Radiation Damage in Permanent Magnet Lenses
… magnet quadrupoles in their magnetic optics. Radiation exposure during radiography experiments is known to damage these lenses and degrade image quality. This effect is studied under controlled conditions, leading to the conclusion that nonuniform radiation damage is inherent to the quadrupole …

Modeling Radiation Damage in Nanostructured Ferritic Alloys: Helium Bubble Precipitation on Oxide Nanofeatures
… generation of nuclear reactors call for more radiation tolerant materials. One such material, nanostructured ferritic alloys (NFA) are a candidate material for use in cladding. The radiation tolerance of NFAs comes from the high number density of small oxide nanofeatures composed of Y, Ti, and …

Impact of cellular dislocation structures produced by additive manufacturing on neutron irradiation damage evolution in stainless steel 316L
… features and their potential impact on irradiation-induced damage mechanisms must be studied. Stainless steel 316L (SS-316L) samples were irradiated in the Advanced Test Reactor overa range of fast neutron fluences as part of a grant received by the Colorado School of Mines. …

3D detectors for synchrotron applications
3D detectors are a novel variety of photodiode radiation detector, invented by Parker, Kenney and Segal (1997). Instead of having n- and p-type contacts on the front and back surfaces of a silicon substrate, like a standard photodiode, they have columns of doped material passing through the …
