Darleane C. Hoffman, transuranium element pioneer, dies at age 98
Nuclear chemist Darleane D. Hoffman, who was renowned for her research on transuranium elements that advanced the understanding of nuclear fission, died on September 4 at her home in Menlo Park, Calif. She was 98.
Iowa origins: Hoffman was born on November 8, 1926, in Terril, Ia. She attended Iowa State University, where she earned a bachelor’s degree in chemistry in 1948 and a doctorate in physical (or nuclear) chemistry in 1951. She then began working as a chemist at Oak Ridge National Laboratory.

Magnetic effect of ferritic steel board (FB) on the plasma was experimentally investigated in the JFT-2M tokamak. Clear deterioration by the error field was not observed even in the condition of toroidally unbalanced placement of FBs outside vacuum vessel (VV). Deteriorating effects were not observed with the FBs inside VV for the operational region and the control of plasma, although slight discrepancy in the relation of vertical-coil current and equilibrium was found. Compatibility of FBs with high normalized-beta plasma (βN up to 2.7) was demonstrated after boronization.
