We present an updated catalog of sources detected by the Mikhail Pavlinsky ART-XC telescope aboard Spektrum-Roentgen-Gamma (SRG) observatory during its all-sky survey. It is based on data first four and partially completed fifth scans sky (ARTSS1-5). The comprises 1545 in 4–12 keV energy band. achieved sensitivity ranges between ~4 × 10 −12 erg s −1 cm −2 near ecliptic plane ~7 −13 poles, which a ~30–50% improvement over previous version two (ARTSS12). There are ~130 objects, excluding...
The Russian Space Research Institute (IKI) has developed CdTe detectors for the focal plane of ART-XC/SRG instrument. crystal dimensions about 30 × 1 mm. Top and bottom sides detector each contain 48 strips a guard ring. ASIC VA64TA1 is connected to by AC-coupling both DSSD sides. This approach allows one have same ground level electronic parts operate with different leakage currents without reconfiguration chips. One two ASICs are integrated thermal sensors Peltier cooler in big hybrid...
The Russian Space Research Institute (IKI) has developed seven flight models and three spare of the X-ray detectors for ART-XC/SRG telescope. Each detector situated in focal plane ART-XC optics includes CdTe die, front-end electronics, data processing, storage telemetry units. In performed a vibration, thermal cycling vacuum tests detectors. During this have been studied leakage current stability, polarization rate, spectroscopic imaging performance working temperature range. status...

ART-XC – a medium-x-ray-energy survey instrument of "Spectrum-Roentgen-Gamma" (SRG) project is being developed in Russia under the leadership Space Research Institute (IKI). Main requirements to telescope temperature control system are provided by two key elements module seven semiconductor DSSD CdTe detectors which have operate at −22.5±2.5 °C prevent crystals fast polarization (large time allows keep detector energy spectral characteristics during continuous 2 3 days expositions) and...
The Astronomical Roentgen Telescope – X-ray Concentrator (ART-XC) is a hard x-ray instrument with energy response 6–30 keV that will to be launched on board of the Spectrum Gamma (SRG) Mission. ART-XC consists seven co-aligned mirror modules coupled focal plane CdTe double-sided strip detectors. had been fabricated and calibrated at NASA Marshall Space Flight Center (MSFC). Russian Research Institute (IKI) has developed tested joint calibration detectors was carried out IKI test facility....
The Astronomical Roentgen Telescope X-ray Concentrator (ART-XC) is a medium instrument with operating energy range 4-30 keV which will be launched onboard the Spectrum Gamma (SRG) mission. ART-XC consists of seven co-aligned mirror modules coupled focal plane CdTe double-sided strip detectors. were fabricated and calibrated at NASA Marshall Space Flight Center (MSFC). Russian Research Institute (IKI) developed tested detector units integrated into in 2016. For more detailed studies we have...
