e ue temperatures a few degrees above absolute zero, These currents may be controlled by a magnetic field that can quench the current by Introducing electrical resistance, The electrical engineering problems are new, ‘From a theoretical standpoint, a computer operating at cryogenic temperatures offers the promise of compactness, reliability, and economy coupled with an effective increase in capacity and speed, resulting from the fact that many basic operations can be performed simultaneously, With respect to these characteristics, such a computer would be more like a human brain than are existing computers. “The research work on certain computer components is being carried out under contracts with Duke University and the General Electric Company, working in collaboration, (End of UNCLASSIFIED section.) hom CHEMISTRY RESEARCH bons hdEs ats tyet 4 rere oyomf “By BN OE % PHYSICAL RESEARCH Activation Anziysis (UNCLASSIFIED) Semiroutine analytical methods for measurements as low 2s parts-per-billion have been developed for determining the content of argon, xenon, and krypton in gas and liquid samples. The principle used is based on thermal neutron activation. NUCLEAR STRUCTURE AND NEUTRON PHYSICS RESEARCH The total neutron cross section of neptunium 237 was measured over.an energy range from 2 to 40 electron volts using a neutron velocity selector installed at the Low Intensity Testing Reactor at OckE Ridge. 46 DOE ARCHIVES |
