We are developing arrays of position-sensitive transition-edge sensor (PoST) X-ray
detectors for future astronomy missions such as NASA's Constellation-X. The PoST consists …

Following our development of a superconducting transition-edge-sensor (TES)
microcalorimeter design that en-ables reproducible, high performance (routinely better than …

We report on the development of multi-absorber transition-edge sensors (TESs), referred to
as 'hydras'. A hydra consists of multiple X-ray absorbers each with a different thermal …

Uniform large transition-edge sensor (TES) arrays are fundamental for the next generation of
x-ray space observatories. These arrays are required to achieve an energy resolution ΔE< 3 …

Individual x-ray calorimeters based on superconducting transition-edge sensors (TES) have
already demonstrated the spectral resolution, speed, and quantum efficiency needed for …

We report on the development of an imaging detector with high energy resolution for the X-
ray Evolving Universe Spectroscopy Mission (XEUS). The type of detector we are studying is …

We present experimental results and designs of large‐absorber transition‐edge‐sensor
(TES) X‐ray microcalorimeters. Much of our effort has focused on developing close‐packed …

We have been developing x-ray microcalorimeters for the Constellation-X mission. Devices

NASA's Constellation-X (Con-X) mission is a driver for advancing low-temperature detector
technologies, requiring 1000-pixel two-dimensional arrays with> 95% filling fraction and …

We are developing arrays of X-ray microcalorimeters on a 50-µm pitch that utilize transition-
edge sensors as the sensor to measure the temperature rise when X-rays are absorbed. An …
