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…
Energy calibration of nonlinear microcalorimeters with uncertainty estimates from Gaussian process regression
J. W. Fowler, B. K. Alpert, G. C. O'Neil +2
The nonlinear energy response of cryogenic microcalorimeters is usually corrected through an empirical calibration. X-ray or gamma-ray emission lines of known shape and energy anch…
Progress in the development of TES microcalorimeter detectors suitable for neutrino mass measurement
A. Giachero, B. Alpert, D. T. Becker +19
The HOLMES experiment will perform a precise calorimetric measurement of the end point of the Electron Capture (EC) decay spectrum of 163Ho in order to extract information on neutr…
Absolute energies and emission line shapes of the L x-ray transitions of lanthanide metals
Joseph W. Fowler, Galen C. O'Neil, Bradley K. Alpert +11
We use an array of transition-edge sensors, cryogenic microcalorimeters with 4 eV energy resolution, to measure L x-ray emission-line profiles of four elements of the lanthanide se…
Status of the HOLMES Experiment to Directly Measure the Neutrino Mass
A. Nucciotti, B. Alpert, M. Balata +35
The assessment of neutrino absolute mass scale is still a crucial challenge in today particle physics and cosmology. Beta or electron capture spectrum end-point study is currently…
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 Practice of Pulse Processing
J. W. Fowler, B. K. Alpert, W. B. Doriese +4
The analysis of data from x-ray microcalorimeters requires great care; their excellent intrinsic energy resolution cannot usually be achieved in practice without a statistically ne…
HOLMES - The Electron Capture Decay of 163Ho to Measure the Electron Neutrino Mass with sub-eV sensitivity
B. Alpert, M. Balata, D. Bennett +35
The European Research Council has recently funded HOLMES, a new experiment to directly measure the neutrino mass. HOLMES will perform a calorimetric measurement of the energy relea…
