On low-energy tail distortions in the detector responsefunction of x-ray microcalorimeter spectrometers
G. C. O'Neil, P. Szypryt, E. Takacs +12
We use narrow spectral lines from the x-ray spectra of various highlycharged ions to measure low-energy tail-like deviations from a Gaussian responsefunction in a microcalorimter x…
A robust principal component analysis for outlier identification in messy microcalorimeter data
J. W. Fowler, B. K. Alpert, Y. -I. Joe +3
A principal component analysis (PCA) of clean microcalorimeter pulse records can be a first step beyond statistically optimal linear filtering of pulses towards a fully non-linear…
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…
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…
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…
Microcalorimeter Spectroscopy at High Pulse Rates: a Multi-Pulse Fitting Technique
J. W. Fowler, B. K. Alpert, W. B. Doriese +6
Transition edge sensor microcalorimeters can measure x-ray and gamma-ray energies with very high energy resolution and high photon-collection efficiency. For this technology to rea…
