	Lead is typically used as the initial target in a design for beam dumps for high energy electron beams (>20 MeV). Electron beams with energies above 20 MeV are usually built within concrete bunkers and therefore the design of any beam dump would just be a lead block (very cost effective) as close to the electron source as possible, after a vacuum flange of some sort. In a study of a hypothetical 100 MeV electron beam inside a concrete bunker with an extremely low dose rate constraint outside the bunker, the thickness of lead required would have been too restrictive for a compact design. In this study we investigate the potential benefits of designs that incorpo-rate low Z materials like graphite as the primary target material in vacuum followed by progressively higher Z materials up to lead. The results show the more diffuse elastic scattering from the primary target reduces the back scattered photons and reduces the overall neutron genera-tion. The effect was a more compact design for the beam dump to meet the same dose rate constraint.

Study of Material Choice in Beam Dumps for Energetic Electron Beams

Lead is typically used as the initial target in a design for beam dumps for high energy electron beams (>20 MeV). Electron beams with energies above 20 MeV are usually built within concrete bunkers and therefore the design of any beam dump would just be a lead block (very cost effective) as close to the electron source as possible, after a vacuum flange of some sort. In a study of a hypothetical 100 MeV electron beam inside a concrete bunker with an extremely low dose rate constraint outside the bunker, the thickness of lead required would have been too restrictive for a compact design. In this study we investigate the potential benefits of designs that incorpo-rate low Z materials like graphite as the primary target material in vacuum followed by progressively higher Z materials up to lead. The results show the more diffuse elastic scattering from the primary target reduces the back scattered photons and reduces the overall neutron genera-tion. The effect was a more compact design for the beam dump to meet the same dose rate constraint.

ANSTO currently operates the Australian Synchrotron, a 3 GeV, 3rd generation light source that begun user operations in 2007. The Australian synchrotron is now halfway through its expected life span and we have begun planning the next light source facility that will eventually replace it. This paper describes the conceptual design of an entirely new light source facility for Australia, which makes use of the latest advances in compact acceleration technology and 4th generation lattices.
