AbstraktAbstract

The Timepix device is a pixelated silicon detector. Because of its structure, an incoming particle can deposit its energy in several adjacent pixels as a result of the charge sharing effect. The distribution of energy in the pixels activated by a heavy charged particle can be exploited to determine the entering point of the particle with a precision better than the pixel dimensions. This is experimentally illustrated by images of different samples obtained with alpha particles. This work was carried out within the CERN Medipix Collaboration.
