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…
A Transition-edge Sensor-based X-ray Spectrometer for the Study of Highly Charged Ions at the National Institute of Standards and Technology Electron Beam Ion Trap
P. Szypryt, G. C. O'Neil, E. Takacs +15
We report on the design, commissioning, and initial measurements of a Transition-edge Sensor (TES) x-ray spectrometer for the Electron Beam Ion Trap (EBIT) at the National Institut…
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…
