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 Atacama Cosmology Telescope: A Measurement of the Cosmic Microwave Background Power Spectra at 98 and 150 GHz
Steve K. Choi, Matthew Hasselfield, Shuay-Pwu Patty Ho +136
We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg of the 2013-2016 survey, which cove…
The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters
Simone Aiola, Erminia Calabrese, Loïc Maurin +138
We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013…
A Highly Linear Calibration Metric for TES X-ray Microcalorimeters
C. G. Pappas, J. W. Fowler, D. A. Bennett +6
Transition-edge sensor X-ray microcalorimeters are usually calibrated empirically, as the most widely-used calibration metric, optimal filtered pulse height (OFPH), in general has…
Approaches to the Optimal Nonlinear Analysis of Microcalorimeter Pulses
J. W. Fowler, C. G. Pappas, B. K. Alpert +4
We consider how to analyze microcalorimeter pulses for quantities that are nonlinear in the data, while preserving the signal-to-noise advantages of lin- ear optimal filtering. We…
The Atacama Cosmology Telescope: Two-Season ACTPol Spectra and Parameters
Thibaut Louis, Emily Grace, Matthew Hasselfield +80
We present the temperature and polarization angular power spectra measured by the Atacama Cosmology Telescope Polarimeter (ACTPol). We analyze night-time data collected during 2013…
The Atacama Cosmology Telescope: The polarization-sensitive ACTPol instrument
R. J. Thornton, P. A. R. Ade, S. Aiola +53
The Atacama Cosmology Telescope (ACT) is designed to make high angular resolution measurements of anisotropies in the Cosmic Microwave Background (CMB) at millimeter wavelengths. W…
The Atacama Cosmology Telescope: Lensing of CMB Temperature and Polarization Derived from Cosmic Infrared Background Cross-Correlation
Alexander van Engelen, Blake D. Sherwin, Neelima Sehgal +47
We present a measurement of the gravitational lensing of the Cosmic Microwave Background (CMB) temperature and polarization fields obtained by cross-correlating the reconstructed c…
The Atacama Cosmology Telescope: CMB Polarization at
Sigurd Naess, Matthew Hasselfield, Jeff McMahon +75
We report on measurements of the cosmic microwave background (CMB) and celestial polarization at 146 GHz made with the Atacama Cosmology Telescope Polarimeter (ACTPol) in its first…
Observation of reentrant quantum Hall states in the lowest Landau level
