PPT-Semiconductor Detectors Track

Overview David Christian Fermilab June 9 2011 Outline History Why semiconductor detectors Concentrating on silicon Energy Resolution Position Resolution leverage of IC technology Transition to the present. Introduction Germanium detectors are semiconductor diodes having a p-i-n structure in which the intrinsic (i) region is sensitive to ionizing radiation, particularly x rays and gamma rays.
