Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

WEST claims latest plasma confinement record
The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

Absolute neutron-capture cross-section measurements from 0.01 to 10 eV employing a Moxon-Rae detector and conventional time-of-flight techniques are described. For the calculation of multiple-scattering and gamma-ray attenuation effects in samples, new improved methods were developed. Cross-section curves were evaluated for the elements europium and lutetium as well as for the isotopes 151Eu, 153Eu, 175Lu, and 176Lu. The cross sections could be determined to an accuracy of better than 5%; however, for some resonance cross sections the total error increases up to 10%.
