Proton Irradiation Creep in Pyrocarbon

[摘要] This project aims to understand irradiation creep in pyrocarbon using proton irradiation under controlled stresses and temperatures. Experiments will be conducted over a range of temperatures and stresses per the proposal submitted. The work scope will include the preparation of samples, measurement of deposition thickness, thickness uniformity, and anisotropy. The samples produced will be made in strips, which will be used for the creep experiments. Materials used will include pyrolytic carbon (PyC), Highly Oriented Pyrolytic Graphite (HOPG), or graphite strip samples in that order depending upon success. Temperatures tested under will range from 800?��C to 1200?��C, and stresses from 6MPa to 20.7MPa. Optional testing may occur at 900?��C and 1100?��C and stresses from 6MPa to 20.7MPa if funding is available.
