Measuring the electron neutrino mass using the electron capture decay of 163Ho
Joel Ullom, Daniel Schmidt, Simon Bandler +14
While the mass differences between neutrino mass states are known, their absolute masses and mass hierarchy have not yet been determined. Determining the mass of neutrinos provides…
Improved Nondestructive Isotopic Analysis with Practical Microcalorimeter Gamma Spectrometers
Mark Croce, Daniel Becker, Katrina E. Koehler +1
Advances in both instrumentation and data analysis software are now enabling the first ultra-high-resolution microcalorimeter gamma spectrometers designed for implementation in nuc…
First Measurements of Nuclear Detonation Debris with Decay Energy Spectroscopy
Mark P. Croce, Katrina E. Koehler, Veronika Mocko +4
We report the first isotopic composition measurements of trinitite, nuclear detonation debris from the Trinity test, using the novel forensics technique of decay energy spectroscop…
Measurement of Ac227 Impurity in Ac225 using Decay Energy Spectroscopy
Aidan D. Tollefson, Chandler M. Smith, Matthew H. Carpenter +10
225Ac is a valuable medical radionuclide for targeted alpha therapy, but 227Ac is an undesirable byproduct of an accelerator-based synthesis method under investigation. Sufficient…
Improved Plutonium and Americium Photon Branching Ratios from Microcalorimeter Gamma Spectroscopy
Michael D. Yoho, Katrina E. Koehler, Daniel T. Becker +15
Photon branching ratios are critical input data for activities such as nuclear materials protection and accounting because they allow material compositions to be extracted from mea…
First Calorimetric Measurement of Electron Capture in Pt with a Transition Edge Sensor
Katrina E. Koehler, Michael A. Famiano, Chris J. Fontes +5
The neutrino mass can be extracted from a high statistics, high resolution calorimetric spectrum of electron capture in Ho. In order to better understand the shape of the…
