PHYSICAL RESEARCH ‘ Cosmotron Repair Deaign of coil clamp hardware and accessories was substantially completed. The delays which occurred in the shipment of bare extruded copper conductors to Westinghouse, the fabricator of the new copper colls, makes it unlikely that coil installation can be completed before mid-November, Because of deviations from the specifications contained in the March invitation, the bids for shielding were rejected and new bids were invited and received on the basis of an increase in scope to include shielding for an external beam catcher. Despite these delays, it still appears possible to complete the coil repair and the installation of the shielding by the end of December 1958. COMPUTER RESEARCH AND DEVELOPMENT University of Chicago A contract was awarded to the recently established Institute for Computer Research ofthe her ‘ily vel = mit University of Chicago for the fabrication of a new transistor-type computer, and for related research and development. The institute is directed by Dr. Nicholas Metropolis, who designed the Los Alamos “Maniac” machines, CHEMISTRY Element 102 - The nuclide of element 102 having an atomic weight of 254 was produced at the University of California Radiation Laboratory through use of the Heavy Ion Linear Accelerator (HILAC). This nuclide has a half-life of three seconds. “on ar . Bombardment of curium 246 with highly ionized carbon 13 from the HILAC produced 5 neutrons and the nuclide 102". The latter was identified by the fact that it decayed into fermium 250 and an alpha particle. Fermium 250 emits an alpha particle of 7.43 million elec- tron volts (Bfev) and has a 30-minute half life. med, -nute .rget en TBYs era- Ion Exchange - Chemical compounds capable of exchanging ions have recently become available which are soluble in organic solvents but insoluble in water. Solutions of these compounds in organic media have been found to extract ions selectively from aqueous solutions. Thus, liquids may serve in a manner analogous to the more commonly used solid ion exchangers such as Dowex 50. The possibilities of this new method for selective extraction of various ions are being further explored. (End of UNCLASSIFIED section.)
