abstract |
Correlated charge collection phenomena in CCD sensors are presently of interest due
to their potentially major implications in space and ground based astronomy missions.
These effects may manifest as a signal dependent Point Spread Function (PSF), or as
a nonlinearity in the Photon Transfer Curve (PTC). We present the theoretical background
to a simple analytical model based on previously published solutions of Poisson's
equation which aims to aid conceptual understanding of how various device parameters
relate to the magnitude of correlated charge collection. We separate correlated charge
collection into two components - firstly excess diffusion caused by increasing drift
time as the electric field in the device decreases, which is isotropic, and secondly
anisotropic pixel boundary shifting as the fringing field in the parallel transfer
direction collapses. Equations are presented which can be solved numerically to give
reasonable detail, or solved analytically using simplifying approximations. |
