Summary
This paper describes the design, fabrication, and validation of a double-sided cadmium telluride strip detector for the FOXSI-2 solar X-ray imaging mission. The detector successfully met stringent requirements for position resolution and energy discrimination, demonstrating technical improvements over silicon detectors used in the first FOXSI flight and confirming the viability of CdTe semiconductor technology for future high-sensitivity hard X-ray solar observations.
UK applicability
This paper has no direct applicability to UK farming systems, soil health, nutrient density, or human nutrition research. It is a pure instrumentation physics study with no connection to Vitagri's Pulse Brain research domains.
Key measures
Position resolution (60 μm), detection efficiency (~100% at 4–15 keV), energy resolution (1 keV FWHM), low-energy threshold (~4 keV), sensitive area (7.67 mm × 7.67 mm)
Outcomes reported
This paper reports the development and successful deployment of a fine-pitch cadmium telluride hard X-ray detector for solar imaging aboard the FOXSI rocket experiment. The detector achieved 60 μm position resolution, ~100% efficiency in the 4–15 keV energy range, and 1 keV energy resolution, with successful image acquisition during the December 2014 FOXSI flight.
