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.”

In the GAMMA10 tandem mirror, the first pellet injection experiments in open systems have started.1 The tandem mirror machine is suitable for measuring propagation of pellet-fueled particles along the magnetic field lines. We observed a very low frequency oscillation in various diagnostic signals from the plasmas with a pellet injection. The frequency of the oscillation is a few hundred Hz. It is found that the phase of those signals changes to anti-phase at a certain place. The oscillation continued during plug-ECH for the formation of confining potential and its amplitude decays within a several ms after the end of ECH pulse. Measurements at several locations along the field lines indicates that this oscillation is a standing wave along field lines of plasma density perturbation due to the pellet injection. The wavelength of the oscillation is estimated to be about 6m. The oscillation has mode number n = 3.
