Phase-resolved Deadtime of the Crab Pulsar Using IXPE Data

The Astrophysical Journal
After receiving an X-ray photon, an X-ray detector is not operational for a duration known as deadtime. It is detector specific and its effect on the data depends upon the luminosity of the source.

High-temperature stable and sensitive X-ray detector based on two-dimensional lead-free perovskite Cs4MnBi2Cl12 single crystal

Nano Research
Lead-halide perovskites have made great advances in direct X-ray detection due to their large mobility-lifetime (μτ), strong X-ray absorption, and ease of synthesis, but the presence of toxic lead and high ionic migration severely limit their commercial ...

A bulk Schottky junction for high-sensitivity portable radiation detectors

Nature Communications
The thickness of X-ray detectors needs to reach hundreds of micrometers to absorb X-ray, and therefore, high voltages over tens or hundreds of volts should be applied to extract X-ray-generated carriers.
