atterning or pixelization of anode-side of an M-π-n CdTe diode, where the pn-junction is diffused into the detector bulk, is highly motivated to improve the spatial and energy resolution by reading out the electrons instead of holes; to reduce the effects of polarization, and to be able to fabricate double sided M-π-n CdTe detector. It has been shown that very high inter-pixel resistance and...

Purpose: One of the aims of the PICASSO (Phase Imaging for Clinical Application with Silicon detector and Synchrotron radiatiOn) project of INFN-Trieste is to develop a fast data acquisition system for a single photon counting silicon micro-strip detector. The PICASSO detector is designed in order to conform to the needs of imaging large in-vivo samples like breast in the case of mammography....

This work focuses on the development of fast Charge-Coupled Devices (CCD) for X-ray detection at synchrotron radiation light sources. The presentation will first review the sensor and readout ASIC development that led to the construction of the LBNL Fast CCD (FCCD) and compact FCCD (cFCCD) camera systems, which have been successfully employed in experiments at the LBNL Advanced Light Source...

A single photon counting hybrid detector is investigated, especially with respect to linearity, maximum counting rate and dead time. These characteristics are crucial for advanced new detectors for any application and find ideal application in high-performance synchrotrons. We show that the matching of the detector response function with the temporal source structure leads to dramatic...

A Computed Tomography (CT) system with multi-slice capability based on a MicroPatterned Gaseous Detector (MPGD) is proposed for small animal imaging and envisaging mammography. This system, with energy discrimination, allows selecting energy windows for the image reconstruction and visualization. Energy weighting is also possible and lead to the enhancement of Signal to Noise Ratio (SNR) and...
