Inkjet droplets of radioactive material enable quick, precise testing at NIST
Researchers at the National Institute of Standards and Technology have developed a technique called cryogenic decay energy spectrometry capable of detecting single radioactive decay events from tiny material samples and simultaneously identifying the atoms involved. In time, the technology could replace characterization tasks that have taken months and could support rapid, accurate radiopharmaceutical development and used nuclear fuel recycling, according to an article published on July 8 by NIST.

A simple fusion experiment for the production and control of deuterium-tritium-ignited plasmas for scientific study is considered. The basic elements of fusion product alpha-particle behavior at ignition are analyzed. Alpha-particle containment is rather high even with the assumption of significant levels of toroidal asymmetries. Production of thermally stable plasmas is possible because of the low-beta thermal damping provided by electron cyclotron emission. The stability of internal kink modes, high-number ballooning modes, and toroidicity-induced shear Alfvén eigenmodes is investigated in the presence of fusion alpha particles. These modes can be either stable or unstable depending on the selected operational regime at ignition.
