We are developing high performance X-ray detectors based on superconducting transition-
edge sensors (TES) for application in materials analysis and astronomy. Using our recently …

In many superconducting transition-edge sensor (TES) microcalorimeters, the measured
electrical noise exceeds theoretical estimates based on a thermal model of a single body …

The current noise at the output of a microcalorimeter with a voltage biased superconducting
transition edge thermometer is studied in detail. In addition to the two well-known noise …

The measured noise in Mo/Au transition-edge sensor (TES) microcalorimeters produced at
NASA has recently been shown to be well described by a two-body electro-thermal model …

During 1999 and 2000 three X-ray astronomy satellite missions will be launched. One of
those, the Japanese ASTRO-E, carries the first cryogenic X-ray imaging spectrometer with …

Superconducting transition edge sensor (TES) bolometers require superconducting films to
have controllable transition temperatures T c in different practical applications. The value of …

We are developing arrays of high-performance detectors based on superconducting
transition-edge sensors (TES) for application in x-ray materials analysis as well as x-ray and …

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 …

The extent and composition of the soft Diffuse X-ray Background (DXRB) has been the
subject of debate since its discovery in the 1960s. Initially assumed to be extragalactic, it …

The temperature dependence of the electrical resistance (RT) and the current-voltage (IV)
characteristics has been measured and analyzed in a 40 nm thick Ti thin film, which is used …
