Calibration measurements for the BlackCAT CubeSat x-ray coded aperture telescope

Le résumé fourni par la source

BlackCAT is a 6U CubeSat mission scheduled for launch in December 2025. Designed for X-ray sky monitoring and observations of bright X-ray sources in the 0.5–20 keV band, the instrument will use its wide field of view and arcminute-scale localization to detect high-redshift gamma ray bursts (GRBs) and other X-ray transients. The mission will send rapid alerts of these detections, enabling prompt follow-up from other ground- and space-based observatories. The science instrument is a coded aperture telescope with a gold-plated nickel coded mask and a focal plane of four Speedster-EXD550 event-driven X-ray hybrid CMOS detectors (HCDs). We describe our methodology for the calibration of the detectors and the assembled instrument and the results of these measurements. We also briefly discuss plans for in-flight calibration and commissioning to confirm these values post-launch.
