Charge Transfer Inefficiency Studies for CCD Vertex Detectors at a LC
The Linear Collider Flavour Identification (LCFI) collaboration studies CCD detectors for quark flavour identification in the framework of a future linear e+e- collider. The flavour identification is based on precision reconstruction of charged tracks very close to the interaction point. Therefore, this detector will be exposed to a high level of radiation and thus an important aspect of the vertex detector development are radiation hardness studies. Results of detailed simulations of the charged transport properties of a CCD prototype chip are reported and compared with initial measurements. The simulation program allows to study the effect of radiation damage after the exposure of the detector to a realistic radiation dose, which is expected in the environment of detector operation at a future LC.
