Division Spotlight
Decommissioning & Environmental Sciences
The mission of the Decommissioning and Environmental Sciences (DES) Division is to promote the development and use of those skills and technologies associated with the use of nuclear energy and the optimal management and stewardship of the environment, sustainable development, decommissioning, remediation, reutilization, and long-term surveillance and maintenance of nuclear-related installations, and sites. The target audience for this effort is the membership of the Division, the Society, and the public at large.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Experiments were carried out in the neutronoptimized mode of the plasma focus operation with small electrode diameters and condenser bank energies of 250, 390, and 490 kJ. The time sequence of the emitted radiation (neutron and gamma) was realized by the time-of-flight (TOF) method using an NE-102A plastic scintillator and silicon detectors viewing X rays from the plasma exclusively. The detectors were operated in the wide-energy window mode. Special attention was given to the interpretation of neutron TOF traces and their comparison with the absorption analysis and previously measured spectra by nuclear plates. The usefulness of gamma rays emitted by (n, n′γ) processes in electrodes is shown to be a precise indicator of the time evolution of the neutron emissivity. These conclusions are based on many shots that were statistically analyzed. Average values are discussed simultaneously with the results of representative single shots. It was found that two (sometimes more) neutron bursts are typical and, in each case, are accompanied by simultaneous hard X rays. The maxima of emissivities coincide with the dI/dt maximum. A theoretical analysis of the results reveals the existence of long time-confined streams of fast electrons and deuterons (effective energy ∼80 keV) with evidence of their slowing down.
