R&D Status of FPCCD Vertex Detector for ILD
  Fine pixel CCD (FPCCD) is one of the candidate sensor technologies for the vertex detector used for experiments at the International Linear Collider (ILC). A vertex detector system for the International Large Detector (ILD) using FPCCD sensors has been designed. We report on the R&D status of FPCCD sensors, as well as the vertex detector design for ILD.
