First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

Properties of toroidal Alfvén eigenmodes (TAEs), driven by neutral beam injection (NBI) hot ions, are described for the tokamak T-15 under construction in the Kurchatov Institute to test a possible influence on the beam and plasma particle losses. The T-15 baseline scenario with a 10-s flat-top 2 MA current stage, 6-MW NBI plus 6 MW of electron cyclotron resonance (ECR) heating is computed with the ASTRA code. The spatial structure and the frequencies of different TAE modes with the toroidal indexes n = 2 to 8 have been obtained with the ideal magnetohydrodynamic KINX code. The bulk plasma Landau damping, linear growth rates, and nonlinear evolution of the TAE mode amplitudes driven by the NBI ions have been computed with the VENUS code. Our numerical estimations for the T-15 TAE modes are compared with experimental and theoretical results for the DIII-D and NSTX tokamaks.
