iii John 4. Derry -l- ~" September 11, 1950 from the AEC and AEC contractor organizations will attend the symposium. The acenda for this conference lists papers to be presented by outstanding authorities, among whom is Dr. Yeorge V, Taplan, of the Atomic snersy Froject at the University of California at bos Angeles, the developer of one type of chemical dosimeter. Civilian Defense A meetins was held with ‘ir. Vincent B, Lamoureux of the NSRB to discuss the many letters “hich the Nadiation Instruments Branch is receiving concerning instrumentation for civilian defense purposes, Our present volicy in answering these letters was discussed and was considered to be adequate. However, in some cases it was decided to refer the letters directly to the WSRS for reply when the questions pertain to material outside the jurisdiction of the AEC. The civilian defense monitorinz instrument developed by the New York Operations Office was tested at the Bureau of Standards for energy dependency and at rort sionmouth, New Jersey for ruggedness and climatic dependency. «although only incomplete tests data are available, the instrument avpears to be quite adequate with regard to energy dependency and ruggedness. Special Zlectron Tube Development Program The Steering Committee of the Atomic Energy Commission's Speciai Tube Devalopnent Program met in Princeton, New Jersey on August 41 and Sep- tember 1 for the vurpose of formulating a program of research and dev- elopment to be conducted by the Research Laboratories of the Radio Corp- oration of -imerica under AEC contract. Bureau of Ships representatives attended a portion of the sonference and a orogram of information ex- change and contract coordination was evolved. A decision was made that the research activities should center around the development of two types of new ghotomultiplier tubes -- one, a large cathode area device for use as a samma spectrometer, and the other a high gain fast tube for general use in the analisis of nuclear radiations. It was also decided to in- vestigate the feasibility of a tube for application as a pulse height analyzer. Murine the meeting it became anparent that there is need within the AEC for a panel to coordinate the research and development of electron tubes ia general. It was recommended that this group be similar in nature and function to the Panel on Slectron Tubes under the Research and Vevelop- ment Board of the Ni. The Instruments Branch was asked to investigate the reactions to this suzgestion and the feasibility of establishing such a Zroud. DOS ARCHIVEL
