Dr. Raluca Scarlat joins the UCB Nuclear Engineering Faculty

January 31, 2019

Raluca O. Scarlat, a UC Berkeley Nuclear Engineering Ph.D. Alumna (2012), is returning as our newest faculty member. With a B.S. in Chemical Engineering from Cornell University (2006) also under her belt, she will be leading studies in Chemical and termophysical characterization of high-temperature molten salts and other inorganic fluids, and heat and mass transport pertaining to energy systems; Electrochemistry, corrosion, thermodynamics; Nuclear reactor safety analysis, licensing and design; and engineering ethics.

Welcome to the family, Raluca!

Abstract:

Since the 1932 discovery of cosmic ray positrons by C. D. Anderson and the 1934 discovery of beta decay positrons by Frederic and Irene Joliot-Curie, positrons have been used in a wide variety of experiments to find out how they interact with ordinary matter in its myriad forms. As a result, a number of unique and valuable positron probes are now available for determining the properties of inorganic matter and bio-materials. In a parallel development, the electron-positron atom (positronium) has been the subject of ever more precise measurements to look for unexpected departures from QED theory. Finally, since the first production of di-positronium molecules in 2007, it has been possible to make dense collections of positrons and positronium with the hope of soon being able to make a positronium Bose-Einstein condensate and observe its stimulated annihilation. A recent effort by a UCB-LANL-UCR collaboration to make 10× more intense 22Na positron sources at a reasonable cost is promising a revival in positron science in the USA.
