An accelerator facility for intermediate energy proton irradiation and testing of nuclear materials

نویسندگان

چکیده

The bulk irradiation of materials with 10-30 MeV protons promises to advance the study radiation damage for fission and fusion power plants. Intermediate energy proton beams can now be dedicated within university-scale laboratories. This paper describes first such facility, an Ionetix ION-12SC cyclotron producing 12 beams. Samples are mm-scale tensile specimens thicknesses up 300 um, mounted a cooled beam target control over temperature. A specialized tester radioactive at high temperature (500+ {\deg}C) and/or vacuum represents conditions in systems, while digital image correlation system remotely measures strain. Overall, facility provides testing capability intermediate complement traditional in-core reactor micro-scale ion irradiation. demonstrates that is scalable effective approach nuclear research, down-selection, qualification.

Intermediate-energy Nuclear Data for Radioactive Ion Beams and Accelerator-driven Systems

Formation cross sections of isotopes produced in inverse kinematics from the spallation/fragmentation and fission of 197Au (at 800 A⋅MeV), 208Pb (at 1 A⋅GeV) and 238U (at 1 A⋅GeV) are presented. These data are extremely important for the design of acceleratordriven systems and new radioactive-ion-beam facilities. The data have been measured at GSI with the FRagment Separator, which allows preci...
