46. Status of Ion Beam Irradiation at HIT Facility

Dr Eiichi Wakai

10/12/2019, 11:30

An optical transmission radiation (OTR) foil as beam monitor, which is Ti-15V-3Cr-3Al-3Sn alloy with 0.05 mm in thickness, used in the J-PARC neutrino facility was examined for the irradiation damage analysis in the Pacific Northwest National Laboratory under the RaDIATE collaboration. The foil was irradiated by 30 GeV proton beam with 1.4x10^20 POT. The foil microstructures of β-phase...

9. Blisters study in tungsten irradiated by MeV protons: Fracture morphology and mechanical properties

Mrs Inbal Gavish Segev (Soreq)

Oral presentation

Proton irradiation damage is a common problem in structural materials at accelerators and nuclear fusion reactors. This damage may result in the degradation of the mechanical properties of structural materials and jeopardize the safe operation of nuclear facilities. Tungsten and tungsten alloys are utilized as building blocks of nuclear facilities, due to their excellent mechanical and...

24. Characterization of radiation damage effects in high-energy neutrino target graphite using low-energy ion irradiation

Mr Abraham Burleigh (Illinois Institute of Technology, Fermi National Accelerator Laboratory)

10/12/2019, 12:20

Oral presentation

Neutrino targets are constantly irradiated by high-energy protons to produce secondary particles that decay into neutrinos. Over time, radiation damage effects the macroscopic physical and structural properties of target materials and result in shortened operation lifetimes. The resulting decrease in the material’s thermal shock resistance combined with greater embrittlement results in an...

3. Experimental investigation of radiation damage effects in beryllium: updates on recent results obtained on proton, neutron and He-ions irradiated samples

Dr Slava Kuksenko (United Kingdom Atomic Energy Authority)

10/12/2019, 12:45

Oral presentation

Beryllium is an essential material for target components material in the currently running (NuMI) and near-future multi-megawatt accelerator particle sources (LBNF), reflectors and moderators in material testing nuclear reactors, plasma facing material (JET, ITER) and potential neutron multiplier (DEMO) for fusion reactor designs, and it is under extensive investigation by fission, fusion...
