We are developing the Cryogenic AntiCoincidence detector (CryoAC) of ATHENA X-IFU spectrometer. It is a TES-based particle aimed to reduce background instrument. Here, we present result obtained with last CryoAC single-pixel prototype. based on 1 cm2 silicon absorber sensed by single 2mm x 1mm Ir/Au TES, featuring an on-chip heater for calibration and diagnostic purposes. have illuminated sample 55Fe (6 keV line) 241Am (60 radioactive sources, thus studying response accuracy at low energy....
The Cryogenic AntiCoincidence Detector (CryoAC) is a key element of the X-ray Integral Field Unit (X-IFU) on board future ATHENA observatory. It TES-based detector designed to reduce particle background instrument, thereby increasing its sensitivity. design driven by an end-to-end simulator which includes electro-thermal modelling and dynamics readout chain. Here, we present measurements carried out last CryoAC single pixel prototype, namely DM127, in order evaluate critical thermal...

THESEUS (Transient High Energy Sky and Early Universe Surveyor) is one of the three missions selected by ESA as fifth medium class mission (M5) candidates in its Cosmic Vision science program, currently under assessment a phase A study with planned launch date 2032. designed to carry on-board two wide deep sky monitoring instruments for X/gamma-ray transients detection: wide-field soft X-ray monitor imaging capability (Soft Imager, SXI, 0.3 – 5 keV), hard X-ray, partially-imaging...
Athena (advanced telescope for high-energy astrophysics) is an ESA large-class mission, at present under a re-definition “design-to-cost” phase, planned prospective launch L1 orbit in the second half of 2030s. It will be observatory alternatively focusing on two complementary instruments: X-IFU (X-ray Integral Field Unit), TES (TransitionEdge Sensor)-based kilo-pixel array which able to perform simultaneous high-grade energy spectroscopy (~3 eV@7 keV) and imaging over 4′ FoV (field view),...
The Italian Space Agency plays a key role in the fulfillment of space missions, contributing to scientific, technological and economic progress Italy. agency accomplishes experiments by collaborating with scientific industrial entities, supporting them realization new projects able achieve, over last two decades, unprecedented results obtention fundamental information on birth evolution universe. paper describes selection X-ray technologies developed synergy between its principal...
Abstract We have developed two arrays of lumped element kinetic inductance detectors working in the D-band, and optimised for low radiative background conditions a satellite mission aiming at precision measurements Cosmic Microwave Background (CMB) radiation. The first detector array is sensitive to total power incoming radiation which coupled via single-mode waveguides corrugated feed-horns, while second polarisation thanks orthomode transducers. Here, we focus on array, suitable, instance,...
In this paper we discuss the latest developments of STRIP instrument "Large Scale Polarization Explorer" (LSPE) experiment. LSPE is a novel project that combines ground-based (STRIP) and balloon-borne (SWIPE) polarization measurements microwave sky on large angular scales to attempt detection "B-modes" Cosmic Microwave Background polarization. will observe approximately 25% Northern from "Observatorio del Teide" in Tenerife, using an array forty-nine coherent polarimeters at 43 GHz, coupled...

In the recent years, an increasing interest towards enhanced and more frequent operations at high altitudes has been demonstrated both by aerospace industry academics. particular, many institutions companies are developing so-called HAPS (High Altitude Platform Stations, [1] - [3] ), altitude balloons provided with low-thrust propulsion systems able to maintain their position over a target. These vehicles power generation perform long-term missions of weeks or even months. On other hand,...
Our team is developing the Cryogenic Anticoincidence Detector (CryoAC) of ATHENA X-ray Integral Field Unit (X-IFU). It a 4-pixels TES-based detector, which will be placed less than 1 mm below main TES array detector.
