We present the design, optimization and laboratory characterization of an array of Lumped Element Kinetic Inductance Detectors sensitive in a frequency band centered at 350 GHz. The array consists of 313 feed-horn coupled pixels with resonant frequencies spread over 250 MHz. We present measured yield, quality factor, responsivity, quasiparticle lifetime, noise equivalent power and optical...
The LiteBIRD mission, to be launched in 2032, will map the polarization of the Cosmic Microwave Background (CMB) with unprecedented resolution, to search for the tiny imprints of cosmological inflation. Its sensitivity corresponds to exploring energy scales up to 10^{16} GeV, linking the physics of inflation with that of Grand Unification of elementary forces.
To accomplish this task,...
Cryogenic microwave technology is a rapidly growing field of business, driven by the boom of Quantum Computing (QC) and other Quantum Technologies (QT), but also with wide applications in reading out cryogenic particle detectors. Superconducting parametric amplifiers play a relevant role in reading out both superconducting qubits and low temperature particle detectors. These devices offer the...
High-frequency gravitational wave (GW) detection based on a cryogenic bulk acoustic wave (BAW) cavity coupled to a superconducting quantum interference device (SQUID) has been under investigation at the University of Western Australia for several years. A recent paper reported the observation of rare events of uncertain origin using the first antenna of this type. In this report, we describe...
We present BULLKID, a project aiming to deliver a scalable cryogenic detector for coherent neutrino nucleus scattering and low-mass Dark Matter direct detection.
The device consists of an array of silicon targets sensed by multiplexed Kinetic Inductance Detectors (KIDs).
The prototype we present is made of 64 cubic voxels of 5.4 × 5.4 × 5 mm3 each carved out of a 5 mm thick 3” silicon...
The EPR Experiment aims to demonstrate alternative Frequency-Dependent Squeezing (FDS) for reducing broadband quantum noise in gravitational wave detectors. We designed two reflective mode-matching telescopes (MMT) for an Einstein-Podolsky-Rosen (EPR) squeezing experiment. It can provide high mode matching for EPR entangled squeezed light. To ensure precise alignment and reproducibility of the...
The Quantum Technologies for Neutrino Mass (QTNM) is a UK-based neutrino mass measurement experiment which aims to leverage advances in quantum technology to develop a new experimental apparatus to determine the absolute neutrino mass.
The neutrino is the most abundant massive particle in the universe, and yet we do not know what its mass is. Measuring it — the last unknown mass(es) in the...
Semiconductor nanocrystals (“quantum dots”) are light emitters with high quantum yield that are relatively easy to manufacture. There is therefore much interest in their possible application for the development of high-performance scintillators for use in high-energy physics. Nanocomposite scintillators can be obtained by casting nanocrystals into a transparent polymer matrix, to obtain...
The dawn of Gravitational-wave (GW) astronomy is dated September 14th, 2015, with the first direct detection of a GW signal through long-baseline Michelson-Fabry-Perot interferometers. Among the noise sources affecting these GW detectors, Quantum Noise is present in their whole bandwidth (10 Hz – 10 kHz).
In the current scientific run named O4, the GW advanced detectors LIGO and Virgo attain...
Current advancements in low-energy rare-event searches rely on cryogenic calorimeters, commonly used for the direct detection of dark matter or neutrinos. These detectors provide a low-noise environment but face challenges in characterizing responses within the region of interest (ROI). Developed for probing energies from O(10eV) to O(1keV), these detectors encounter issues when calibrating...
The electron electric dipole moment (eEDM) is a sensitive probe to investigate new physics beyond the Standard Model. We propose a novel experimental method to measure the eEDM using polar molecules (BaF) embedded in a cryogenic matrix of parahydrogen. This approach could improve the current eEDM limits, offering valuable insights into CP violation sources and the origin of matter-antimatter...
The HOLMES experiment seeks to directly assess the neutrino mass by investigating the electron capture decay spectrum of $^{163}$Ho. This involves developing arrays of micro-calorimeters based on Transition Edge Sensor (TES) technology, each implanted with approximately $10^2$ Bq/detector of $^{163}$Ho atoms.
To incorporate the $^{163}$Ho source into the detector while simultaneously...
Superconducting Transition-Edge Sensors (TESs) are promising detectors for experiments searching for rare signal events thanks to their high efficiency and extremely low dark count rates. To further enhance their sensitivity, it is essential to investigate the origins of these dark counts, a topic that has not been extensively studied. We found that the primary sources of dark counts in...
We present an extension on vibration analysis of the 50 mK Cryogenic focal plane Anti-Coincidence (CryoAC) detector designed for the X-IFU Athena X-ray observatory. The detector is composed of a silicon suspended absorber coupled with a few Ir/Au Transition Edge Sensors (TES) linked via silicon bridges to a gold-plated silicon frame (rim). The detector was fabricated through Deep Reactive Ion...
