ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

Neutron imaging diagnostics are needed for understanding the principles of fusion ignition. Current experiments on the University of Rochester OMEGA laser facility and future experiments at the NIF require a new level of complexity in neutron diagnostics that has not yet been achieved. Previous shots have fielded a one dimensional pinhole array to gather an image of a sphere's neutron emission during the implosion. This one dimensional pinhole array that consisted of two pinholes on a plane was a challenging manufacturing task and was a substantial accomplishment for its time. Future neutron imaging diagnostics will require a two dimensional pinhole array to gather a more comprehensive set of data. This two dimensional pinhole array, consisting of 3 pinholes one three planes to form a 3x3 array of pinholes, added a new level of complexity to the manufacturability. A method for fabricating this pinhole array was developed and the finished instrument was fielded in July and October 2006. This paper describes the fabrication process to producing this pinhole array and shows some of the early data taken with it at the Omega facility.
