The Chairman of the United States Atomic Energy Commission (Lilienthal) to the Chairman of the Joint Congressional Committee on Atomic Energy (McMahon)
Dear Senator McMahon. At our meeting with the Joint Committee on February 4, 1949,1 interest was expressed in the present status of the program, about which the Committee was informed on October 5, 1948,2 for securing the cooperation of other countries in control of exports of important atomic energy materials and equipment to the U.S.S.R. and its satellite areas.3 Interest was also expressed in the extent to which this program has thus far been successful in preventing or controlling the export of mass spectrometer [Page 431]type instruments from the United Kingdom in view of information which had reached the Committee to the effect that Metropolitan Vickers, Ltd. in England is manufacturing and exporting this type of equipment.
There is enclosed a report from the Director of Production outlining the present status of the program through which export control action by other countries is being sought. As the Committee was informed in our letter of October 5, 1948, this program has been undertaken by the Department of State and the Department of the Army with the advice and assistance of the Commission.
As a result of the close working relationships established with the United Kingdom through the Combined Policy Committee, the Commission is in current consultation with the British on these problems and we have been assured that any requests for export of mass spectrometers from England will be discussed with us. In response to the Committee’s expressed interest in Metropolitan Vickers, specific inquiries have been instituted through appropriate British authorities to obtain an up-to-date report on the status of manufacture and export of mass spectrometer type instruments by this company and others in the United Kingdom. Preliminary information from the British is that no mass spectrometers of any kind have been exported from England by any company at any time. The British have been alerted to the possibility of a request from the Asiatic Petroluem Corporation, whose application to export a mass spectrometer from the United States was recently denied.
The Commission will continue to keep the Committee informed of significant developments in these fields.
