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.

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.


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.
