Abstract
In the framework of an experimental study of the possibility of using a double-sided silicon strip detector for digital radiography, and electronic system has been developed to make the signals coming from the two sides of the crystal coincide and hence to define the impact point of X-rays, giving an image matrix as final output. It is based on commercial PALs, and has been built and tested for 32×32 channels. In this configuration the dead time between two subsequent events is ⩽34 ns. Its logic is easily extendable to a large number of channels with a limited increase of the overall dead time and its various stages have been devised in view of a future integration as VLSII documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
