Scientists measure local vibrational modes at individual crystalline faults

Posted on Author Toby Comments Off on Scientists measure local vibrational modes at individual crystalline faults
Employing newly developed electron microscopy techniques, researchers have, for the first time, measured the spectra of phonons – quantum mechanical vibrations in a lattice – at individual crystalline faults, and they discovered the propagation of phonons near the flaws.

Machine learning improves particle accelerator diagnostics

Posted on Author Toby
Operators of Jefferson Lab’s primary particle accelerator are getting a new tool to help them quickly address issues that can prevent it from running smoothly. The machine learning system has passed its first two-week test, correctly identifying glitchy accelerator components and the type of glitches they’re experiencing in near-real-time. An analysis of the results of the first field test of the custom-built machine learning system was recently published.
