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.”

Non-inductive lower hybrid current drive (LHCD) experiments have been carried out on the Alcator C-Mod tokamak and the hard x-ray (HXR) spectrum has been measured. An improved analysis technique of the experimental HXR data has been developed to more accurately evaluate the HXR flux for this type of discharge. We have simulated a similar LHCD discharge with the full wave code LHEAF (Lower Hybrid wavE Analysis based on FEM). This code, combined with the newly developed 3D Fokker-Planck (v∥, v⊥, r) and synthetic HXR diagnostic modules, to calculate the steady state electron distribution function in the plasma and the resulting HXR radiation spectrum. The simulated non-thermal x-ray proflle shave been found to be in good agreement with the measured experimental profile. In particular LHEAF simulations were able to reproduce the broad width of the measured HXR profile for a discharge with low n∥, which has been a long standing issue for LHCD simulations on Alcator C-Mod.
