The coded mask of the ECLAIRs telescope onboard the SVOM space mission

Cyril Lachaud, Alain Givaudan, Maurice Karakac, Walter Bertoli et autres

Abstract ECLAIRs is a hard X-ray coded-mask telescope onboard the SVOM space mission, designed to detect and localize high-energy transients, in particular gamma-ray bursts. Operating over the 4–150 keV energy range, ECLAIRs extends coded-mask imaging to an unusually low-energy threshold. Achieving sensitivity …
