Slow Control System for a NEXT-TPC prototype

A. Gil; M. Ball; S. Carcel; J. Diaz; N. Yahlali 2009 16th IEEE-NPSS Real Time Conference, 2009

NEXT is a double beta decay experiment that will be installed in Canfranc Underground Laboratory. The precise monitoring of a number of variables such as temperatures, relative and absolute pressure, gas flows, high voltage, etc is required for the proper operation of the detector and to perform the adequate data corrections. For this purpose a complete Slow Control System using ...


Effect of anode shapes on neutron emission from a repetitive plasma focus device

F. Malik; S. M. Hassan; R. S. Rawat; M. V. Roshan; T. Zhang; S. Mahmood; J. J. Lin; T. L. Tan; P. Lee; H. Schmidt; S. V. Springham 2007 16th IEEE International Pulsed Power Conference, 2007

The conventional tapered anode of the NX2 repetitive plasma focus device has been changed to two other shapes (straight and spherical) to investigate the effect of anode shape on neutron emission characteristics of the device. The newly designed beryllium counter and 3He proportional counter are used for estimation of neutron yield and time resolved neutron emission characteristics are measured using ...


A life is short, a half-life is forever

Daniel E. Geer; Daniel G. Conway IEEE Security & Privacy, 2010

It is observed that when something undergoes a constant relative rate of change, there's an exponential function behind the observation. This paper explains that for exponential declines, we tend to report the half-life; think radioactive decay.


Performances of a method for reconstructing the energy of neutrons detected by a double scattering spectrometer

M. Agnello; E. Botta; T. Bressani; D. Calvo; P. Gianotti; F. Iazzi; C. Lamberti; B. Minetti; E. Balocco Conference Record of the 1991 IEEE Nuclear Science Symposium and Medical Imaging Conference, 1991

A neutron spectrometer based on the double scattering technique has been designed and built at the Laboratorio Tecnologico of INFN-Turin (Italy) for cold fusion experiments. The operating principle for the reconstruction of the energy can be applied to various fields (neutron emission from sources, fission and fusion) and is described together with the tests performed. A resolution of less than ...


Positron emission tomographic images and expectation maximization: a VLSI architecture for multiple iterations per second

W. F. Jones; L. G. Byars; M. E. Casey IEEE Transactions on Nuclear Science, 1988

A digital electronic architecture for parallel processing of the expectation maximization (EM) algorithm for positron-emission-tomography (PET) image reconstruction is proposed. Rapid (0.2-s) EM iterations on high-resolution (256*256) images are supported. Arrays of two VLSI chips perform forward and back projection calculations. The architecture is described, including data flow and partitioning relevant to EM and parallel processing. EM images are shown ...

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.
