Towards Precision Spectroscopy of Antiprotonic Atoms for Probing Strong-field QED
Gonçalo Baptista, Shikha Rathi, Michael Roosa +26
PAX (antiProtonic Atom X-ray spectroscopy) is a new experiment with the aim to test strong-field quantum electrodynamics (QED) effects by performing high-precision x-ray spectrosco…
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…
Direct Imaging of Transition-Edge Sensors with Scanning SQUID Microscopy
Samantha Walker, Austin Kaczmarek, Jason Austermann +10
Significant advancements have been made in understanding the physics of transition-edge sensors (TESs) over the past decade. However, key questions remain, particularly a detailed…
Few-electron highly charged muonic Ar atoms verified by electronic x rays
T. Okumura, T. Azuma, D. A. Bennett +40
Electronic x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra p…
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…
