Primary activity measurement of an Am-241 solution using microgram inkjet gravimetry and decay energy spectrometry
Ryan P. Fitzgerald, Bradley Alpert, Denis E. Bergeron +11
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 dr…
A Reassessment of Absolute Energies of the X-ray L Lines of Lanthanide Metals
J. W. Fowler, B. K. Alpert, D. A. Bennett +12
We introduce a new technique for determining x-ray fluorescence line energies and widths, and we present measurements made with this technique of 22 x-ray L lines from lanthanide-s…
When "Optimal Filtering" Isn't
J. W. Fowler, B. K. Alpert, W. B. Doriese +8
The so-called "optimal filter" analysis of a microcalorimeter's x-ray pulses is statistically optimal only if all pulses have the same shape, regardless of energy. The shapes of pu…
