Applications of intelligent detectors
Oral presentation
Conventional x-radiography uniformly irradiates the relevant region of the patient. Across that region, however, there is likely to be significant variation in both the thickness and composition of the tissues present, which means that the x-ray exposure conditions selected, and consequently the image quality achieved, are a compromise. The I-ImaS concept eliminates this compromise by...

Applications of intelligent detectors
Oral presentation
We report on ‘proof of concept’ experiments in Pixel Imaging Mass Spectrometry (PImMS) using an ultra-fast frame-transfer CCD camera and also describe an intelligent CMOS sensor which is being developed for this application by the PImMS collaboration in the UK. PImMS is a combination of a traditional TOF mass spectrometry and of the ion imaging. Information provided by the ion imaging gives...

The GridPix detector is a gaseous Time Projection Chamber with an active pixel chip as readout plane. See ATLAS Note: ATL-UPGRADE-SLIDE-2009-141; ATL-COM UPGRADE-2009-005.- Geneva : CERN, 2009 for detailed information.
Thanks to its fine granularity, the individual electrons along a particle track, are registered...

Coupled layer and monolithic architectures
Oral presentation
A detector layout using O(cm) long, radially pointing, scintillating fibers at large radius, is investigated. Such a geometry allows discrimination between high and low pT particles based on their angle of incidence and because high pT particles deposit large ionization in one or two fibers, while low pT particles deposit small ionization in many fibers. A pixelated array of these fibers...
