Implication

Experimental study demonstrates high-speed x-ray imaging spectroscopy in a hybrid sensor prototype, indicating feasible pile-up-free astronomical telescope readouts.

Key Points

High-speed x-ray imaging spectroscopy is achieved with a prototype ccd-cmos hybrid sensor, preventing photon pile-up during fast astronomical readouts.
The device demonstrated an energy resolution of 1.43keV at 22keV for single-pixel events, while charge loss occurred across multi-pixel detection areas.
Pulse height comparison among split event patterns revealed horizontal electric field non-uniformity, which adopting XRISM/Xtend CCD wafers may soon optimize.
