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 Microwave SQUID Multiplexer Optimized for Bolometric Applications
B. Dober, Z. Ahmed, K. Arnold +27
A microwave SQUID multiplexer (MUX) has been optimized for coupling to large arrays of superconducting transition-edge sensor (TES) bolometers. We present the scalable cryogenic…
Improved Plutonium and Americium Photon Branching Ratios from Microcalorimeter Gamma Spectroscopy
Michael D. Yoho, Katrina E. Koehler, Daniel T. Becker +15
Photon branching ratios are critical input data for activities such as nuclear materials protection and accounting because they allow material compositions to be extracted from mea…
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…
