Development of a thin film 9.17 MeV gamma ray production target for the contraband detection system

S. T. Melynychuk; R. Meilunas Proceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 1999

We will describe the development of a thin film 13C target for generating 9.17 MeV gamma rays via a (p,γ) reaction for use in a commercial contraband detection system (CDS) employing nuclear resonance absorption. The target required for this system must consist of a thin 13C film backed by a high Z proton stopping layer. It must be able to ...


Image Reconstruction and Noise Evaluation in Photon Time-of-Flight Assisted Positron Emission Tomography

Takehiro Tomitani IEEE Transactions on Nuclear Science, 1981

In positron CT, the path difference of annhilation pair gamma rays can be measured by time-of-flight (TOF) difference of pair gamma rays. This TOF information gives us rough position information along a projection line and will reduce noise propagation in the reconstruction process. A reconstruction algorithm for TOF-positron computed tomography (PCT) based on the back- projection with 1-dimensional weight and ...


Study of hole-type gas multiplication structures for portal imaging and other high counting rate applications

J. Ostling; A. Brahme; M. Danielsson; T. Francke; C. Iacobaeus; V. Peskov 2002 IEEE Nuclear Science Symposium Conference Record, 2002

We performed studies of operation of various hole-type gas multiplication structures (GEM, capillary plates and others) at very high fluxes of X-rays (<60 keV - brehmstrahlung) and pulsed gamma radiation (< 50 MeV bremsstrahlung). In the case of X-rays the counting rate was 105-106 Hz/mm2 and in the case of gamma it reached up to 109 Hz/mm2 during the pulses. ...

M. Jentschel; P. Becker; J. Krempel; B. Lauss; G. Mana; P. Mutti 2008 Conference on Precision Electromagnetic Measurements Digest, 2008

Precise wave length measurements of gamma rays emitted after thermal neutron capture reaction allow the determination of the neutron's binding energy within a nucleus. Comparing this energy to atomic mass measurements gives direct access to the molar Planck constant NAh. This result will be of utmost importance in the context of a re-definition of the kilogram via the Planck and ...

  • Detection and Estimation of Radiological Sources

    This chapter considers several inferential problems regarding radiological sources, including estimation of point and distributed sources using a collection of static observers and source search and estimation using mobile observers. It presents the detection and localization of radiological materials that emit gamma rays, the highly penetrating electromagnetic radiations that can travel large distances through air. The chapter devotes to batch estimation of point radiological sources using measurements from a fixed network of sensors. The Bayesian approach to inference assumes that the unknown parameter of interest is a random variable. In this framework, inferential procedures are based on the posterior distribution, that is, the distribution of the parameter conditional on the observations. Bayesian estimation was favored because of the possibility of developing accurate and computationally efficient approximations of optimal Bayesian estimators for large dimensional parameters. The Renyi divergence is only one of a number of candidates for measuring the difference between two distributions.

  • 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.
