Modelling Gaia CCD pixels with Silvaco 3D engineeringsoftware
Published online by Cambridge University Press: 15 February 2011
Abstract
Gaia will only achieve its unprecedented measurement accuracy requirements with detailedcalibration and correction for radiation damage. We present our Silvaco 3D engineeringsoftware model of the Gaia CCD pixel and two of its applications for Gaia: (1) physicallyinterpreting supplementary buried channel (SBC) capacity measurements (pocket-pumping andfirst pixel response) in terms of e2v manufacturing doping alignment tolerances; and (2)deriving electron densities within a charge packet as a function of the number ofconstituent electrons and 3D position within the charge packet as input to microscopicmodels being developed to simulate radiation damage.
