AbstraktAbstract

The large area imaging detector WidePix 4x5 with resolution of 1280x1024 pixels (1.3 Mpixels) and continuously sensitive area is composed of a matrix of sensitive detector tiles. Each tile consists of single Timepix hybrid detector (256 x 256 pixels) with edgeless silicon sensor. Thus the whole area of the WidePix 4x5 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. plastic or soft tissue) are imaged with high contrast. The detector is modified for imaging with thermal neutrons.
