FOSSIL: Thermo-mechanical architecture

Valentin Sauvage, Clémence De Jabrun, Sylvain Martin, Bruno Maffei et autres

FOSSIL (FTS fOr CMB Spectral diStortIon expLoration) is a proposed ESA M8 mission tailored to measure the spectral distortions of the Cosmic Microwave Background (CMB) with a sensitivity three orders of magnitude beyond the COBE/FIRAS legacy measurement. Achieving this sensitivity demands an …

A path towards CMB spectral distortion measurements

Bruno Maffei, Nabila Aghanim, Valentin Sauvage, Morgane Loquet Le Gall et autres

The only detailed measurement of the cosmic microwave background (CMB) spectrum, by COBE-FIRAS in the early 90s, showed that it is close to perfect blackbody emission. However, theory predicts that small deviations, referred to as CMB spectral distortions, are expected, but, due …

Radiation qualification of lens-absorber and antenna-coupled KIDs for the PRIMA mission

Giulia Conenna, Stephen Yates, Kenichi Karatsu, A Besnard et autres

Despite significant progress in far-infrared detector technology, demonstrating radiation hardness remains a critical step for space qualification. This is particularly relevant for the PRIMA mission, which require detectors capable of operating reliably over a decade in the L2 environment. PRIMAger includes two …

Characterization of high-sensitivity cryogenic detectors' susceptibility to cosmic rays

A Besnard, Valentin Sauvage, Giulia Conenna, Kenichi Karatsu et autres

Future space missions and balloon-borne experiments are always in need of larger number of highly sensitive cryogenic detectors. Upcoming technologies currently under development will undoubtedly be affected by cosmic rays, resulting in heat dissipation spreading through the detector arrays and creating spurious …

Prototype design of an internal blackbody reference for BISOU

Thomas J. L. J. Gascard, Valentin Sauvage, Rustam Balafendiev, Morgane Loquet Le Gall et autres

The CMB spectral distortions, minute deviations from a pure blackbody spectrum, encode crucial information about cosmic processes from inflation to galaxy formation. The FOSSIL space mission, currently in the second phase of ESA M8 selection, aligning with some of the goals set …

TES Proton Irradiation Result Analysis for Future Space Applications

A Besnard, V. Sauvage, S. L. Stever, B. Maffei et autres

As observed on the signal of the Planck-HFI highly sensitive bolometers, the effect of cosmic rays on detectors is a major concern for future similar space missions. Their instruments will have a larger detection surface, increased sensitivity, and more stringent requirements on …

FOSSIL's preliminary thermal architecture

V. Sauvage, Clémence De Jabrun, A Besnard, Bruno Borgo et autres

FOSSIL (FTS fOr CMB Spectral diStortIon expLoration) is a proposed ESA M8 mission tailored to measure the spectral distortions monopole of the Cosmic Microwave Background (CMB) with a sensitivity three orders of magnitude beyond the COBE/FIRAS legacy measurement. Achieving this sensitivity demands …

Successful irradiation campaign on PRIMA/PRIMAger KIDs detectors with DRACuLA

V. Sauvage, A Besnard, Giulia Conenna, Kenichi Karatsu et autres

DRACuLA (Detector irRAdiation Cryogenic faciLity for Astrophysics) is a mobile dilution refrigerator platform developed at the Institut d'Astrophysique Spatiale (IAS) to expose sub-Kelvin detectors to particle beams at their nominal operating temperature, in the range 50-300 mK. We report on its design, …

Study of cosmic ray impacts on cryogenic high sensitivity detectors

A Besnard, Valentin Sauvage, Bruno Maffei

After the Planck mission's launch in 2009, bolometers of its High Frequency Instrument (HFI) were considerably affected by cosmic rays, which necessitated several years of post-treatment to clean the data. To study the susceptibility of high sensitivity cryogenic detectors to particle impacts, …

Mitigating half-wave plate systematics at the map-making level: calibration requirements for LiteBIRD

N. Raffuzzi, A. Carones, M. Monelli, S. Giardiello et autres

Although half-wave plates (HWPs) are becoming a popular choice of polarization modulators for cosmic microwave background (CMB) experiments, their non-idealities can introduce systematic effects that should be carefully characterized and mitigated. One possible mitigation strategy is to incorporate information about the non-idealities …
