Voltage Fluctuations in ac Biased Superconducting Transition-Edge Sensors
L. Gottardi, M. de Wit, E. Taralli +2
We present a detailed analysis of the fundamental noise sources in superconducting transition-edge sensors (TESs), ac voltage biased at MHz frequencies and treated as superconducti…
Demonstration of MHz frequency domain multiplexing readout of 37 transition edge sensors for high-resolution x-ray imaging spectrometers
H. Akamatsu, D. Vaccaro, L. Gottardi +22
We report on the development and demonstration of a MHz frequency domain multiplexing (FDM) technology to read out arrays of cryogenic transition edge sensor (TES) X-ray microcalor…
Impact of the absorber coupling design for Transition Edge Sensor X-ray Calorimeters
M. de Wit, L. Gottardi, E. Taralli +10
Transition Edge Sensors (TESs) are the selected technology for future spaceborne X-ray observatories, such as Athena, Lynx, and HUBS. These missions demand thousands of pixels to b…
High Aspect Ratio Transition Edge Sensors for X-ray Spectrometry
M. de Wit, L. Gottardi, E. Taralli +11
We are developing large TES arrays in combination with FDM readout for the next generation of X-ray space observatories. For operation under AC-bias, the TESs have to be carefully…
A test platform for the detection and readout chain for the Athena X-IFU
Gabriele Betancourt-Martinez, François Pajot, Sophie Beaumont +26
We present a test platform for the Athena X-IFU detection chain, which will serve as the first demonstration of the representative end-to-end detection and readout chain for the X-…
TiAu TES 3232 pixel array: uniformity, thermal crosstalk and performance at different X-ray energies
E. Taralli, M. D'Andrea, L. Gottardi +10
Large format arrays of transition edge sensor (TES) are crucial for the next generation of X-ray space observatories. Such arrays are required to achieve an energy resolution of $\…
