The Cantilever Beam Method for Simulating Irradiation Creep and Growth

The deflection of zirconium alloy cantilever beam specimens during irradiation with 100 keV neon ions can be correlated with creep and growth measurements performed on neutron irradiated specimens. The deflection of these cantilever beam specimens is measured by noting the shift in position of a laser beam reflected from a mirror attached to the free end of each specimen. The apparatus and method developed to make deflection measurements on specimens at elevated temperatures under vacuum in the target chamber of a mass separator is described. The physics of the technique is also described and applied to deflection versus ion fluence data obtained from flux cycling experiments on cold-worked and stress-relieved Zr-2.5 wt% Nb.
