4101 Etcheverry Hall

Prof. Tatsuya Katabuchi and Prof. Toru Obara Toru Obara Abstract: Rotational Fuel-shuffling Breed-and-Burn reactor (RFBB) has been studied as a reactor that can achieve effective utilization of uranium resources and reduction of nuclear waste. In this talk, the concept of the RFBB and the current study of the start-up core design is introduced. Biography: Toru…

High fluence He irradiation of materials using Helium Ion Microscopy

4101 Etcheverry Hall

Gregor Hlawaceka Institute for Ion Beam Physics and Materials Research, Helmholtz—Zentrum Dresden—Rossendorf, 01328 Dresden, Germany Abstract: I will present some recent results on the high fluence irradiation of metals using gas field ion source (GFIS) based helium ion microscope (HIM)1 . High entropy alloys (HEAs) are a relatively new class of metal alloys composed of…

The early history of fusion discoveries, 1930s-1940s

Haviland Hall rm. 12

Dr. Mark B. Chadwick Chief Scientist & Chief Operating Officer for the Weapons Physics Associate Laboratory Directorate, ALDX, at Los Alamos Abstract: I will describe the early breakthroughs in determining DT and DD fusion cross sections in the 1940s. Berkeley played a key role in making tritium in the cyclotron for the first 1943 measurement…
