Event reconstruction in high resolution Compton telescopes
The development of germanium Compton telescopes for nuclear γ-ray astrophysics (∼0.2-20 MeV) requires new event reconstruction techniques to accurately determine the initial direction and energy of photon events, as well as to consistently reject background events. This paper describes techniques for event reconstruction, accounting for realistic instrument/detector performance and uncertaintie...
متن کاملThe GEANT Low Energy Compton Scattering (GLECS) Package for use in Simulating Advanced Compton Telescopes
Compton gamma-ray imaging is inherently based on the assumption of gamma rays scattering with free electrons. In reality, the non-zero momentum of target electrons bound in atoms blurs this ideal scattering response in a process known as Doppler broadening. The design and understanding of advanced Compton telescopes thus depends critically on the ability to accurately account for Doppler broade...
متن کاملGamma - Ray Telescopes 400 Years of Astronomical Telescopes
The last half-century has seen dramatic developments in γ−ray telescopes, from their initial conception and development through to their blossoming into full maturity as a potent research tool in astronomy. Gamma-ray telescopes are leading research in diverse areas such as γ−ray bursts, blazars, Galactic transients, and the Galactic distribution of Al.
متن کاملCompton Scattering
In the early 20th century, research into the interaction of X-rays with matter was an emerging field. It was observed that when a beam of X-rays is directed at an atom, an electron is ejected and the light is scattered through an angle θ, as illustrated below. Classical electromagnetism predicts that the wavelength of scattered rays should be equal to the initial wavelength; however, experiment...
متن کاملLiquid Mirror Telescopes: History
A history of Liquid Mirror Telescope (LMT) experimentation is provided. The concept can be traced to Ernesto Capocci of the Naples Observatory (1850), but it was not until 1872 that Henry Skey of the Dunedin Observatory in New Zealand constructed the rst working laboratory LMT. The 1909 experiments by Robert Wood at Johns Hopkins University exposed some of the strengths and weaknesses of the LM...
