“…If we assume that α particles were irradiated at the position of the resonator which gave a higher pulse height, we may be able to estimate the propagation velocity of athermal phonons. From the distance between the adjacent resonators of 1.6 mm, we make a rough estimation of the velocity to be 1.1-1.3 km/s, which is comparable to the results obtained by Swenson et al [5].…”

We present a status of the development of microwave kinetic inductance detectors (MKIDs) for a detection of athermal phonons in a substrate. The energy deposited in the substrate is converted to athermal phonons. Athermal phonons arriving at the surface can break Cooper pairs in the MKIDs which are formed as a thin superconducting metal layer in the substrate surface. By counting the number of Cooper pairs broken and measuring the phonon arrival times, we can measure the amount of deposited energy and its position. MKIDs are suitable for the frequency-domain multiplexing readout, which enables us to readout hundreds of pixels simultaneously and, hence, to detect athermal phonons with a large detection efficiency. We fabricated MKIDs with a combination of aluminum and niobium on a silicon substrate, and then irradiated it with α particles from an 241 Am source. We detected phonons and made a rough estimation of the phonon propagation velocity of 1.1-1.3 km/s. We found that a thin insulator layer can block the phonon propagation from the substrate to the thin metal layer.

“…Unlike traditional bolometric instruments, NIKA uses KIDs. The KIDs are superconducting resonators whose resonance frequency (∼1−2.5 GHz) changes linearly with the absorbed optical power (see for example Swenson et al 2010). Each resonator can be modeled by a complex transfer function in frequency with a real part I (in-phase) and imaginary part Q (quadrature; Grabovskij et al 2008).…”

Context. Clusters of galaxies provide valuable information on the evolution of the Universe and large scale structures. Recent cluster observations via the thermal Sunyaev-Zel'dovich (tSZ) effect have proven to be a powerful tool to detect and study them. In this context, high resolution tSZ observations (∼tens of arcsec) are of particular interest to probe intermediate and high redshift clusters. Aims. Observations of the tSZ effect will be carried out with the millimeter dual-band NIKA2 camera, based on kinetic inductance detectors (KIDs) to be installed at the IRAM 30-m telescope in 2015. To demonstrate the potential of such an instrument, we present tSZ observations with the NIKA camera prototype, consisting of two arrays of 132 and 224 detectors that observe at 140 and 240 GHz with a 18.5 and 12.5 arcsec angular resolution, respectively. Methods. The cluster RX J1347.5-1145 was observed simultaneously at 140 and 240 GHz. We used a spectral decorrelation technique to remove the atmospheric noise and obtain a map of the cluster at 140 GHz. The efficiency of this procedure has been characterized through realistic simulations of the observations. Results. The observed 140 GHz map presents a decrement at the cluster position consistent with the tSZ nature of the signal. We used this map to study the pressure distribution of the cluster by fitting a gNFW model to the data. Subtracting this model from the map, we confirm that RX J1347.5-1145 is an ongoing merger, which confirms and complements previous tSZ and X-ray observations. Conclusions. For the first time, we demonstrate the tSZ capability of KID based instruments. The NIKA2 camera with ∼5000 detectors and a 6.5 arcmin field of view will be well-suited for in-depth studies of the intra cluster medium in intermediate to high redshifts, which enables the characterization of recently detected clusters by the Planck satellite.

“…Obtaining a similar surface with KIDs would require hundreds of pixels for each LD, which is not a realistic option for experiments with ∼1000 detectors. This problem can be overcome following the phonon-mediated approach developed for Neutron Tansmutation Doped Ge thermistors 10 and for Transition Edge Sensors 11 , and recently proposed also for KIDs 12,13 .…”

The development of sensitive cryogenic light detectors is of primary interest for bolometric experiments searching for rare events like dark matter interactions or neutrino-less double beta decay. Thanks to their good energy resolution and the natural multiplexed read-out, Kinetic Inductance Detectors (KIDs) are particularly suitable for this purpose. To efficiently couple KIDs-based light detectors to the large crystals used by the most advanced bolometric detectors, active surfaces of several cm 2 are needed. For this reason, we are developing phonon-mediated detectors. In this paper we present the results obtained with a prototype consisting of four 40 nm thick aluminum resonators patterned on a 2×2 cm 2 silicon chip, and calibrated with optical pulses and X-rays. The detector features a noise resolution σ E = 154 ± 7 eV and an (18±2) % efficiency.
