A tabletop x-ray tomography instrument for nanometer-scale imaging: demonstration of the 1,000-element transition-edge sensor subarray
Paul Szypryt, Nathan Nakamura, Daniel T. Becker +28
We report on the 1,000-element transition-edge sensor (TES) x-ray spectrometer implementation of the TOMographic Circuit Analysis Tool (TOMCAT). TOMCAT combines a high spatial reso…
Design of a 3000-pixel transition-edge sensor x-ray spectrometer for microcircuit tomography
Paul Szypryt, Douglas A. Bennett, William J. Boone +28
Feature sizes in integrated circuits have decreased substantially over time, and it has become increasingly difficult to three-dimensionally image these complex circuits after fabr…
Nanoscale Three-Dimensional Imaging of Integrated Circuits using a Scanning Electron Microscope and Transition-Edge Sensor Spectrometer
Nathan Nakamura, Paul Szypryt, Amber L. Dagel +30
X-ray nanotomography is a powerful tool for the characterization of nanoscale materials and structures, but is difficult to implement due to competing requirements on X-ray flux an…
Absolute Energy Measurements with Superconducting Transition-Edge Sensors for Muonic X-ray Spectroscopy at 44 keV
Daikang Yan, Joel C. Weber, Tejas Guruswamy +25
Superconducting transition-edge sensor (TES) microcalorimeters have great utility in x-ray applications owing to their high energy resolution, good collecting efficiency and the fe…
The 511-CAM Mission: A Pointed 511 keV Gamma-Ray Telescope with a Focal Plane Detector Made of Stacked Transition Edge Sensor Microcalorimeter Arrays
Farzane Shirazi, Md. Arman Hossen, Daniel Becker +18
The 511 keV gamma-ray emission from the galactic center region may fully or partially originate from the annihilation of positrons from dark matter particles with electrons from th…
Quantification of 242Pu with a Microcalorimeter Gamma Spectrometer
David J. Mercer, Ryan Winkler, Katrina E. Koehler +18
We report measurements of the 103-keV and 159-keV gamma ray signatures of 242Pu using microcalorimetry. This is the first observation of these gamma rays in a non-destructive measu…
