Induction linear accelerators for physics diagnostics

The short pulse, very high current capabilities of the induction linear accelerator make it a logical candidate for certain applications to diagnosing physical properties. Two examples are fast high density explosive experiments and material science using neutron scattering. Flash x-rays are needed for imaging high density metal compression experiments. The short (50-75ns) pulse-burst capabilities of the induction linac are well suited to this. Because high x-rays doses are necessary to image the experiment and characterize density variations the multi-kiloampere capabilities of induction machines are attractive. Short neutron pulses from proton induced spallation can provide excellent energy and time resolution in material studies using neutron scattering. The induction linac simplifies spallation sources by transporting and accelerating the total beam current necessary (amperes of H+) in a single beam with no storage. Concepts for both applications are discussed with emphasis on technical risks and costs. (author)
