CCD-based sensor development for the vertex detector at the ILC

The linear collider flavour identification (LCFI) collaboration is engaged in R&D towards a CCD-based vertex detector for the international linear collider (ILC). The demanding requirements for small pixel size, low mass and low occupancy readout pose significant challenges to the sensor development. We are working on two detector technologies, the column parallel CCD (CPCCD) and the In-situ Storage Image Sensor (ISIS). The evaluation of our second generation CPCCD (CPC2) and its readout and driver chips is presently in an advanced stage. In stand-alone mode CPC2 achieved operation at 45 MHz, which is a major milestone. After the successful proof- of-principle first generation ISIS1 we are now planning to continue with new, more advanced device. In this work we present the status and the tests results from our CPCCD and ISIS developments.
