(author), Ravensberg, K. (author), Visser, S. (author), Nieuwenhuizen, A. C.T. (author), Gao, J.R. (author), den Herder, J. W. (author)Superconducting transition-edge sensors (TESs) are highly sensitive detectors. Based on the outstanding performance on spectral resolution, the X-ray integral field unit (X-IFU) instrument on-board athena will be equipped with a large array of TES-based microcalorimeters. For optimal performance in terms of the energy resolution, it is...journal article 2020

Development of a Ti/Au TES Microcalorimeter Array as a Backup Sensor for the Athena/X-IFU InstrumentNagayoshi, K. (author), Ridder, M. L. (author), Bruijn, M. P. (author), Gottardi, L. (author), Taralli, E. (author), Khosropanah, P. (author), Akamatsu, H. (author), Visser, S. (author), Gao, J.R. (author)We are developing a transition edge sensor (TES) microcalorimeter array based on a Ti/Au superconducting bilayer, as a backup option for the X-IFU instrument on the Athena X-ray observatory. The array is read out by a frequency-division multiplexing readout system using a 1–5 MHz frequency band. Extensive research collaborations between NASA...journal article 2019
