AbstraktAbstract

The row imaging detector 4x1 with resolution of 1024x256 pixels (0.26 Mpixels) and continuously sensitive surface is composed of four sensitive detector tiles. Each tile consists of single Timepix hybrid detector (256 x 256 pixels) with edgeless silicon sensor (150 um thick to prevent charge sharing in sensor). The whole area of the device is fully sensitive. Each pixel has integrated digital counter which counts number of particles (e.g. X-ray photons). This particle counting principle assures noiseless detection and no added noise (integration and readout noise is zero). The noiseless detection allows getting images with very high contrast and broad dynamic range (theoretically unlimited). Therefore even low mass objects (e.g. soft materials) are imaged with high contrast.
