The Chinese-French mission SVOM due to be launched in 2023 is the next generation of missions fully dedicated to the survey of the transient sky thanks to an agile spacecraft embarking a multi-wavelength science payload associated with a network of ground robotic nIR/optical telescopes. The SVOM core instrument is the 4–150 keV 2-D coded mask camera ECLAIRs responsible for the autonomous search and trigger of transient events within its field of view. The flight model of ECLAIRs has been built by several French labs (IRAP, CEA, APC) under the supervision of the French Space Agency (CNES). In 2021, intensive on-ground calibration has been performed on the ECLAIRs camera. Here, we give an overview of the calibration sequences of the ECLAIRs flight model and we present an overview of the main instrument performances.
The x-ray integral field unit (X-IFU) is one of the two instruments of ESA’s ATHENA space mission. It is a cryogenic x-ray spectro-imager with an unprecedented 2.5 eV resolution up to 7 keV. We present the development of the demonstrator model (DM) of X-IFU’s warm front-end electronics (WFEE). X-IFU will have around 2400 cryogenic micro-calorimeters divided into 72 time-division multiplexed (TDM) channels. The main functions of the WFEE are providing the biasing currents for the detectors and two SQUID stages and to amplify the SQUIDs output signals. Each channel requires 5 current sources (quasi-DC DACs) and a fully differential low-noise voltage amplifier (LNA). The DACs can be written and read via an I2C bus. The active component of the WFEE is the AwaXe ASIC, which was specifically designed for this project and integrates current DACs and LNAs for two TDM channels. The WFEE has also to provide housekeeping signals for power supply voltage, and on-chip ASIC temperature. Both, the final expected performances of the instrument and the general specifications of a space mission, impose strong requirements on the WFEE in terms of thermal stability, mechanical design, radiation hardness, raw performance and reliability. To validate some of these requirements, a demonstrator model of the WFEE is currently being developed to be integrated in a full readout chain for lab testing. In this paper we will discuss the PCB and mechanical assembly designs of the WFEE demonstrator model in preparation of the ATHENA space mission.

GRANDMA is a world-wide collaboration with the primary scientific goal of studying gravitational-wave sources, discovering their electromagnetic counterparts and characterizing their emission. GRANDMA involves astronomers, astrophysicists, gravitational-wave physicists, and theorists. GRANDMA is now a truly global network of telescopes, with (so far) 30 telescopes in both hemispheres. It incorporates a citizen science programme (Kilonova-Catcher) which constitutes an opportunity to spread the interest in time-domain astronomy. The telescope network is an heterogeneous set of already-existing observing facilities that operate coordinated as a single observatory. Within the network there are wide-field imagers that can observe large areas of the sky to search for optical counterparts, narrow-field instruments that do targeted searches within a predefined list of host-galaxy candidates, and larger telescopes that are devoted to characterization and follow-up of the identified counterparts. Here we present an overview of GRANDMA after the third observing run of the LIGO/VIRGO gravitational-wave observatories in 2019 − 2020 and its ongoing preparation for the forthcoming fourth observational campaign (O4). Additionally, we review the potential of GRANDMA for the discovery and follow-up of other types of astronomical transients.

The KM3NeT infrastructure consists of two deep-sea neutrino telescopes being deployed in the Mediterranean Sea. The telescopes will detect extraterrestrial and atmospheric neutrinos by means of the incident photons induced by the passage of relativistic charged particles through the seawater as a consequence of a neutrino interaction. The telescopes are configured in a three-dimensional grid of digital optical modules, each hosting 31 photomultipliers. The photomultiplier signals produced by the incident Cherenkov photons are converted into digital information consisting of the integrated pulse duration and the time at which it surpasses a chosen threshold. The digitization is done by means of time to digital converters (TDCs) embedded in the field programmable gate array of the central logic board. Subsequently, a state machine formats the acquired data for its transmission to shore. We present the architecture and performance of the front-end firmware consisting of the TDCs and the state machine.
The X-ray Integral Field Unit (X-IFU) of the ATHENA space observatory is based on a 3 kilo-pixels array of superconducting micro-calorimeters, that is read out with the Warm Front-End Electronics (WFEE) and then followed by the Digital Readout Electronics (DRE) outside the cryostat. We have developed low-noise/lowdrift amplifiers for this readout as well as performed simulations and measured the noise, bandwidth, linearity, harmonic distortion and thermal drift. Here we are presenting a realistic model of these parameters. These characterizations and models of the WFEE are necessary in order to get a full ATHENA X-IFU readout chain simulator. Impact of the WFEE low-frequency noise and its limited bandwidth on the entire X-IFU detection chain in Time Domain Multiplexing will be introduced.

The KM3NeT research infrastructure being built at the bottom of the Mediterranean Sea will host water-Cherenkov telescopes for the detection of cosmic neutrinos. The neutrino telescopes will consist of large volume three-dimensional grids of optical modules to detect the Cherenkov light from charged particles produced by neutrino-induced interactions. Each optical module houses 31 3-in. photomultiplier tubes, instrumentation for calibration of the photomultiplier signal and positioning of the optical module, and all associated electronics boards. By design, the total electrical power consumption of an optical module has been capped at seven Watts. We present an overview of the front-end and readout electronics system inside the optical module, which has been designed for a 1-ns synchronization between the clocks of all optical modules in the grid during a life time of at least 20 years.
