Item type: Ítem , Access status: Acceso Abierto , Fabricación de detectores semiconductores de Si (Li) para reacciones nucleares(1969) Erramuspe, Hugo JuanSe presenta un método detallado para la fabricación de detectores de estado sólido de Si (Li) orientados al estudio de reacciones nucleares en el acelerador sincrociclotrón de la CNEA. Se describen técnicas novedosas para el control no destructivo de la profundidad de la zona de compensación total w mediante mediciones de capacidad diferencial de pulso, y un sistema electrónico automatizado para el control del proceso de drift actuando sobre el refrigerante fluorocarbonado FC-43.Item type: Ítem , Access status: Acceso Abierto , A Temperature Compensated Single Channel Analyzer for Monitoring Purposes(North-Holland Publishing Co., 1973) Hadis, R.This paper presents the design, construction, and evaluation of a thermally compensated single-channel analyzer (SCA) specifically conceived for the continuous monitoring of fission products in the primary cooling circuit of nuclear reactors (such as the CNEA’s RA-3 research reactor).Item type: Ítem , Access status: Acceso Abierto , Low-Level Radioactivity Measurements on Aluminum, Steel and Copper(Pergamon Press, 1972) Rodríguez Pasqués, Rafael Héctor; Steinberg, H. L.; Harding, J. E.; Mullen, P. A.; Hutchinson, J. M. R.; Mann, W. B.This paper presents the results of a comprehensive program to measure radioactive contamination levels in commercial samples of aluminum, steel, and copper from more than 30 industrial plants in North America and Argentina (SOMISA).Item type: Ítem , Access status: Acceso Abierto , Apparatus for the automatic plotting of magnetic hysteresis loops(1974) Fourcade, Juan Carlos; Esparza, Daniel AntonioA versatile and simple instrument for automatically measuring the magnetic characteristics of materials is described. The instrument is highly stable and sensitive, making it suitable for plotting the Rayleigh loops of samples weighing less than 1 g. Another useful design characteristic is the automatic plotting of some magnetic parameters as functions of secondary variables, for example, the dependence on temperature of the remanent magnetic flux.Item type: Ítem , Access status: Acceso Abierto , A cryostatic cell for polarised Raman studies(IOP Publishing, 1983) Halac, Emilia Beatriz; Gutiérrez, NorbertoA low-temperature cell for polarised Raman spectroscopy is described which facilitates the growing of single crystals from the liquid, and the determination of the orientation of the samples with the aid of X-ray diffraction.
