Primary activity measurement of an Am-241 solution using microgram inkjet gravimetry and decay energy spectrometry

July 7, 2025

Author(s)

Ryan Fitzgerald, Bradley Alpert, Denis Bergeron, Max Carlson, Richard Essex, Kelsey Morgan, Shinichiro N. Muramoto, Svetlana Nour, Galen O'Neil, Daniel Schmidt, Gordon Shaw, Daniel Swetz, R Verkouteren

We demonstrate a method for radionuclide assay that is spectroscopic with 100 % counting efficiency for alpha decay. Advancing both cryogenic decay energy spectrometry (DES) and drop-on-demand inkjet metrology, a solution of Am-241 was assayed for massic

Characterization of Transition Edge Sensors for Decay Energy Spectrometry

May 16, 2024

Author(s)

Max Carlson, Ryan P. Fitzgerald, Galen O'Neil, Dan Schmidt

By using a superconducting Transition Edge Sensor (TES) to measure the thermal energy of individual decay events with high energy resolution (goal of 1 keV at 5 MeV), Decay Energy Spectrometry (DES) provides a unique fingerprint to identify each
