“…This should be achieved by thermal filters in the aperture [163] and Au shielding in the proximity of the array. On top of that, the energy resolution of the detectors can be affected by thermal bath fluctuations from the energy deposited on the substrate by cosmic rays from astrophysical sources [164,165] and by micro-vibrations induced by the mechanical coolers [162,166]. A proper coating and thermalization of the TES array wafer can minimize the impact of the cosmic ray [167], while a sophisticated Kevlar-based suspension system is in development to provide robustness and stiffness to survive the launch and sufficient thermal and mechanical decoupling from the different cryostat stages [162].…”

The state-of-the-art technology of X-ray microcalorimeters based on superconducting transition-edge sensors (TESs), for applications in astrophysics and particle physics, is reviewed. We will show the advance in understanding the detector physics and describe the recent breakthroughs in the TES design that are opening the way towards the fabrication and the read-out of very large arrays of pixels with unprecedented energy resolution. The most challenging low temperature instruments for space- and ground-base experiments will be described.

“…We are using two stage VTT SQUIDs amp consisting of 6 array front end and 184×4 array amplification SQUIDs. The mechanical vibrations are damped by Kevlar wires 10 . To increase the bandwidth of the FDM, we compensate for the delay between the room temperature and 50 mK by using BaseBand Feed Back (BBFB) 11 .…”

Frequency domain multiplexing (FDM) is the baseline readout system for the Xray Integral Field Unit (X-IFU) on board the Athena mission. Under the FDM scheme, TESs are coupled to a passive LC filter and biased with alternating current (AC bias) at MHz frequencies. Using high-quality factor LC filters and room temperature electronics developed at SRON and low-noise two-stage SQUID amplifiers provided by VTT, we have recently demonstrated good performance with the FDM readout of Mo/Au TES calorimeters with Au/Bi absorbers. We have achieved a performance requested for the demonstration model (DM) with the single pixel AC bias (∆ E =1.8 eV) and 9 pixel multiplexing (∆ E =2.6 eV) modes. We have also demonstrated 14-pixel multiplexing with an average energy resolution of 3.3 eV, which is limited by non-fundamental issues related to FDM readout in our lab setup.

A prototype version of the Q & U Bolometric Interferometer for Cosmology (QUBIC) underwent a campaign of testing in the laboratory at Astroparticle Physics and Cosmology in Paris. The detection chain is currently made of 256 NbSi Transition Edge Sensors cooled to 320 mK. The readout system is a 128:1 Time Domain Multiplexing scheme based on 128 SQUIDs cooled at 1K that are controlled and amplified by an SiGe Application Specific Integrated Circuit at 40 K. We report the performance of this readout chain and the characterization of the TESs. The readout system has been functionally tested and characterized in the lab and in QUBIC. The Low Noise Amplifier demonstrated a white noise level of 0.3 nV/sqrt(Hz). Characterizations of the QUBIC detectors and readout electronics includes the measurement of I-V curves, time constant and the Noise Equivalent Power. The QUBIC TES bolometer array has approximately 80% detectors within operational parameters. While still limited by micro-phonics from the pulse tubes and noise aliasing from readout system, the Noise Equivalent Power is about 2 × 10 −16 W/ √ Hz, enough for the demonstration of bolometric interferometry. 18 4.8 Noise characterizations 21 4.8.1 Noise in normal and superconducting states 23 4.8.2 Noise in the transition 23 5 Conclusion 29
