Diving board proposal
Use a 2 MeV Xenon beam to irradiate a diving board that is machined out of 2 mm UO2 pins from INL.
1.) An arcticle that measured how the strength of UO2 changes with temperature and grain size. The strength and fracture of stoichiometric polycrystalline UO2 , A.G.EvansR.W.Davidge, Journal of Nuclear Materials Volume 33, Issue 3, December 1969, Pages 249-260
In Situ material radiation damage measurement
Using a positron beam one can monitor the surface damage produced by an ion beam on a material.
Using photon induced positron annihilation you can adjust the penetration depth of the photon to scan the bulk material more. This would allow you to measure neutron damage as it occurs using MeV energy photons. By changing the energy of the photon you change the depth of the probes measurement.
References
Use 2 MeV protons to irradiate zirconium to study the temperature dependence of the initial recombination. The incident proton causes surface damage on the zirconium during the ballistic phase knout out. Recombination occurs afterwards and can be temperature dependent.
