Thick-target Neutron And. Gamma.-ray Yields Induced by Medium-energy Proton and Deuteron Bombardments


Book Description

Stopping samples of Lucite, Al, Fe, and 238U (Fe, and 238U) were irradiated with 330 MeV deuterons (260 MeV protons). For each target, neutron energy spectra and prompt .gamma.-ray yields were measured using the time-of-flight technique. The detector was a right cylindrical volume of deuterated benzene, 12.5-cm diameter x 7.5-cm long, located at 110° to the incident beam direction. The neutron yield and the prompt .gamma.-ray yield were found to depend upon the atomic number of the target and upon the incident projectile. The measured shape of the neutron energy spectrum was not strongly dependent on either the incident projectile or the target atomic number. A lower limit for absolute neutron yields was also obtained.













Development of a Reference Database for Particle Induced Gamma Ray Emission (PIGE) Spectroscopy


Book Description

Ion beam analysis techniques are non-destructive analytical techniques used to identify the composition and structure of surface layers of materials. The applications of these techniques span environmental control, cultural heritage and conservation, materials and fusion technologies. The particle-induced gamma-ray emission (PIGE) spectroscopy technique in particular, is a powerful tool for detecting light elements in certain depths of surface layers. This publication describes the coordinated effort to measure and compile cross section data relevant to PIGE analysis and make these data available to the community of practice through a comprehensive online database.

Cyclotron Produced Radionuclides


Book Description

Application of radioisotopes has shown significant growth in the past decade, and a major factor contributing towards this growth is the availability of a large number of cyclotrons dedicated to the production of radioisotopes for medical applications. Although there are many articles in journals on cyclotrons and their use for radioisotope production, there is no single source of information for beginners on radioisotope production using cyclotrons. This publication attempts to address this deficiency. Its contains chapters on accelerator technology, theoretical considerations of nuclear reactions, the technology behind targetry, techniques on preparation of targets, irradiation of targets under high beam currents, target processing and target recovery.
