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
