Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

Different strategies exist for electron multiplication in a proportional radiation gas detector. In this work, the amplification region is formed by an array of equipotential stainless steel wires that were fixed at equal distance from a bared silver flat ribbon cable as the anode of the detector. The wires in this structure have the same role as the micromesh in Micro-Mesh Gaseous (Micromegas) detectors. Its fabrication method is simple and low cost. In this work, the amplification gain of the fabricated sample at different anode voltages was extracted, and the maximum achievable gain without electric discharge was measured to be M = 315 at 700 V. The proposed detector has an inherently two-dimensional positioning capacity, and the position sensitivity of the detector in one dimension was tested, the results of which show a good discrepancy with theoretical expectation. For the fabricated detector, the maximum number of charges before electric discharge was extracted (1 × 107) and compared with the best-designed Micromegas detector (6 × 107). These results clearly show that the proposed detector, despite its simplicity and cost-effective process, has a reasonable quality in comparison to the Micromegas detector.
