We have developed a SQUID controller unit for TES sensors readout, designed to be used in a space mission. The unit is made of 8 boards and each board can condition four SQUID array amplifiers. The board design is inspired by a similar one developed for ground based experiments, but specific changes have been made to adopt COTS with space grade equivalents, to implement redundancy and...

To achieve the extreme sensitivities necessary to perform elusive particle searches like $\beta$-decay spectroscopy for neutrino mass measurement or dark matter detection, future experiments will employ large arrays of cryogenic detectors, such as metallic-magnetic calorimeters or transition-edge sensors (TES).
A TES is a thin film of superconducting material weakly coupled to a thermal...

Nowadays, many experiments with very high energy resolution detectors rely on the faithful detection of low power microwave signals at cryogenic temperatures. This is especially true also in the field of the superconducting quantum computation, where quantum-limited noise microwave amplification is paramount to infer the qubit state with high fidelity.
For these applications, the goals are...

The 50 mK cryogenic focal plane anti-coincidence detector of the Athena X-ray observatory (CryoAC) is a silicon suspended absorber sensed by a network of 400 Ir/Au Transition Edge Sensors (TES) and connected through silicon bridges to a surrounding silicon frame plated with gold (RIM). The device is shaped by Deep Reactive Ion Etching (DRIE) from a single silicon wafer of 500 um. There are two...

Future experiments pursuing scientific breakthroughs in the fields of astronomy, cosmology or astro-particle physics will take advantage of the extreme sensitivities of cryogenic detectors, such as transition-edge sensors (TES).
A TES is a thin film of superconducting material weakly coupled to a thermal bath typically at $T < 100$~mK, used as a radiation detector by exploiting its sharp...

The current technology of thermal detectors for rare events physics is based on large cryogenic calorimeters read with NTD thermistors. Measuring the total energy deposition via the heat release in the crystal lattice allows for optimal energy resolutions when the detectors are operated at 10mK. In case the crystals are made of a scintillating material, a double readout of heat and...

Coherent elastic neutrino nucleus scattering (CEvNS) is a well-predicted Standard Model process only recently observed for the first time. Its precise study could reveal non-standard neutrino properties and open a window to search for physics beyond the Standard Model.
NUCLEUS is a CEvNS experiment conceived for the detection of neutrinos from nuclear reactors with unprecedented precision...

Quantum sensing is a rapidly growing field of research which is already improving sensitivity in fundamental physics experiments. The ability to control quantum devices to measure physical quantities received a major boost from superconducting qubits and the improved capacity in engineering and fabricating this type of devices. Superconducting qubits have already been successfully applied in...

The electron electric dipole moment (e-EDM) is a model-independent probe of parity and time-reversal violation at energies beyond the ones that can be reached in particle colliders. The PHYDES project is an R&D experiment funded by CSN V of INFN aimed to test innovative approaches for e-EDM studies. In particular, the proposed idea is to use diatomic polar molecules, where e-EDM effects are...
