Penn publishes article on fused silica in Physics Letters A

Steven Penn, HWS assistant professor of physics, had an article published in the March 2nd issue of “Physics Letters A.”

His article, “Frequency and surface dependence of the mechanical loss in fused silica,” presents a model for the anomalously low mechanical loss in ultrapure fused silica.

This improved understanding of fused silica was a primary motivation for that material being chosen for the test mass mirrors in the next generation of the LIGO gravitational-wave observatories.
