(author)In this paper we present the results of our 176-pixel prototype of the FDM readout system for SAFARI, a TES-based focal-plane instrument for the far-IR SPICA mission. We have implemented the knowledge obtained from the detailed study on electrical crosstalk reported previously. The effect of carrier leakage is reduced by a factor two, mutual...conference paper 2016

Van der Kuur, J. (author), Beyer, J. (author), Bruijn, M. (author), Gao, J.R. (author)SAFARI is an imaging Fourier Transform Spectrometer for 35–200 ?m under development for flight on the Japanese IR-satellite SPICA (2018). The 3.25 m diameter actively cooled telescope (<6K) will provide a sky background limited signal, which implies that detectors will need to have an NEP of 3.5?10 ?19 W/Hz ? ? ? in order not to be limiting the...journal article 2012

Vaccaro, D. (author), Akamatsu, H. (author), Gottardi, L (author), Van Der Kuur, J. (author), Taralli, E. (author), de Wit, M. (author), Bruijn, MP (author), den Hartog, R (author), Gao, J.R. (author)We present a characterization of the sensitivity of TES X-ray micro-calorimeters to environmental conditions under frequency-domain multiplexing (FDM) readout. In the FDM scheme, each TES in a readout chain is in series with a LC band-pass filter and AC biased with an independent carrier at MHz range. Using TES arrays, cold readout circuitry and...journal article 2022
