E.70) is particularly interesting in view of the secrecy restrictions which allowed produced for limited circulation as Harwell research reports (see, e.g., E.34, E.35). him to publish so little (but see F.114, F.115), although some of his drafts were re- 1963 when A.E.1. decided to close down the Aldermaston Laboratory.

F.36~ F.61 are almost all on electron diffraction, his own experimental research (for which he shared with C.J. Davisson the Nobel Prize for Physics in 1937) and the wave=particle theory of matter; the number of these, and the range of places at which Thomson was asked fo speak, show the international recognition of his work. deal with the practical applications of electron diffraction, and the electron micro~ scope, as tools of research. Several items, F.66 (F.188 et seq. After the Second World War, Thomson continued to write and lecture on the electron, and also on cosmic rays, mesons, and atomic structure, The advent of nuclear, and later of thermonuclear power, however, provided the chief matter of his scientific research and publications, crowded cluster of items ~ including several broadcasts - on the nature and conito! of nuclear energy, followed by a similar output at F.169 - F.174 on the then new implications of the hydrogen bomb.
