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.

The results of two integral experiments on carbon, performed at the Oak Ridge National Laboratory (ORNL) and at Intelcom Radiation Technology were compared with Monte Carlo calculations to test evaluated carbon neutron and gamma-ray production data sets. In both experiments NE-213 detectors were used to measure the angular dependence of neutron scattering and gamma-ray production from thick (1-mfp) carbon samples in the energy range from 0.5 to 20 MeV. Additional measurements from the ORNL experiment also provided angular-dependent energy distributions of the scattered neutrons. Multigroup Monte Carlo calculations modeling the two experimental arrangements were made to compare with the measured data. Both ENDF/B-III and ENDF/B-IV carbon data were used in the computations. The results indicate that such experiments are adequate for testing processed neutron scattering and gamma-ray production data (both integral and double differential) to within 10 to 20% over a wide range of incident neutron energies (1 to 15 MeV). Also, on the whole, calculations with the carbon ENDF/B-IV data compared favorably with the measured results over the energy range, tested. The only notable exceptions were the disagreements in the neutron result comparisons above 9 MeV, which were attributed for the most part to errors in the evaluated C(n, n’)3α and elastic angular distribution cross sections in this range.
