The effectiveness of small-bubble gas injection to mitigate cavitation-induced erosion damage and decrease strain in Spallation Neutron Source (SNS) target vessels was characterized using photography, laser-line scanning, in-situ vessel measurements. Observations from early targets showed that caused appreciable mass loss along the inner wall. Later designs incorporated a cavitation mitigation technique called injection, which small helium bubbles were introduced into flowing mercury during...

This paper uses of “The Road Runner” cartoon series as a starting point for mythico-rhetorical analysis message system contained cartoon. It explores how animated short re-enacts myth Sisyphus context post-World War II technological boom United States. Technology is source most cartoon, and created by failures technology.

A low temperature sample orientation device providing three axes of rotation has been successfully built and is in testing for use on several spectrometers at the spallation neutron source (SNS). Sample about vertical (ω) axis nearly 360° out plane tilts (ϕ v) from -3.4° to 4.4° -2.8° 3.5°, respectively, are possible. An off-the-shelf closed cycle refrigerator (CCR) mounted a room sealed rotary flange ω rotations sample. Out-of-plane made possible by piezoelectric actuated angular...
The SNS Project is a 1.4 MW accelerator-based neutron source located at Oak Ridge National Laboratory in Ridge, Tennessee. For shielding purposes, 5 meters of native soil backfill has been placed on top the accelerator tunnel system. This caused ongoing settlement tunnels. monitored by Survey and Alignment Group order to determine patterns deformation, when system will be stable enough for precise alignment beam line components. latest monitoring results indicate that rate significantly...
Optical tooling has been a mainstay of the accelerator alignment community for decades. Even now in age electronic survey equipment, optical remains viable alternative, and at times, only alternative. At SNS, we combine traditional methods, instrumentation, techniques, with more modern techniques. This paper details integration into world.
