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.

An integrated zero-dimensional plasma-control code, ASH, has been developed and employed to study the possibility of controlling the burn condition of a fusion reactor of the International Thermonuclear Experimental Reactor type by modulating the refueling rate. A constant-gain proportional feedback controller is synthesized; the values of feedback gains are obtained by either pole placement or an design. Compared with the use of modulated auxiliary heating alone, modulation of the refueling rate can provide important additional leverage in tokamak burn control. A key feature of this system is the incorporation of robust control theory to allow for modeling uncertainties.
