Abstract: The detection plane of the high-energy transient camera ECLAIRs onboard Space-based multi-band Variable Objects Monitor is made of 200 XRDPIX detection modules, each consisting of a matrix of 8 × 4 Schottky-type CdTe detectors hybridized with the low-noise and low-consumption ASIC IDeF-X. The 6400 detectors are operated at −20 °C and reverse biased at –300 V, reaching a low energy threshold of 4 keV. The 20 μ s time resolution readout electronics works in photon counting mode classifying detected events as single or multiple events and measuring the deposited energy in real time. In this paper, we present the detection plane sub-systems and their main features. We also discuss its overall performances as measured both on ground and in-flight, showing compliance with the ECLAIRs science requirements.
