“…For these reasons, the temperature of the HWP should be kept lower than 10-20 K, depending on the frequency of operation of the detectors. Similar arguments with relaxed requirements are applicable to balloon-borne (such as LSPE-SWIPE 13 ) and ground-based (such as QUBIC 14 ) experiments. Superconducting magnetic bearings provide a nearly frictionless, fast rotation of the HWP, perfectly compatible with the cryogenic implementation of the Stokes polarimeter.…”

QUBIC: Using NbSi TESs with a Bolometric Interferometer to Characterize the Polarization of the CMB

QUBIC (Q & U Bolometric Interferometer for Cosmology) is an international ground-based experiment dedicated in the measurement of the polarized fluctuations of the Cosmic Microwave Background (CMB). It is based on bolometric interferometry, an original detection technique which combine the immunity to systematic effects of an interferometer with the sensitivity of low temperature incoherent detectors. QUBIC will be deployed in Argentina, at the Alto Chorrillos mountain site near San Antonio de los Cobres, in the Salta province.The QUBIC detection chain consists in 2048 NbSi Transition Edge Sensors (TESs) cooled to 350mK.The voltage-biased TESs are read out with Time Domain Multiplexing based on Superconducting QUantum Interference Devices (SQUIDs) at 1 K and a novel SiGe Application-Specific Integrated Circuit (ASIC) at 60 K allowing to reach an unprecedented multiplexing (MUX) factor equal to 128.The QUBIC experiment is currently being characterized in the lab with a reduced number of detectors before upgrading to the full instrument. I will present the last results of this characterization phase with a focus on the detectors and readout system.

“…A clear example of this approach was the CORE satellite [3][4][5][6][7][8][9][10][11][12], proposed to but not funded by the European Space Agency, which should have had about 2000 detectors in 19 bands ranging from 60 to 600 GHz. In the past years, several experiments, both ground-based and balloonborne as well as satellites, have been proposed and funded with the goal to measure the primordial B-modes: the ground-based BICEP 3 [13] and Keck array [14], POLARBEAR-2 [15,16], QUBIC [17][18][19], Simons Observatory [20,21] and STRIP/LSPE [22][23][24]; the balloon-borne EBEX [25], SPIDER [26][27][28] and SWIPE/LSPE [23,24,29,30]; and the LiteBIRD satellite [31][32][33].…”

We have developed two arrays of lumped element kinetic inductance detectors working in the D-band, and optimised for the low radiative background conditions of a satellite mission aiming at precision measurements of the Cosmic Microwave Background (CMB). The first detector array is sensitive to the total power of the incoming radiation to which is coupled via single-mode waveguides and corrugated feed-horns, while the second is sensitive to the polarisation of the radiation thanks to orthomode transducers.Here, we focus on the total power detector array, which is suitable, for instance, for precision measurements of unpolarised spectral distortions of the CMB, where detecting both polarisations provides a sensitivity advantage. We describe the optimisation of the array design, fabrication and packaging, the dark and optical characterisation, and the performance of the black-body calibrator used for the optical tests. We show that almost all the detectors of the array are photon-noise limited under the radiative background of a 3.6 K black-body. This result, combined with the weak sensitivity to cosmic rays hits demonstrated with the OLIMPO flight, validates the idea of using lumped elements kinetic inductance detectors for precision, space-based CMB missions.
