“…However, other transition temperatures can be selected depending on applications. Various types of films have been proposed and successfully used for almost any photon wavelength to achieve the targeted transition temperatures; a single layer of tungsten [86,87], alloys such as Al-Mn [88], and proximity-coupled bilayers (or multilayers) of Ti/Au [89], Mo/Au [90][91][92][93], Mo/Cu [94], Ir/Au [95], and Al/Ti [96,97]. The geometric size of the superconducting slices is normally tens of microns or larger so wet etch, dry etch, or lift-off processes can be adopted in combination with a standard UV photolithography.…”

The state-of-the-art technology of X-ray microcalorimeters based on superconducting transition-edge sensors (TESs), for applications in astrophysics and particle physics, is reviewed. We will show the advance in understanding the detector physics and describe the recent breakthroughs in the TES design that are opening the way towards the fabrication and the read-out of very large arrays of pixels with unprecedented energy resolution. The most challenging low temperature instruments for space- and ground-base experiments will be described.

“…The baseline energy resolution (ie, the absolute sensitivity) of the BLD is given by the width of randomly acquired baselines (noise) after the application of OF. As is typical for this style of detectors, the energy resolution of monochromatic energy absorption events is much worse than the baseline resolution, irrespective of the type of sensor [13,12] The noise and signal power spectra of the BLD are presented in Fig. 3.…”

We have developed and tested a new way of coupling bolometric light detectors to scintillating crystal bolometers based upon simply resting the light detector on the crystal surface, held in position only by gravity. This straightforward mounting results in three important improvements: (1) it decreases the amount of non-active materials needed to assemble the detector, (2) it substantially increases the light collection efficiency by minimizing the light losses induced by the mounting structure, and (3) it enhances the thermal signal induced in the light detector thanks to the extremely weak thermal link to the thermal bath.We tested this new technique with a 16 cm 2 Ge light detector with thermistor readout sitting on the surface of a large TeO 2 bolometer. The light collection efficiency was increased by greater than 50% compared to previously tested alternative mountings. We obtained a baseline energy resolution on the light detector of 20 eV RMS that, together with increased light collection, enabled us to obtain the best α vs β/γ discrimination ever obtained with massive TeO 2 crystals. At the same time we achieved rise and decay times of 0.8 and 1.6 ms, respectively. This superb performance meets all of the requirements for the CUPID (CUORE Upgrade with Particle IDentification) experiment, which is a 1-ton scintillating bolometer follow up to CUORE. tons, producing heat (phonons) that is measured by a suitable thermometer. The main difference among the various Bolometric Light Detector (BLD) instruments currently in use is the choice of the thermometer element, e.g. Transition Edge Sensors (TES) [12], Neutron Transmutation Doped (NTD) thermistors [13] or Micro Magnetic Calorimeters (MMC) [14].The work presented here was performed within the CU-PID framework [15,16], the future follow up of CUORE [17] that represents the largest world-wide bolometric experiment to date. The aim was to develop NTD-based BLDs with improved performance in terms of sensitivity, time response and simplified packaging for large arrays. Using the tiny Cherenkov light emission of TeO 2 [18,19] to decrease by two order of magnitude the α-induced background, requires a BLD with a S/N ratio of the order of ∼5 [16]: this corresponds to a RMS baseline resolution of the BLD of the order of ∼20 eV being the Cherenkov light signal of the order of 100 eV. Actually one can work towards the optimization of the light collection [20] and/or towards the energy resolution of the BLD or -as we made in this work-both. Additionally, in case of 100 Mo-based compounds, beside the same need to suppress the surface α-induced background, a fast time response of the BLD (≤ 1 ms) is mandatory to suppress the background induced the pile-up of the 2ν DBD [21]: also in this case the S/N ratio will play an important

“…The Si substrate works as carrier, transporting the phonons produced in the Li 2 MoO 4 crystal by interacting particles to the KID deposited on it. This is the same technique that the CRESST experiment [25] successfully applied to transition edge sensors [26]. The layout of the experimental set up is showed in Fig.…”

Molybdenum based crystals such as Li 2 MoO 4 and CaMoO 4 are emerging as leading candidates for next generation experiments searching for neutrino-less double beta decay with cryogenic calorimeters (CUPID, AMoRE). The exquisite energy resolution and high radio-purity of these crystals come at the cost of a potentially detrimental background source: the two neutrinos double beta decay of 100 Mo. Indeed, the fast half-life of this decay mode, combined with the slow response of cryogenic calorimeters, would result in pileup events in the energy region of interest for neutrinoless double beta decay, reducing the experimental sensitivity. This background can be suppressed using fast and high sensitivity cryogenic light detectors, provided that the scintillation time constant itself does not limit the time resolution. We developed a new detection technique exploiting the high sensitivity, the fast time response and the multiplexing capability of Kinetic Inductance Detectors. We applied the proposed technique to a 2 × 2 × 2 cm 3 Li 2 MoO 4 crystal, which was chosen as baseline option for CUPID. We measured simultaneously both the phonon and scintillation signals with KIDs. We derived the scintillation time constant of this compound at millikelvin temperatures obtaining τ scint = 84.5 ± 4.5(syst) ± 1.0(stat) μs, constant between 10 and 190 mK.
