Compton polarimetry using double-sided segmented x-ray detectors

Gas Pixel Detectors for X-ray Polarimetry applications

We discuss a new class of Micro Pattern Gas Detectors, the Gas Pixel Detector (GPD), in which a complete integration between the gas amplification structure and the read-out electronics has been reached. An Application-Specific Integrated Circuit (ASIC) built in deep sub-micron technology has been developed to realize a monolithic device that is, at the same time, the pixelized charge collectin...

X-ray and Gamma-ray Polarimetry

X-ray imaging detectors

Astronomical x-ray polarimetry based on photoelectric effect with microgap detectors

The polarisation of x-ray photons can be determined by measuring the direction of emission of a K-shell photoelectron. Effective exploitation of this effect below 10 keV would allow development of a highly sensitive x-ray polarimeter dedicated in particular to x-ray astronomy observations. Only with the advent of finely segmented gas detectors was it possible to detect polarisation sensitivity ...

Low Noise Double - Sided Silicon Strip Detector for Multiple - Compton

A Semiconductor Multiple-Compton Telescope (SMCT) is being developed to explore the gammaray universe in an energy band 0.1–20 MeV, which is not well covered by the present or near-future gamma-ray telescopes. The key feature of the SMCT is the high energy resolution that is crucial for high angular resolution and high background rejection capability. We have developed prototype modules for a l...
