Dr. Ray Radebaugh is a NIST Fellow Emeritus with the Applied Chemicals and Materials Division. He joined NIST in 1966 as a post doc for the first two year and stayed on in a permanent position since then. He was the leader of the Cryogenic Technologies Group from 1995 until his retirement in 2009. His research focused on cryogenic refrigeration and material properties. He has taught short courses on cryocoolers since 1981.
Ronald G. Ross, Jr. received the doctoate degree in mechanical engineering from the University of California, Berkeley, USA, in 1968.,He then joined NASA's Jet Propulsion Laboratory (JPL), Pasadena, CA, USA, initially working on large area roll-up solar arrays for spacecraft. When the energy crisis of the mid 1970s occurred, he switched over to terrestrial photovoltaics (PV), where he became the Engineering Sciences and Reliability Manager of the United States Department of Energy (DOE) Flat-Plate Solar Array Project at JPL. Tasked with bringing PV into economic competitiveness for terrestrial power generation as part of DOE's National Photovoltaics Program, he spent the next 15 years leading the development of the engineering and reliability technology base for flat plate PV modules and arrays. Since that time, he has served as a multi-discipline technical manager and project engineer on a wide variety of projects where he specialized in bringing emerging advanced technologies to application readiness. He has authored or coauthored over 190 formal reports and journal articles covering the diverse disciplines of PV, reliability physics, electronic packaging and solder fatigue, cryocooler design and performance, and cryogenic instrument design. He retired from JPL in 2006 but continues to work part time as a JPL consultant.
