Title: Implementation of Microcalorimeter Array Technology for Safeguards of Nuclear Material

Abstract

Safeguards of nuclear materials depends on both destructive and nondestructive assay (DA and NDA respectively). Ultra-high resolution microcalorimeter gamma spectroscopy has the potential to substantially reduce the performance gap between NDA and DA methods in determination of plutonium isotopic composition. This paper details the setup of a cryostat and microwave readout system for microcalorimeter gamma spectroscopy, the functionality of which has been successfully demonstrated.
