NAVI-2: A ruggedized portable radiation analyzer

摘要

The NAVI-2 is a rugged, lightweight, and waterproof portable radiation analyzer developed by the Advanced Nuclear Technology group at Los Alamos National Laboratory. It was originally developed for a specific application: performing confirmatory measurements on plutonium removed from dismantled nuclear weapons as part of the O'Leary-Mikhailov mutual reciprocal inspections agreement. Since that time the hardware has stabilized into a mature package while several additional software packages have been developed. Now, in addition to the original software for performing confirmatory measurements, software is available that will allow the NAVI-2 to be used for scanning of extended sources, searching for hidden sources, and monitoring of items in a portal monitoring sense. This report will provide hardware and software details for owners and users of the NAVI-2.
