      abstract     = {A major challenge to understanding the response of
                      materials to extreme environments (e.g., nuclear fuels/waste
                      forms and fusion materials) is to unravel the processes by
                      which a material can incorporate atomic-scale disorder, and
                      at the same time, remain crystalline. While it has long been
                      known that all condensed matter, even liquids and glasses,
                      possess short-range order, the relation between
                      fully-ordered, disordered, and aperiodic structures over
                      multiple length scales is not well understood. For example,
                      when defects are introduced (via pressure or irradiation)
                      into materials adopting the pyrochlore structure, these
                      complex oxides either disorder over specific
                      crystallographic sites, remaining crystalline, or become
                      aperiodic. Here we present neutron total scattering results
                      characterizing the irradiation response of two pyrochlores,
                      one that is known to disorder (Er2Sn2O7) and the other to
                      amorphize (Dy2Sn2O7) under ion irradiation. The results
                      demonstrate that in both cases, the local pyrochlore
                      structure is transformed into similar short range
                      configurations that are best fit by the orthorhombic
                      weberite structure, even though the two compositions have
                      distinctly different structures, aperiodic vs.
                      disordered-crystalline, at longer length scales. Thus, a
                      material's resistance to amorphization may not depend
                      primarily on local defect formation energies, but rather on
                      the structure's compatibility with meso-scale modulations of
                      the local order in a way that maintains long-range
                      periodicity.},
