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.”

Two experiments directed to a search the experimental conditions for the creation of the hot plasma bunch with β~1 at the multimirror trap GOL-3-II are described. In the first one the hydrogen cloud of 0.5 m length and ~1016 density cm−3 was heated in a short (~ 0.5 m) section with relatively small magnetic field placed in the 12-m solenoid with 9 T magnetic field in mirrors. Plasma pressure was measured by diamagnetic loops and reached βvac ≈0.4. In the second experiment the dense bunch is created by pellet (LiD, (CH2)n) injection into the electron-beam-heated plasma. After beginning of the beam injection the pellet is evaporated and ionized, then dense plasma is magnetized and as result dense bunch (ne=1016-1017cm−3) with abrupt edges is created. After heating the bunch has expansion velocity up to 3·107cm/s.
