Double Scatter Spectrum for the Multiplexed Compton Scatter Tomograph. MS thesis, AFIT/GAP/ENP/99M Graduate School of Engineering, Air Force Institute of . Compton scattering can be used to determine the electron densities of tissues for medical applications and those of materials for industrial applications. Much work has been devoted in solving the reconstruction problem. Norton proposed an analytic transform method for the reconstruction of Compton scattering tomography @J. Appl. Phys. 76, Abstract: Introduction: Compton scattering is a technique for determining the momentum distribution of electrons in condensed matter. When monochromatic photons are Compton scattered (inelastically scattered) in a fixed direction, the observed energy spectrum of the scattered photons is Doppler-broadened due to the motion of the target electrons.

  In the present work, we study the atomic Compton Scattering which could have great impacts on dark matter direct detection experiments. We give a quantitative analysis of the Compton scattering energy spectrum for Si and Ge atomic systems. The theoretical results on Compton scattering are calculated within the frameworks of free electron approximation (FEA) and relativistic . Moving beyond conventional attenuation-based imaging, Compton scatter tomography has also shown some promise for e.g., nondestructive evaluation applications [29] and materials characterization. an example spectrum). There has been recent interest in the use of energy sensitive detectors in tomography [4, 5], and in the present paper their application is key to the ideas presented. Our main goal is to show that the electron density may be reconstructed analyt-ically using the incoherent scattered data and to lay the foundations for a. the scattering angle and E 0 ˇkeV is the electron rest energy. Typically Compton scattering refers to the scattering of photons in the mid energy range. That is, the scattering of X-rays and gamma rays with photon energies ranging from 1keV up to 1MeV. Forward Compton scattering is the scattering of photons with scattering angles! ˇ=2.
