Özet

The iXRD is the primary science payload on Sharjah-Sat-1, a 3U CubeSat expected to be launched in Q4, 2022. Its main scientific goal is monitoring bright hard X-ray sources and transients in 20 - 200 keV band. The iXRD consists of a CdZnTe crystal (6.45 cm² area, 5 mm thickness), a Tungsten collimator with square holes with an opening angle of 4.26^∘, readout and control electronics and power supply circuitry, a back-shield and mechanical structures. Some of the design elements of iXRD have been inherited from the XRD on BeEagleSat with significant improvements in terms of collecting area, X-ray background and electronic noise. In this article, the design of the iXRD is discussed in detail taking into account mechanical, electronic, control software and data handling aspects. Its expected performance is determined after ground calibration. Depending on the pixel size, the energy resolution is 4 - 7 keV at 60 keV and the minimum detectable energy is 19 - 23 keV.

BlackCAT is a 6U mission, and one of its scientific objectives, detecting and studying black holes in outburst, is similar to the main objective of Sharjah-Sat-1. BlackCAT has a wide field of view [] through a coded mask, and uses Hybrid CMOS X-ray detectors operating in the 1-20 keV band. BlackCat is being funded by a NASA APRA grant and is expected to be launched in 2024. The development of iXRD has been supported by University of Sharjah, Sabancı University and Tübitak Project 116F151. The authors thank Süleyman Çelik at SUNUM, Sabanci University for critical technical support in crystal attachment.
