The traditional method of applying a digital optimal filter to measure X-ray pulses from transition-edge sensor (TES) devices does not achieve the best energy resolution when the signals have a highly non-linear response to energy, or the noise is no

The ideal X-ray camera for astrophysics would have more than a million pixels and provide an energy resolution of better than 1 eV FWHM for energies up to 10 keV. We have microfabricated and characterized thin-film magnetic penetration thermometers (

The measurement of calorimetric spectra following atomic weak decays, beta (b) and electron capture (EC), of nuclides having a very low Q-value, can provide an impressively high sensitivity to a non-vanishing neutrino mass. The achievable sensitivity

We are developing kilo-pixel arrays of TES microcalorimeters to enable high-resolution X-ray imaging spectrometers for future X-ray observatories and laboratory astrophysics experiments. Our current array design was targeted as a prototype for the X-

A still puzzling problem in the development of low temperature micro-calorimeters for the measurement of the 187rhenium β-spectrum is the understanding of the thermalization of energetic electrons in the superconducting rhenium absorber. We studied

In the last years the mixing of the three neutrino flavor eigenstates through a unitary matrix has been experimentally proved. Presently one of the greatest challenges in neutrino physics is to establish the absolute value of the masses of the three

Understanding the physical properties of the superconducting-to-normal transition is fundamental for optimizing the design and performance of transition-edge sensors (TESs). Recent critical current measurements of Mol Au bilayer test structures show

Magnetically coupled calorimeters (MCC) have extremely high potential for X-ray applications. Although very high energy-resolution has been demonstrated, until now there has been no multiplexed read-out of MCCs. We report on the first realization of
